[PMID: 38611904 PMCID: PMC11013677 DOI: 10.3390/molecules29071625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Revised: 03/31/2024] [Accepted: 04/01/2024] [Indexed: 04/14/2024] Open
Abstract
In recent years, caffeic acid and its derivatives have received increasing attention due to their obvious physiological activities and wide distribution in nature. In this paper, to clarify the status of research on plant-derived caffeic acid and its derivatives, nuclear magnetic resonance spectroscopy data and possible biosynthetic pathways of these compounds were collected from scientific databases (SciFinder, PubMed and China Knowledge). According to different types of substituents, 17 caffeic acid and its derivatives can be divided into the following classes: caffeoyl ester derivatives, caffeyltartaric acid, caffeic acid amide derivatives, caffeoyl shikimic acid, caffeoyl quinic acid, caffeoyl danshens and caffeoyl glycoside. Generalization of their 13C-NMR and 1H-NMR data revealed that acylation with caffeic acid to form esters involves acylation shifts, which increase the chemical shift values of the corresponding carbons and decrease the chemical shift values of the corresponding carbons of caffeoyl. Once the hydroxyl group is ester, the hydrogen signal connected to the same carbon shifts to the low field (1.1~1.6). The biosynthetic pathways were summarized, and it was found that caffeic acid and its derivatives are first synthesized in plants through the shikimic acid pathway, in which phenylalanine is deaminated to cinnamic acid and then transformed into caffeic acid and its derivatives. The purpose of this review is to provide a reference for further research on the rapid structural identification and biofabrication of caffeic acid and its derivatives.

Alibertia patinoi (Cuatrec.) Delprete & C.H.Perss. (Borojó): food safety, phytochemicals, and aphrodisiac potential. SN APPLIED SCIENCES 2023.

Abstract
AbstractAlthough the western discovery of borojó [Alibertia patinoi Cuatrec. (Delprete & C.H.Perss.)] is as recent as 1948, its several traditional uses in gastronomy and medicine, and its fame as an aphrodisiac are long standing and strong: the “love juice” extracted from it is very appreciated in Colombia, Ecuador, and Panama. Its medicinal potential, though, is far wider. This literature review aims to summarize the knowledge about the fruit, its ethnomedical uses, its biological activity and phytochemical composition, to validate ethnomedical claims and to help envision future lines of research. Borojó extracts have confirmed antimicrobial and antioxidant, and potential anticancer activities, which can be at least partially explained by its phytochemical composition -compounds isolated and identified through Gas Chromatography, High Performance Liquid Chromatography and spectroscopic and spectrometric techniques- rich in phenolic compounds, some of which, for example oleuropein, chlorogenic acid and rutin, possess proven biological activity. There is potential for borojó products as a source of bioactive natural products, which have not been exhaustively identified despite phytochemical screenings that show the presence of unstudied compound families: terpenoids, alkaloids, steroids; and functional alimentary products. Although its aphrodisiac properties have not been confirmed, several compounds with confirmed aphrodisiac activity in other species, mainly flavonoids, are also found in borojó. These, coupled with its nutritional profile and perhaps compounds yet unidentified, could validate the claim.

Abstract
Leishmaniasis is a neglected disease that affects millions of people, mostly in developing countries. Although this disease has a high impact on public health, there are few drug options to treat the different leishmaniasis forms. Additionally, these current therapies have various adverse effects, including gastrointestinal disturbances, headache, pancreatitis, and hepatotoxicity. Thus, it is essential to develop new drug prototypes to treat leishmaniasis. Accordingly, the present study aimed to evaluate the leishmanicidal activity of Morita-Baylis-Hillman adducts and their O-acetylates, carboxylic acid derivatives, and acid and ester derivatives of 2-methyl-phenylpropanoids against Leishmania chagasi. Initially, we evaluated the cytotoxicity of 16 derivatives (1-16G) against J774A.1 macrophages. Eight derivatives (2G, 4G, 5G, 7G, 9G, 10G, 13G, and 15G) showed no cytotoxicity at up to the maximum concentration tested (100 μM). When evaluated for antileishmanial effect against promastigote forms, 1G, 6G, 8G, 10G, 11G, 13G, 14G, 15G, and 16G displayed significant toxicity compared to the control (0.1% DMSO). Additionally, the compounds 1G, 5G, 7G, 9G, 11G, 13G, 14G, and 16G reduced macrophage infection by amastigotes. Thus, we conclude that these derivatives have antileishmanial effects, particularly 1G, which showed activity against promastigotes and amastigotes, and low toxicity against macrophages.

