Potential Effects of Essential Oil from Plinia cauliflora (Mart.) Kausel on Leishmania: In Vivo, In Vitro, and In Silico Approaches. Microorganisms 2024; 12:207. [PMID: 38276192 PMCID: PMC10819817 DOI: 10.3390/microorganisms12010207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Revised: 11/23/2023] [Accepted: 11/28/2023] [Indexed: 01/27/2024] Open
Abstract
In the search for new chemotherapeutic alternatives for cutaneous leishmaniasis (CL), essential oils are promising due to their diverse biological potential. In this study, we aimed to investigate the chemical composition and leishmanicidal and anti-inflammatory potential of the essential oil isolated from the leaves of Plinia cauliflora (PCEO). The chemical composition of PCEO showed β-cis-Caryophyllene (24.4%), epi-γ-Eudesmol (8%), 2-Naphthalenemethanol[decahydro-alpha] (8%), and trans-Calamenene (6.6%) as its major constituents. Our results showed that the PCEO has moderate cytotoxicity (CC50) of 137.4 and 143.7 μg/mL on mice peritoneal exudate cells (mPEC) and Vero cells, respectively. The PCEO was able to significantly decrease mPEC infection by Leishmania amazonensis and Leishmania braziliensis. The value of the inhibitory concentration (IC50) on amastigote forms was about 7.3 µg/mL (L. amazonensis) and 7.2 µg/mL (L. braziliensis). We showed that PCEO induced drastic ultrastructural changes in both species of Leishmania and had a high selectivity index (SI) > 18. The in silico ADMET analysis pointed out that PCEO can be used for the development of oral and/or topical formulation in the treatment of CL. In addition, we also demonstrated the in vivo anti-inflammatory effect, with a 95% reduction in paw edema and a decrease by at least 21.4% in migration immune cells in animals treated with 50 mg/kg of PCEO. Taken together, our results demonstrate that PCEO is a promising topical therapeutic agent against CL.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 302:115916. [PMID: 36379417 DOI: 10.1016/j.jep.2022.115916] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/06/2022] [Revised: 10/20/2022] [Accepted: 11/04/2022] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Mesosphaerum pectinatum (L.) Kuntze (Lamiaceae), also known as sambacaitá, is a medicinal plant widely used in northeastern Brazil for the treatment of inflammatory and painful conditions, bacterial infections and cancer. Hence, the medicinal use of this species is quite meaningful to the search for bioactive compounds. AIM OF THE STUDY To evaluate the antinociceptive and anti-inflammatory activities of the pectinolide-enriched fraction of Mesosphaerum pectinatum (PEF) in animal models. MATERIALS AND METHODS The PEF was analyzed with HPLC-DAD and 1H and 13C NMR. After the analysis, compounds of the pectinolide class were detected as major constituents in this fraction. The PEF (50, 100 and 200 mg/kg, p.o.) and the reference drugs - morphine (3.0 mg/kg, p.o.) and dexamethasone (2.0 mg/kg, p.o.) - were evaluated using models for nociception (hot plate, formalin-induced licking response) or inflammation (carrageenan-induced peritonitis and ear edema model). RESULTS The PEF significantly decreased the licking time of the animals treated when compared to the control group (second phase). In the carrageenan-induced peritonitis model, PEF (100 and 200 mg/kg) significantly decreased total and differential leukocyte counts. The PEF (0.3, 1.0 and 3.0 mg/ear) significantly reduced mice ear edema at the same extent and like the results obtained with the standard drug (dexamethasone). The MPO activity was reduced in mice ear at doses of 1 and 3 mg/ear. Antinociceptive effect on the hot plate test was not observed, demonstrating that there is no analgesic activity. CONCLUSION Our results suggest that the pectinolide-enriched fraction exhibits anti-inflammatory effects and that it is involved with inhibiting the release of the inflammatory mediators.

Adv Pharm Bull 2023; 13:150-159. [PMID: 36721819 PMCID: PMC9871284 DOI: 10.34172/apb.2023.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2021] [Revised: 09/01/2021] [Accepted: 09/28/2021] [Indexed: 02/03/2023] Open
Abstract
Purpose: The emergence of the COVID-19 pandemic has led to the search for potential therapeutic responses for various aspects of this disease. Fruits of Pterodon emarginatus Vogel (Fabaceae), sucupira, have been used in Brazilian traditional medicine because of their anti-inflammatory properties, which have been proven in vivo, in vitro, and in silico. Therefore, the aim of this work is to evaluate P. emarginatus oleoresin and isolated diterpenes by in vitro anti-inflammatory models. Methods: In this study, the mechanisms underlying the anti-inflammatory activity of P. emarginatus oleoresin and vouacapanes 6α,19β-diacetoxy-7β,14β-dihydroxyvouacapan (V1), 6α-acetoxy-7β,14β-dihydroxyvouacapan (V2), and methyl 6α-acetoxy-7β-hydroxyvouacapan-17β-oate (V3) were investigated in HaCaT cells. Results: Oleoresin, V2, and V3 inhibited phospholipase A2 (30.78%, 24.96%, and 77.64%, respectively). Both vouacapanes also inhibited the expression of COX-2 (28.3% and 33.17%, respectively). The production of interleukin 6 (IL-6) was inhibited by oleoresin by 35.47%. However, oleoresin did not interfere with Nrf-2 expression or IL-8 production. Conclusion: The results support the ethnomedicinal use of P. emarginatus oleoresin as an anti-inflammatory herbal medicine, and also highlight P. emarginatus oleoresin and isolated vouacapanes as an attractive therapeutic approach for COVID-19 through the reduction or chronological control of the inflammatory mediators IL-6, cyclooxygenase-2 (COX-2), phospholipase A2, and INF-y (indirectly) during the SARS-CoV-2 infection process.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Indigofera suffruticosa has reports of its popular use for analgesy in several cultures. Besides that, all parts of this plant are used for some medicinal outcome. The leaves are used in teas, decoctions, juices and included in baths for treating fever and inflammatory processes. AIM OF THE STUDY To evaluate the anti-inflammatory activity mechanisms of I. suffruticosa leave aqueous extract (IsAE). MATERIALS AND METHODS Phytochemical screening of IsAE was performed by thin layer chromatography. Total flavonoid content was determined and expressed by milligram of quercetin equivalent per gram of extract (mgEQ/g). 50% of the lethal dose that kills animals (LD50) was determined by acute toxicity in mice. Anti-inflammatory activity was evaluated through carrageenan-induced paw edema, peritonitis, and protein denaturation inhibition. Anti-nociceptive potential was evaluated by acetic acid-induced writhing and formalin tests. Antipyretic activity was assessed by yeast-induced fever. RESULTS Phytochemical analysis revealed the presence of flavonoids and acid gallic in a quantity of 33.9 mg QE/g. Acute toxicity evaluation resulted in a LD50 of 3807.88 mg/kg. For carrageenan-induced paw edema test, IsAE in both doses (20 and 100 mg/kg) reduced the edema in 83.93%. IsAE reduced nitric oxide (NO) production and leucocytes migration to peritonitis inflammation site and at a concentration of 0.5 mg/mL showed also inhibition of protein denaturation similar to indomethacin in the same concentration. IsAE inhibited in 72.60% the number of contortions in writhing test. In formalin test, IsAE was also efficient, but showed results only in the second phase. In addition, the concentration of 100 mg/kg reduced fever significantly. CONCLUSIONS IsAE proved to be anti-inflammatory, acting in different parts of the inflammation process, confirming its popular use.

Abstract
BACKGROUND From the fruits and seeds of the species of Pterodon, it is possible to obtain two main products: the essential oil and oleoresin. In oleoresin, numerous vouacapan compounds have been demonstrated to have biological potential, including insecticidal activity. OBJECTIVE In silico studies were performed to identify potential candidates for natural insecticides among the vouacapans present in the genus Pterodon. MATERIALS AND METHODS Molecular docking and molecular dynamics studies were performed to analyze the interaction of vouacapan compounds with acetylcholinesterase of Drosophila melanogaster. Pharmacokinetic parameters regarding physicochemical properties, plasma protein binding, and activity in the central nervous system were evaluated. The toxicological properties of the selected molecules were predicted using Malathion as the reference compound. RESULTS 6α,7β-dimethoxivouacapan-17-ene (15) showed a high number of interactions and scores in molecular docking studies. This result suggests that this compound exhibits an inhibitory activity of the enzyme acetylcholinesterase. Regarding physicochemical properties, this compound showed the best results, besides presenting low cutaneous permeability values, suggesting null absorption. Molecular dynamics studies demonstrated few conformational changes in the structure of the complex formed by compound 4 and acetylcholinesterase enzyme throughout the simulation time. CONCLUSION It was determined that compound 4 (vouacapan 6α,7β,17β,19-tetraol) is an excellent candidate for usage as a natural insecticide.

Abstract
In the last few decades, utilization of medicinal plants by the pharmaceutical industry has led to the identification of many new bioactive compounds. The genus Pterodon, native of the Brazilian Flora, is known for the therapeutic properties attributed to its species, which are widely used in popular medicine for their anti-inflammatory, anti-rheumatic, tonic, and depurative properties. The intrinsic low water solubility of the plant derivatives from the genus, including diterpenes with vouacapane skeletons that are partially associated with the pharmacological activities, impairs the bioavailability of these bioactive compounds. Recent studies have aimed to encapsulate Pterodon products to improve their water solubility, achieve stability, increase their efficacy, and allow clinical applications. The purpose of this paper is to review recent research on the use of nanotechnology for the development of new products from plant derivatives of the Pterodon genus in different types of micro- and nanocarriers. Therapeutic properties of their different products are also presented. Finally, an update about the current and future applications of encapsulated formulations is provided.

Efficacy of nanoemulsion with Pterodon emarginatus Vogel oleoresin for topical treatment of cutaneous leishmaniasis. Biomed Pharmacother 2021; 134:111109. [PMID: 33341050 DOI: 10.1016/j.biopha.2020.111109] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 11/29/2020] [Accepted: 12/04/2020] [Indexed: 12/15/2022] Open
Abstract
Cutaneous leishmaniasis (CL) is a neglected tropical skin disease caused by the protozoan genus Leishmania. The treatment is restricted to a handful number of drugs that exhibit toxic effects, limited efficacy, and drug resistance. Additionally, developing an effective topical treatment is still an enormous unmet medical challenge. Natural oils, e.g. the oleoresin from P. emarginatus fruits (SO), contain various bioactive molecules, especially terpenoid compounds such as diterpenes and sesquiterpenes. However, its use in topical formulations can be impaired due to the natural barrier of the skin for low water solubility compounds. Nanoemulsions (NE) are drug delivery systems able to increase penetration of lipophilic compounds throughout the skin, improving their topical effect. In this context, we propose the use of SO-containing NE (SO-NE) for CL treatment. The SO-NE was produced by a low energy method and presented suitable physicochemical characteristic: average diameter and polydispersity index lower than 180 nm and 0.2, respectively. Leishmania (Leishmania) amazonensis-infected BALB/c mice were given topical doses of SO or SO-NE. The topical use of a combination of SO-NE and intraperitoneal meglumine antimoniate reduced lesion size by 41 % and tissue regeneration was proven by histopathological analyses. In addition, a reduction in the parasitic load and decreased in the level of IFN-γ in the lesion may be associated, as well as a lower level of the cytokine IL-10 may be associated with a less intense inflammatory process. The present study suggests that SO-NE in combination meglumine antimoniate represents a promising alternative for the topical treatment of CL caused by L. (L.) amazonensis.

Pterodon pubescens Benth. is widely used in folk medicine for the treatment of inflammatory conditions, with the activity attributed to the compounds with a vouacapan moiety, however, few studies report the toxicological evaluation of the extract and safety issues related to the species. Herein the non-clinical toxicity, in in vivo and in vitro tests, of dichloromethane crude extract of Pterodon pubescens fruits (PPE) and vouacapan diterpene furan isomer´s mixture (1:1) 6α-hydroxy-7β-acetoxy-vouacapan-17β-oate methyl ester and 6α-acetoxy-7β-hydroxy-vouacapan-17β-oate methyl ester isomers (VDFI mixture) is reported. Toxicological evaluation of 110-day repeated dose oral toxicity study, as hematological, biochemical, and histopathological parameters demonstrated that animals (male and female Wistar rats) treated with PPE presented no signs of toxicity, nevertheless daily high dose administration (500 mg/Kg) altered the metabolic homeostasis of animals that manifested microgoticular hepatic steatosis. Biochemical and histopathological results of animals (female Swiss mice) treated daily with VDFI mixture, at the highest dose (300 mg/Kg), indicated liver toxicity in one animal causing acute hepatotoxicity. Alkaline Comet assay demonstrated that PPE and VDFI mixture increased the percentage of DNA fragmentation without interfering with the tail moment parameter, but only VDFI mixture (30 µg/mL) presented statistical difference. In the micronucleus induction test, PPE and VDFI mixture did not demonstrate mutagenic potential. Our data provide evidence for the safety use of PPE and VDFI mixture in lower doses enabling further clinical studies and the development of herbal medicine.

Abstract
Varronia multispicata (Cham.) Borhidi (Cordiaceae), an herbaceous plant distributed in tropical and subtropical regions is native of Brazil and widely used in folk medicine to treat respiratory and digestive diseases, inflammation, and some types of infections. Thus, this study aimed to investigate acute oral toxicity, antinociceptive, and anti-inflammatory activities of dry aqueous extract of V. multispicata (AEVm) and to identify its compounds. Extract was obtained by lyophilized leaf infusion and its composition was analyzed by ultra-performance liquid chromatography-high resolution mass spectrometry (LC-MS). Acute oral toxicity was evaluated in female rats treated with AEVm (2,000 mg/kg) in a single oral dose. Mortality, body weight changes, feed and water intake, organ weights, histological and biochemical parameters were screened for 14 days. Antinociceptive activity was evaluated by writhing (WT), formalin (FT), and hot plate (HP) tests in male mice while anti-inflammatory activity was performed by carrageenan (CPE) and dextran (DPE)-induced paw edema tests and carrageenan-induced peritonitis (CP) test in male rats. Additionally, spontaneous open-field (OF) locomotion was evaluated. LC-MS analysis revealed the presence of flavonoids with biological activity. In toxicity evaluation, extract did not cause deaths in dose of 2,000 mg/kg, and there were no significant behavioral or biochemical alterations. Additionally, evidence of hepatoprotective and antioxidant activity was observed. In pharmacological evaluation AEVm showed dose-dependent antinociceptive activity in WT, with a median effective dose of 146.89 mg/kg, which showed selectivity by inflammatory base processes (FT first phase; p < 0.001), showing no activity in neuropathic nociception components (FT second phase and HP) or about consciousness and locomotion in OF. AEVm also showed significant anti-inflammatory activity, inhibiting CPE (p < 0.001) and cell migration (p < 0.05) and nitric oxide (NO) production (p < 0,01) in CP test. These data demonstrate that AEVm has low oral toxicity—with evidence of hepatoprotective and antioxidant properties—antinociceptive and anti-inflammatory activity, supporting V. multispicata traditional use, possibly related to flavonoids present in its constitution.

Abstract
OBJECTIVES Bioactive molecules derived from natural products combine the ability to absorb UV light and act as antioxidants. We developed an oil-based sucupira (native species of the Brazilian cerrado) nanoemulsion (NE) using a high-energy emulsification method and assessed its effectiveness in vitro. METHODS An easily scalable high-pressure homogenization method was used to prepare the formulation. NE droplets mean diameter, pH, stability, conductivity and morphology were analysed. Formulation bioactivity was assessed using HaCaT cells. KEY FINDINGS The formulation presented suitable pH and size for topic administration and was stable for over 90 days upon storage at 4, 25 and 45°C. The NE showed protective effect against oxidative stress and reduced levels of UVA-induced pro-inflammatory cytokines IL-6 and IL-8. CONCLUSIONS A novel, stable and easily prepared formulation was obtained for encapsulation of sucupira oil. The protective effect of the formulation by cytokine inhibition in the early stage of the inflammatory process was shown in vitro. Combined with the antioxidant effect by inhibition of reactive oxygen species, the use of sucupira oil NE for prevention and treatment of UVA-induced stress could contribute to decrease the effects of UV radiation on skin ageing.

Abstract
CONTEXT Inflammatory disorders are common in modern life, and medicinal plants provide an interesting source for new compounds bearing anti-inflammatory properties. In this regard, Brazilian medicinal plants are considered to be a promising supply of such compounds due to their great biodiversity. OBJECTIVES To undertake a review on Brazilian medicinal plants with corroborated anti-inflammatory activities by selecting data from the literature reporting the efficacy of plants used in folk medicine as anti-inflammatory, including the mechanisms of action of their extracts and isolated compounds. METHODS A search in the literature was undertaken by using the following Web tools: Web of Science, SciFinder, Pub-Med and Science Direct. The terms 'anti-inflammatory' and 'Brazilian medicinal plants' were used as keywords in search engine. Tropicos and Reflora websites were used to verify the origin of the plants, and only the native plants of Brazil were included in this review. The publications reporting the use of well-accepted scientific protocols to corroborate the anti-inflammatory activities of Brazilian medicinal plants with anti-inflammatory potential were considered. RESULTS We selected 70 Brazilian medicinal plants with anti-inflammatory activity. The plants were grouped according to their anti-inflammatory mechanisms of action. The main mechanisms involved inflammatory mediators, such as interleukins (ILs), nuclear factor kappa B (NF-κB), prostaglandin E2 (PGE2), cyclooxygenase (COX) and reactive oxygen species (ROS). CONCLUSIONS The collected data on Brazilian medicinal plants, in the form of crude extract and/or isolated compounds, showed significant anti-inflammatory activities involving different mechanisms of action, indicating Brazilian plants as an important source of anti-inflammatory compounds.

Abstract
ETHNOBOTANICAL RELEVANCE The oil obtained from the fruits of Pterodon emarginatus Vog. (OPe) is used orally and topically, in traditional medicine for some purposes, such as acute and chronic inflammatory states as rheumatoid arthritis. MATERIALS AND METHODS In this work, the anti-inflammatory activity of the OPe was demonstrated based on several animal models and presented an in silico study based on the 6α,7β-dihydroxy-vouacapan-17β-oic acid (DHVA) majority compound of the OPe to evaluate the interaction this compound, with cyclooxygenase-2 (COX-2) in 4COX (Mus musculus) and 5KIR (Homo sapiens) and molecular dynamics simulation. RESULTS The OPe (498 mg/kg, p.o) significantly inhibited (p < 0.05, Student t-test) the primary and secondary reactions of arthritis by Freund's Complete Adjuvant (FCA) and in dermatitis induced by croton oil in mice, OPe inhibited peak of edema. In vascular permeability test in rats, the treatment with OPe was able to block the response to PGE2, serotonin, and bradykinin (p < 0.05, Student t-test). In the writhing test in mice, the OPe at doses of 498 and 980 mg/kg (p.o) produced inhibition of 73% and 92%, respectively, and was not significantly effective in the hot plate test. In the evaluation of the potency in relation to gastric injury (gastric ulcer induced by stress) and combined assay in the assessment of anti-inflammatory potency and gastric damage, it was observed that indomethacin (10 mg/kg, p.o.) inhibited carrageenan edema by 51% and produced a higher number of gastric lesions when compared to the group treated with OPe, where only areas of hyperemia were observed, without the occurrence of ulcerative lesion, and which inhibited the edema by 47%. In the in silico study, it was found that the DHVA is capable of binding to two organisms (4COX - Mus musculus and 5KIR - Homo sapiens), however, with higher binding affinity to the organism Homo sapiens. CONCLUSIONS As expected, all tested ligands were capable of forming hydrogen interactions with residues at their respective binding sites, but the DHVA ligand was capable of creating slightly more hydrogen bonds when docked to either 4COX or 5KIR than the other tested ligands, thus demonstrating the participation of this compound in the anti-inflammatory and antialgic responses observed in the in vivo assays as a COX-2 inhibitor. Therefore, the results obtained support the traditional use of OPe for inflammatory and gastric problems.

Abstract
Microwave-assisted extraction of volatile oils (MAE) potentially offers a more efficient and bio-sustainable method than conventional extraction by Clevenger apparatus (CE). This study aimed to optimise the MAE of the volatile oil from Pterodon emarginatus fruits and characterise the volatile compounds. A 23 full-factorial central composite design and response surface methodology were used to evaluate the effects of time (min), moisture (%) and microwave power (W) on the extraction yield. The process optimisation was based on the desirability function approach. The reaction time and moisture conditions were standardised in these analyses. The volatile oil composition was analysed by Gas Chromatography/Mass Spectrometry (GC/MS) in order to compare techniques extractions influences. Microwave irradiation showed excellent performance for extraction of the volatile oil from Pterodon emarginatus and there were some advantages in compare to conventional method with respect to the time (14 times), energy (6 times), reagents amounts and waste formation. About chemical composition presents significant differences with the type of extraction. Caryophyllene (25.65%) and trans-α-bisabolol (6.24%) were identified as major components in MAE sample while caryophyllene (6.75%) and γ-elemene (7.02%) are the components with higher relative percentage in CE samples. The microwaves assisted process shown an increase of economic interested compounds present in volatile oil.

Abstract
ETHNOPHARMACOLOGICAL IMPORTANCE Currently, in many traditional communities, such as the riverine community in the North Araguaia microregion (Mato Grosso, Brazil), plant knowledge and use represent the main, if not the only, therapeutic resource for the maintenance of health and/or treatment of diseases. This study aimed to identify and document species of medicinal plants used by local experts from riverine communities in the North Araguaia microregion in Mato Grosso State, and to further chemical and pharmacological studies on species selected based on searches in the relevant literature. MATERIALS AND METHODS This is a cross-sectional ethnobotanical study, with non-probabilistic sampling (n =60), that applied the snowball method to select local riverine experts who understand medicinal plant use. Socio-demographic, ethnobotanical and ethnopharmacological data (vernacular name, uses, geographical origin, habit, method of preparation and part used) on medicinal plants were collected during semi-structured interviews. The results were analyzed by descriptive and quantitative means: indices of use-report (UR) were used to select plant species with therapeutic potential. RESULTS In total, 309 plant species belonging to 86 botanical families were cited; 73% were native to Brazil, and Fabaceae was the most representative family (11.3%). Arboreal was the predominant life form (37.2%). The leaf was the most used part (28.9%). Infusion was the most commonly reported method of preparation (31.3%). The plants reported in the survey were indicated for 18 of the 22 ICD-10 disease categories. The disease categories most commonly cited were the infectious and parasitic diseases (IPD, 718 UR), digestive system diseases (DSD, 565 UR) and respiratory system diseases (RSD, 504 UR), representing 16.6%, 13.1% and 11.7%, respectively of the total UR. Dysphania ambrosioides L. was the most sighted in the IPD category 50 UR. Copaifera langsdorffii Desf. (133), Lafoensia pacari A. St.-Hil. (131), and Cecropia pachystachya Trécul (126) were the species with the highest UR. Bidens pilosa L., Vernonia ferruginea Less, and L. pacari, respectively, were the most cited native plants used to treat such diseases. Of the 8 investigated native plants, C. langsdorffii, and Brosimum gaudichaudii are the most prominent: in addition to having been widely studied, in terms of phytochemical and pharmacological, these species have been marketed as pharmaceutical products, with associated patent deposits. CONCLUSIONS Local riverine experts from the North Araguaia microregion use a wide variety of medicinal plants in self-care health, especially those species used to treat IPD. The therapeutic potential of some of these plants has been scientifically validated; however, there are other species whose pharmacological effects and safety remain to be properly investigated. Thus, the present study, aside from being a basis for future chemical, pharmacological and agronomic bioprospecting studies, may contribute to the development of the management, conservation and sustainable use of medicinal flora in the microregion studied.

Abstract
Pterodon genus fruits are commercially available at the Brazilian medicinal market used in folk medicine due to their anti-inflammatory, analgesic, and anti-rheumatic effects. Previous studies demonstrated that furanditerpenes possessing vouacapan skeleton, isolated from Pterodon genus, possess expressive antinociceptive activities, with promising moiety for the development of new analgesic products. The antinociceptive properties of compounds 6α,7β-6α-hidroxivouacapan-7β-17β-lactone (HVL) and 6α-oxovouacapan-7β-17β-lactone (OVL), semi-synthetic analogues of furanditerpenes previously reported as analgesic agents were evaluated on animal experimental models (Spindola et al., 2010, 2011). The chemical-induced pain methods used in the present work, demonstrated for the first time that both compounds HVL and OVL have potential as important templates for the development of chronic pain control drugs. The main findings of this work were that both compounds were: effective in the writhing test; reduced paw edema in the carrageenan test; effective in the inflammatory phase of the formalin test corroborating their activity against inflammatory pain conditions; effective on reducing pain through the stimulation of vanilloid receptors sensible to capsaicin (an important pathway for chronic pain maintenance); reduced the pain stimulus caused by PGE2 injection (a pathway involved in chronic pain hypersensitivity); effective on decreasing mechanical allodynia in the CFA-model, demonstrating their potential use against chronic pain disorders.

Development of a Larvicidal Nanoemulsion with Pterodon emarginatus Vogel Oil. PLoS One 2016; 11:e0145835. [PMID: 26742099 PMCID: PMC4711774 DOI: 10.1371/journal.pone.0145835] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2015] [Accepted: 12/09/2015] [Indexed: 12/20/2022] Open
Abstract
Pterodon emarginatus Vogel is a Brazilian species that belongs to the family Fabaceae, popularly known as sucupira. Its oil has several biological activities, including potent larvicidal property against Aedes aegypti. This insect is the vector of dengue, a tropical disease that has been considered a critical health problem in developing countries, such as Brazil. Most of dengue control methods involve larvicidal agents suspended or diluted in water and making active lipophilic natural products available is therefore considered a technological challenge. In this context, nanoemulsions appear as viable alternatives to solve this major problem. The present study describes the development of a novel nanoemulsion with larvicidal activity against A. aegypti along with the required Hydrophile Lipophile Balance determination of this oil. It was suggested that the mechanism of action might involve reversible inhibition of acetylcholinesterase and our results also suggest that the P. emarginatus nanoemulsion is not toxic for mammals. Thus, it contributes significantly to alternative integrative practices of dengue control, as well as to develop sucupira based nanoproducts for application in aqueous media.

Abstract
Trees of the genus Pterodon, commonly known as “sucupira-branca” or “faveira,” are native to central Brazil. The Pterodon fruits are traditionally used in ethnomedicine as an infusion, in small doses, and at regular time intervals as an antirheumatic, anti-inflammatory, tonic, and depurative agent. The various compounds present in the Pterodon class are, generally, water-insoluble and derived from the fusion of high-molecular weight pentacarbonate units. Scientific research has shown that the major compounds isolated from Pterodon species are linear and/or tetracyclic diterpenes with vouacapane skeletons that partly underlie the pharmacological activities of the fruit-derived oil. Material from Pterodon species has several biological properties, such as analgesic, anti-inflammatory, and anticancer effects. Therefore, recent studies have sought to microencapsulate these extracts to protect them from potential chemical degradation and improve their water solubility, ensuring greater stability and quality of the end products. This review presents a succinct overview of the available scientific evidence of the biological activity and toxicity of Pterodon species in addition to other important aspects, including phytochemical and technological features.

Abstract
Synthesis of compounds analogous to natural products from secondary metabolites, such as flavonoids, is a promising source of novel drugs. Rutin (quercetin-3-O-rutinoside) is a natural flavone, which has, in its chemical structure, different sites for coordination with transition metals and the complexation with these metals enhances its biological properties. Rutin-zinc(II), a flavonoid-metal complex, was synthesized and characterized by UV-VIS, FT-IR, elemental analysis and (1)H NMR. The antioxidant and antitumor activities, as well as the cytotoxicity and in vivo toxicity of this complex were evaluated and compared with the free rutin. Rutin-zinc(II) has not shown any cytotoxicity against normal cells (fibroblasts and HUVECs) or toxicity in BALB/c mice, but has shown antioxidant activity in vitro and cytotoxicity against leukemia (KG1, K562 and Jurkat), multiple myeloma (RPMI8226) and melanoma (B16F10 and SK-Mel-28) cell lines in vitro. In Ehrlich ascites carcinoma model, Rutin-zinc(II) modulated the mitochondrial membrane potential and the expression of genes related to cell cycle progression, angiogenesis and apoptosis.

Abstract
This article reports the development of a pharmaceutical product containing vegetable actives from a Brazilian medicinal plant. The possibility of forming a microemulsion using Pterodon emarginatus ("sucupira") oil was evaluated and the anti-inflammatory potential of this microemulsion was also examined. A formulation was developed using P. emarginatus oil, a mixture of ethoxylated Castor Oil (Ultramone(r) R-540/propylene glycol 2:1) (surfactant/cosurfactant) and distilled water at a ratio of 10:15:75, respectively. The microemulsion which was selected was then subjected to the preliminary stability test and analyzed in terms of average diameter of droplets, pH, zeta potential, and polydispersity index, on the 1st, 7th, 15th, and 30th days after preparation and stored at different temperatures (5 ± 2 °C, 25 ± 2 °C, and 40 ± 2 °C). The anti-inflammatory in vivo activity of both oil and formulation were evaluated, using the experimental model of croton oil-induced ear edema. The preliminary stability test showed that the microemulsion stored at 5 and 25 °C retained its original features throughout the 30-day period. The anti-inflammatory potential of both oil and formulation was shown to be statistically significant (p < 0.001), when compared to the control group, however, the microemulsion proved to be more effective (p < 0.05) than the oil when applied directly to the ear.

Abstract
An oleaginous fraction obtained from an alcohol extract of the fruit of Pterodon pubescensBenth. (FHPp) was microencapsulated in polymeric systems. These systems were developed using a complex coacervation method and consisted of alginate/medium-molecular-weight chitosan (F1-MC), alginate/chitosan with greater than 75% deacetylation (F2-MC), and alginate/low-molecular-weight chitosan (F3-MC). These developed systems have the potential to both mask the taste of the extract, and to protect its constituents against possible chemical degradation. The influence of the formulation parameters and process were determined by chemical profiling and measurement of the microencapsulation efficiency of the oleaginous fraction, and by assessment of microcapsule morphology. The obtained formulations were slightly yellow, odorless, and had a pleasant taste. The average diameters of the microcapsules were 0.4679 µm (F2-MC), 0.5885 µm (F3-MC), and 0.9033 µm (F1-MC). The best formulation was F3-MC, with FHPp microencapsulation efficiency of 61.01 ± 2.00% and an in vitro release profile of 75.88 ± 0.45%; the content of vouacapans 3-4 was 99.49 ± 2.80%. The best model to describe the release kinetics for F1-MC and F3-MC was that proposed by Higuchi; however, F2-MC release displayed first-order kinetics; the release mechanism was of the supercase II type for all formulations.

Abstract
Several studies have demonstrated the analgesic and anti-inflammatory effects of fruit and seed extracts from Pterodon emarginatus Vogel (Fabaceae). The objective of this study was to evaluate the antinociceptive activity of the hydroethanolic extract of P. emarginatus leaves in mice and characterize its chemical composition using HPLC coupled to UV-vis diode array detection and mass spectrometry with electrospray ionization. Our results showed that the doses of 500 and 1000 mg/kg produced an antinociceptive effect, as observed in the hot plate test and writhing induced by acetic acid. The chromatographic profile and spectral mass data suggest the presence of di-C-glycosylflavones (e.g., vicenin-2 and schaftoside), C,O-glycosylflavones (e.g., chrysoeriol-8-C-glucosyl-2″-O-glucuronide-6-C-arabinoside) and luteolin-7-O-rutinoside as the main constituents. Lower levels of oleanane-type saponins, such as soyasaponin Bb and Be, and the saponin derivatives hederagenin and aglycone B, which are typical of Fabaceae family, were also found. From this study, it is suggested that the analgesic effect observed is not due to the terpenoids previously reported from fruit and seed extracts, but could be attributed to flavones and the hederagenin derivatives that were identified as main constituents of the hydroethanolic extract from the leaves.

Abstract
The aim of the present study was to evaluate the anti-inflammatory activities of aqueous extract of Bixa orellana (AEBO) leaves and its possible mechanisms in animal models. The anti-inflammatory activity of the extract was evaluated using serotonin-induced rat paw edema, increased peritoneal vascular permeability, and leukocyte infiltrations in an air-pouch model. Nitric oxide (NO), indicated by the sum of nitrites and nitrates, and vascular growth endothelial growth factor (VEGF) were measured in paw tissues of rats to determine their involvement in the regulation of increased permeability. Pretreatments with AEBO (50 and 150 mg kg⁻¹) prior to serotonin inductions resulted in maximum inhibitions of 56.2% of paw volume, 45.7% of Evans blue dye leakage in the peritoneal vascular permeability model, and 83.9% of leukocyte infiltration in the air-pouch model. 57.2% maximum inhibition of NO and 27% of VEGF formations in rats' paws were observed with AEBO at the dose of 150 mg kg⁻¹. Pharmacological screening of the extract showed significant (P < 0.05) anti-inflammatory activity, indicated by the suppressions of increased vascular permeability and leukocyte infiltration. The inhibitions of these inflammatory events are probably mediated via inhibition of NO and VEGF formation and release.

Abstract
Fruits of Pterodon pubescens Benth have been used traditionally for the treatment of rheumatism, sore throat, and respiratory disorders, and also as anti-inflammatory, analgesic, depurative, tonic, and hypoglycemic agent. The study was aimed at evaluating the anti-inflammatory activity of the hexane fraction of an ethanolic extract of P. pubescens fruits. The oil from P. pubescens fruits was extracted with ethanol and partitioned with hexane. The anti-inflammatory activity was measured with increasing doses of the hexane fraction (FHPp) by using a carrageenan-induced rat model of pleurisy and a rat model of complete Freund's adjuvant-induced arthritis by using an FHPp dose of 250 mg/kg for 21 days. Treatment with an FHPp resulted in anti-inflammatory activity in both models. The results of biochemical, hematological, and histological analyses indicated a significant decrease in glucose, cholesterol, and triglycerides levels (18.32%, 34.20%, and 41.70%, resp.) and reduction in the numbers of total leukocytes and mononuclear cells. The FHPp dose of 1000 mg/kg induced no changes in behavioral parameters, and no animal died. The results of this study extend the findings of previous reports that have shown that administration of extracts and fractions obtained from species of the genus Pterodon exhibits anti-inflammatory activity and lacks toxicity.

Abstract
Relatam-se mortalidades de bovinos nos Estados de Mato Grosso e Mato Grosso do Sul relacionadas ao consumo de folhas de Pterodon emarginatus. Três surtos ocorreram no período de seca na região Centro-Oeste, após a queda de árvores devido a ventos fortes ou após serem derrubadas para aproveitamento da madeira. Morreram 40 bovinos em três diferentes surtos. A intoxicação foi reproduzida com administração de folhas de P. emarginatus; a dose tóxica mínima foi 20g/kg para ovinos e 6g/kg para bovinos. Os sinais clínicos iniciaram-se entre 24 e 72 horas após o consumo da planta. A evolução clínica da doença letal foi de 12 a 36 horas. Os sinais clínicos se caracterizaram por apatia, depressão, andar a esmo, pressão da cabeça contra objetos. Em dois dos surtos, os bovinos que sobreviveram a fase aguda da doença, desenvolveram fotossensibilização. Os principais achados macroscópicos nos casos espontâneos e experimentais foram no fígado; estes se caracterizaram por hepatomegalia e evidenciação do padrão lobular na superfície capsular e de corte. Notaram-se também hemorragias nas serosas abdominais e torácicas. Microscopicamente observou-se necrose coagulativa hepatocelular, que variou de centrolobular a massiva, por vezes associada à congestão e hemorragia; ocorreu também marcada tumefação e vacuolização de hepatócitos na região periacinar. O diagnóstico foi baseado nos dados epidemiológicos, clínicos, patológicos e na reprodução experimental da intoxicação em bovinos e ovinos. Estes achados caracterizam P. emarginatus como planta hepatotóxica de interesse pecuário na região Centro-Oeste do Brasil.

Abstract
BACKGROUND AferBio is a fermented prebiotic food that contains beta-glucans, which are oligosaccharides capable of stimulating the proliferation of beneficial bacteria in the gastrointestinal tract. The aim of this study was to evaluate the possible effects of this functional food on the inflammatory response in rats. METHODS AND RESULTS AferBio (900 mg/kg) inhibited edema formation by 34% compared to the control group. We also observed inhibition of the primary and secondary reactions of inflammation after the injection of Freund's adjuvant in the animals fed AferBio. Daily administration of AferBio for 6 d inhibited the formation of granulomatous tissue by 37%; additionally, inhibition of 31% of neutrophil migration downstream of carrageenan-induced peritonitis was observed. An ulcerogenic potency assay revealed that indomethacin produced a higher number of lesions compared to treatment with AferBio. Anti-inflammatory potency analysis showed that indomethacin inhibited 39% of carrageenan-induced edema but produced a higher number of lesions. However, animals treated with AferBio had areas of hyperemia without ulcerative lesions and 21% of edema was inhibited. CONCLUSION Based on the results obtained in this study, AferBio appears to have anti-inflammatory activity during acute and chronic inflammatory processes.

Chemical composition, antinociceptive and anti-inflammatory effects in rodents of the essential oil of Peperomia serpens (Sw.) Loud. JOURNAL OF ETHNOPHARMACOLOGY 2011; 138:479-486. [PMID: 21971207 DOI: 10.1016/j.jep.2011.09.037] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/09/2011] [Revised: 07/29/2011] [Accepted: 09/20/2011] [Indexed: 05/31/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Peperomia serpens (Piperaceae), popularly known as "carrapatinho", is an epiphyte herbaceous liana grown wild on different host trees in the Amazon rainforest. Its leaves are largely used in Brazilian folk medicine to treat inflammation, pain and asthma. AIM OF THE STUDY This study investigated the effects of essential oil of Peperomia serpens (EOPs) in standard rodent models of pain and inflammation. MATERIALS AND METHODS The antinociceptive activity was evaluated using chemical (acetic acid and formalin) and thermal (hot plate) models of nociception in mice whereas the anti-inflammatory activity was evaluated by carrageenan- and dextran-induced paw edema tests in rats croton oil-induced ear edema, as well as cell migration, rolling and adhesion induced by carrageenan in mice. Additionally, phytochemical analysis of the EOPs has been also performed. RESULTS Chemical composition of the EOPs was analyzed by gas chromatography and mass spectrometry (GC/MS). Twenty-four compounds, representing 89.6% of total oil, were identified. (E)-Nerolidol (38.0%), ledol (27.1%), α-humulene (11.5%), (E)-caryophyllene (4.0%) and α-eudesmol (2.7%) were found to be the major constituents of the oil. Oral pretreatment with EOPs (62.5-500 mg/kg) significantly reduced the writhing number evoked by acetic acid injection, with an ED(50) value of 188.8 mg/kg that was used thereafter in all tests. EOPs had no significant effect on hot plate test but reduced the licking time in both phases of the formalin test, an effect that was not significantly altered by naloxone (0.4 mg/kg, s.c.). EOPs inhibited the edema formation induced by carrageenan and dextran in rats. In mice, EOPs inhibited the edema formation by croton oil as well as the leukocyte and neutrophil migration, the rolling and the adhesion of leukocytes. CONCLUSIONS These data show for the first time that EOPs has a significant and peripheral antinociceptive effect that seems unrelated to interaction with the opioid system. EOPs also displays a significant anti-inflammatory effect in acute inflammation models. This effect seems to be related to components which inhibit the production of several inflammatory mediators. These results support the widespread use of Peperomia serpens in popular medicine to treat inflammation and pain.

Abstract
Inflammation is a complex event linked to tissue damage whether by bacteria, physical trauma, chemical, heat or any other phenomenon. This physiological response is coordinated largely by a variety of chemical mediators that are released from the epithelium, the immunocytes and nerves of the lamina propria. However, if the factor that triggers the inflammation persists, the inflammation can become relentless, leading to an intensification of the lesion. The present work is a literature survey of plant extracts from the South American continent that have been reported to show anti-inflammatory activity. This review refers to 63 bacterial families of which the following stood out: Asteraceae, Fabaceae, Euphorbiaceae, Apocynaceae and Celastraceae, with their countries, parts used, types of extract used, model bioassays, organisms tested and their activity.

Abstract
The crude alcoholic extracts obtained from Pterodon pubescens Benth. seeds are widely used in Brazilian folk medicine as anti-inflammatory, analgesic, anti-rheumatic tonics and depurative preparations. We previously demonstrated the antinociceptive activity on writhing capsaicin, glutamate, and hot-plate tests of two compounds isolated from P. pubescens: geranylgeraniol (C1) and 6α,7β-dihydroxyvouacapan-17β-oate methyl ester (C2). This work is a continuation of the previous study investigating the possible mechanisms of action for compounds C1 and C2, and the differences between them. The present study demonstrated that when administered intraperitoneally (i.p.): i), compounds C1 and C2 produced significant anti-allodynic activity during the acute phase of the Complete Freund's Adjuvant (CFA)-induced persistent pain model; ii) compound C1 produced significant anti-hypernociception activity in the carrageenan-induced pain model; iii) compound C2 presented a significant loss of activity after p-chlorophenylalanine methyl ester hydrochloride (PCPA) [5-HT synthesis inhibitor] treatment, suggesting that the mechanisms of action could be related to either the synthesis or release of serotonin; iv) compound C1 presented a significant loss of activity after ondansetron (5-HT(3) receptor antagonist) treatment suggesting activity upon 5-HT(3) serotonin receptors; v) compound C1 presented a significant loss of activity after efaroxan (mixed I(1) imidazoline/α(2)-adrenoceptor antagonist) treatment suggesting the participation of this compound upon imidazoline I(1) receptors; and vi) both compounds C1 and C2 did not appear to exert their activity via 5-HT(1A), 5-HT(2A), imidazoline I(2), α(2)-adrenoceptor, nitric oxide, GABA(A), acetylcholine muscarinic, and nicotinic receptors when evaluated in acetic acid-induced nociception.

Abstract
ETHNOPHARMACOLOGICAL IMPORTANCE Many species of plants in the Brazilian cerrado (savanna) are widely used in ethnomedicine. However, the safety and effectiveness of medicinal plants used in communities with little or no access to manufactured drugs should be evaluated. AIM OF THE STUDY Evaluate the antimicrobial and cytotoxic activities of extracts from eight plant species, obtained using Brazilian cachaça as the extractor liquid. MATERIALS AND METHODS The extracts were tested against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, Candida parapsilosis, promastigote forms of Leishmania amazonensis, and poliovirus. In addition, cytotoxic activity was assayed in Vero cells and in human erythrocytes. RESULTS The plant species Curatella americana, Sclerolobium aureum, and Plathymenia reticulata showed the best activity against yeasts, especially the crude extract of C. americana and its ethyl-acetate fraction. Kielmeyera lathrophyton showed a minimum inhibitory concentration of 250 μg/ml against S. aureus, and was inactive against gram-negative bacteria. The extract obtained from Annona coriacea showed the best activity against the promastigote forms of Leishmania amazonensis (IC(50)=175 μg/ml). Only C. americana showed potential for antipoliovirus activity. The concentrations of the crude extracts that showed toxicity to VERO cells had CC(50) between 31 and 470 μg/ml, and the lyophilized Brazilian cachaça showed a CC(50) of 307 μg/ml. None of the extracts showed toxicity against human erythrocytes. CONCLUSIONS Among the plant species studied, C. americana proved to be effective against microorganisms, especially as an antifungal. The results will help in the search for alternative drugs to be used in pharmacotherapy, and will contribute to establish safe and effective use of phytomedicines in the treatment of infectious diseases.

Abstract
The plant of the genus Pterodon (Fabaceae, Leguminosae), commonly known as 'sucupira' or 'faveira', are disseminated throughout the central region of Brazil and has frequently been used in popular medicine for its anti-rheumatic, analgesic, and anti-inflammatory properties. In recent years, interest in these plants has increased considerably. The biological effects of different phytoextracts and pure metabolites have been investigated in several experimental models in vivo and in vitro. The literature describes flavonoids, triterpene and steroids, while one paper presented studies with proteins isolated from the genus. This review provides an overview of phytochemical and pharmacological research in Pterodon, showing the main chemical compounds studied to date, and focusing on the relationship between these molecules and their biological activity. Furthermore, this study paves the way for more in-depth investigation, isolation and characterization of the molecules of this plant genus.

Abstract
Abstract
Objectives
The objective of this work was to investigate the antiulcerogenic and anti-inflammatory activities of the essential oil from Pterodon emarginatus seeds.
Methods
The following tests were used: ulcers induced by ethanol, indometacin and HCl/ethanol, and pleurisy induced by carrageenan in Swiss albino rats. The rats were treated by the oral route with essential oil of P. emarginatus seeds.
Key findings
The essential oil at 100, 300 and 500 mg/kg exhibited significant protection against ulcers induced by ethanol, indometacin and HCl/ethanol (P < 0.001). The essential oil caused a marked reduction in the exudate volume and inhibited leucocyte and neutrophil influx (P < 0.05) in carrageenan-induced pleurisy. Moreover, the essential oil significantly decreased nitric oxide (NO) and interleukin-1 (IL-1) levels, without affecting tumour necrosis factor-α production.
Conclusions
The results demonstrated the marked antiulcerogenic and anti-inflammatory effects of the essential oil from P. emarginatus, which are, at least in part, a consequence of NO and IL-1 modulation. P. emarginatus or its constituents might represent new therapeutic options to treat gastric ulcers and inflammatory diseases.

Abstract
Background Pterodon pubescens Benth seeds are commercially available in the Brazilian medicinal plant street market. The crude alcoholic extracts of this plant are used in folk medicine as anti-inflammatory, analgesic, and anti-rheumatic preparations. The aim of this study was to evaluate the contribution of geranylgeraniol (C1) and 6α, 7β-dihydroxyvouacapan-17β-oate methyl ester (C2) isolated from Pterodon pubescens Benth. to the antinociceptive activity of the crude extract. Results Compounds C1 and C2 demonstrated activity against writhing with intraperitoneal (i.p.) and oral (p.o.) routes, capsaicin (i.p. and p.o.), glutamate (i.p.), and in the hot-plate (p.o.) tests, demonstrating their contribution to the antinociceptive activity of crude Pterodon pubescens Benth extracts. The observed activity of compounds C1 and C2 may be related to vanilloid receptors VR1, and/or glutamate peripheral receptors. In hot-plate model, the antinociceptive activity was maintained when naloxone chloride (opioid antagonist) was administered prior to treatment with compounds suggesting that C1 and C2 (p.o.) do not exert their antinociceptive effects in the hot-plate test via opioid receptors. The findings presented herein also suggest that compounds within the crude Pterodon pubescens Benth. extract may exert a synergistic interactive effect, since the crude extract (300 mg.kg-1) containing lower concentrations of compounds C1 (11.5%- 34.6 mg. kg-1) and C2 (1.5% - 4.7 mg.kg-1) gave statistically the same effect to the pure compounds when tested separately (C1 = C2 = 300 mg.kg-1) in writhing experimental model with p.o. administration. Further studies will be undertaken to establish more specifically the mechanisms of action for compounds C1 and C2. Possible synergistic interactions will be evaluated employing the Isobole method. Conclusion These results allowed us to establish a relationship between the popular use of Pterodon pubescens seeds for pain relief and the activity of two major compounds isolated from this species which demonstrated antinociceptive activity. Various "in vivo" experimental models corroborate the folk use of this species for different pain and inflammation disorders.

Abstract
This work describes the synthesis and anti-inflammatory properties of a pentadienone derivative, HB2. The treatment with HB2 produced anti-oedematogenic, anti-inflammatory and antinociception without change locomotors performance. Finally, HB2 reduced the nitric oxide and prostaglandin E(2) production on RAW 264.7 cells stimulated with LPS without changing the cell viability. Taken together, our results show, for the first time, that HB2 can modulate the inflammatory response when administered to mice.

Abstract
The antioxidant activity of flavonoids is believed to increase when they are coordinated with transition metal ions. However, the literature on this subject is contradictory and the outcome seems to largely depend on the experimental conditions. In order to understand the contribution of the metal coordination and the type of interaction between a flavonoid and the metal ion, in this study a new metal complex of Cu (II) with naringin was synthesized and characterized by FT-IR, UV-VIS, mass spectrometry (ESI-MS/MS), elemental analysis and 1H-NMR. The results of these analyses indicate that the complex has a Cu (II) ion coordinated via positions 4 and 5 of the flavonoid. The antioxidant, anti-inflammatory and antimicrobial activities of this complex were studied and compared with the activity of free naringin. The Naringin-Cu (II) complex 1 showed higher antioxidant, anti-inflammatory and tumor cell cytotoxicity activities than free naringin without reducing cell viability.

Abstract
Austroplenckia populnea (Reiss) Lund is a Brazilian plant from "cerrado", which belongs to Celastraceae family, popularity know as "marmelinho-do campo, mangabeira-brava, mangabarana, vime and maria-mole". This plant is used in folk medicine to treat dysenteries and inflammatory disorders, such as rheumatism. Austroplenckia populnea bark hydroalcoholic crude extract, and its hexane, chloroform and ethyl acetate fractions, obtained by partition, as well as the isolated populnoic acid were investigated for their anti-inflammatory (carrageenan, dextran and histamine-induced rat paw oedema, histamine-induced increase in vascular permeability, and granulomatous tissue induction) and analgesic activities (writhing and hot plate tests). The ED(50) (oral) of the crude extract for the inhibition of carragenan-induced rat paw oedema assay was determined to be 200 mg/kg, which was also used in the assays with the extract and its fractions in all other experiments. Populnoic acid was administered in the dose of 50 mg/kg. Crude extract, hexane and chloroform fractions (200 mg/kg), and indomethacin (10 mg/kg) inhibited significantly (p<0.05) the formation of the carrageenan-induced rat paw oedema, measured in third hour of experiment (peak of oedema formation) by 43.2%, 37.3%, 31.1% and 59.3%, respectively. There was a significant reduction (p<0.05) in dextran-induced rat paw oedema in all groups, while in the assay using histamine as the oedematogenic agent, only the groups treated with populnoic acid (50 mg/kg) and cyproheptadine (10 mg/kg) displayed significant reduction (p<0.05). The populnoic acid and cyproheptadine reduced the peak of oedema formation (1st hour) by 41.3% and 34.7%, respectively. Only for the groups treated with populnoic acid (50 mg/kg) and cyproheptadine (10 mg/kg) it was observed a significant (p<0.05) reduction in histamine-induced increase in vascular permeability (44.8% and 80.3%, respectively). Granulomatous tissue formation was significantly inhibited (p<0.05) by both hexane fraction (46.0%) and dexamethasone (66.2%). In the analgesic assays, the crude extract and its hexane and chloroform fractions, as well as indomethacin diminished significantly the number of writhings (p<0.05) by 69.6%, 47.2%, 44.8% and 62.8%, respectively. On the other hand, none assayed sample displayed significant result in the hot plate test. Based on the obtained results it is suggested that extracts of Austroplenckia populnea bark and populnoic acid display anti-inflammatory activity, supporting its folkloric use to treat inflammatory disorders.

Gastric antiulcer and anti-inflammatory activities of the essential oil from Casearia sylvestris Sw. JOURNAL OF ETHNOPHARMACOLOGY 2005; 101:191-6. [PMID: 15994044 DOI: 10.1016/j.jep.2005.04.020] [Citation(s) in RCA: 66] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/06/2004] [Revised: 04/08/2005] [Accepted: 04/27/2005] [Indexed: 05/03/2023]
Abstract
To investigate the antiulcer and antiinflammatory activities of the essential oil from Casearia sylvestris leaves (EOCS) the following tests were used: rat paw edema, granulomatous tissue test, vascular permeability, writhing test, gastric ulcer stress-induced and evaluation of gastric secretion (pylorus ligation test). The total yield of EOCS was 2.5% with LD50 of 1100 mg/kg in mouse. The major compounds identified using gas chromatography were caryophyllene, thujopsene, alfa-humulene, beta-acoradiene, germacrene-d, bicyclogermacrene, calamenene, germacrene B, spathulenol and globulol. The EOCS orally administered to the rats at 125 mg/kg resulted 36% of inhibition in carrageenan-induced edema in the rat paw assay (p<0.05, Student's t-test). However, both rat paw edema dextran-induced and vascular permeability assay using histamine showed no significant inhibition. Mice submitted to the writhing test using acetic acid presented 58% and 56% of inhibition in writhes with EOCS and indomethacin, respectively. Furthermore, EOCS inhibited 90% of stress-induced gastric ulcer, while cimetidine inhibited 70% (p<0.05, Student's t-test). The volume of gastric secretion in the group treated with EOCS was greater than the group treated with cimetidine. The EOCS also showed no changes related to H+ levels in the gastric secretion. With the overall results obtained in this study the authors suggest an anti-inflammatory activity for the EOCS of Casearia sylvestris beyond its anti-ulcer activity.