Abstract
Leishmaniasis still stands as one of the most prevalent neglected tropical diseases in the least developed and emerging countries. The recommended therapeutic arsenal to treat leishmaniasis is characterized by several shortcomings, and resistance has already been reported. Hence, this dramatic background highlights the pressing need to develop novel, affordable, and safe antileishmanial drugs. Multiple classes of natural compounds have been reported to possess antileishmanial activity. Among these classes, iridoids stand out as a special type of monoterpenoids with diverse biological properties-including their antileishmanial potential. This review aims to discuss the available literature between 1991 and 2020 related to the antileishmanial activity of the iridoid class. Throughout the past decades, various investigations attributed antileishmanial action to assorted iridoid types, including inhibitory potential towards validated drug targets and immunomodulatory activity. The latter deserves special attention due to the ability of some iridoids to improve the host's immune response against parasites. It opens the possibility of iridoids become adjuncts in leishmaniasis treatments by improving the efficacy of currently employed drugs. Furthermore, the present study intends to provide a convenient visual representation of which iridoids and Leishmania spp. species have been most investigated as a guide for further researches.

Abstract
Coronavirus (CoV) is a positive RNA genome virus causing a global panic nowadays. Tecoma is a medicinally-valuable genus in the Bignoniaceae family, with some of its species exhibiting anti-HIV activity. This encouraged us to conduct an in silico exploration of some phytocompounds in Tecoma species cultivated in Egypt, namely Tecoma capensis and its four varieties i.e. yellow, harmony, pink and red, T. grandiflora Loisel., T. radicans L., and one hybrid i.e. Tecoma × smithii W. Watson. LC/MS-based metabolite profiling of the studied Tecoma plants resulted in the dereplication of 12 compounds (1–12) belonging to different phytochemical classes viz. alkaloids, iridoids, flavonoids and fatty acid esters. The in silico inhibitory action of these compounds against SARS-CoV-2 spike protein C-terminal domain in complex with human ACE2 was assessed via molecular docking. Succinic acid decyl-3-oxobut-2-yl ester (10), a fatty acid ester, possessed the best binding affinity (−6.77 kcal mol−1), as compared to hesperidin (13) (−7.10 kcal mol−1). In silico exploration of 12 Tecoma phytocompounds that could serve as potential inhibitors of SARS-CoV entry to host cells.![]()

Abstract
BACKGROUND Leishmaniasis reaches millions of people around the world. The control of the disease is difficult due to the restricted access to the diagnosis and medication, and low adherence to the treatment. Thus, more efficient drugs are needed and natural products are good alternatives. Iridoids, natural products with reported leishmanicidal activity, can be exploited for the development of anti- Leishmania drugs. The aim of this study was to isolate and to investigate the in vitro activity of iridoids against Leishmania amazonensis and to compare the activity in silico of these compounds with those reported as active against this parasite. METHODS Iridoids were isolated by chromatographic methods. The in vitro activity of asperuloside (1) and geniposide (2) from Escalonia bifida, galiridoside (3) from Angelonia integerrima and theveridoside (4) and ipolamiide (5) from Amphilophium crucigerum was investigated against promastigote forms of Leishmania amazonensis. Molecular modeling studies of 1-5 and iridoids cited as active against Leishmania spp. were performed. RESULTS Compounds 1-5 (5-100 µM) did not inhibit the parasite survival. Physicochemical parameters predicted for 1-5 did not show differences compared to those described in literature. The SAR and the pharmacophoric model confirmed the importance of maintaining the cyclopentane[C]pyran ring of the iridoid, of oxygen-linked substituents at the C1 and C6 positions and of bulky substituents attached to the iridoid ring to present leishmanicidal activity. CONCLUSION The results obtained in this study indicate that iridoids are a promising group of secondary metabolites and should be further investigated in the search for new anti-Leishmania drugs.

Abstract
Phenylethanoid glycosides (PhGs) are generally water-soluble phenolic compounds that occur in many medicinal plants. Until June 2020, more than 572 PhGs have been isolated and identified. PhGs possess antibacterial, anticancer, antidiabetic, anti-inflammatory, antiobesity, antioxidant, antiviral, and neuroprotective properties. Despite these promising benefits, PhGs have failed to fulfill their therapeutic applications due to their poor bioavailability. The attempts to understand their metabolic pathways to improve their bioavailability are investigated. In this review article, we will first summarize the number of PhGs compounds which is not accurate in the literature. The latest information on the biological activities, structure-activity relationships, mechanisms, and especially the clinical applications of PhGs will be reviewed. The bioavailability of PhGs will be summarized and factors leading to the low bioavailability will be analyzed. Recent advances in methods such as bioenhancers and nanotechnology to improve the bioavailability of PhGs are also summarized. The existing scientific gaps of PhGs in knowledge are also discussed, highlighting research directions in the future.

Abstract
In traditional Arabian medicine, the Rhus tripartita plant (family Anacardiaceae) has been used to treat inflammatory conditions. Although Rhus extracts have been reported for their cardioprotective effects, information regarding their active principle compounds remains insufficient. The present investigation was aimed at determining the antioxidant chemical constituents of the methanolic extract of R. tripartita stem bark and evaluating their ability to ameliorate methylglyoxal-induced endothelial cell apoptosis. Ten flavonoid compounds (1–10) were isolated and identified using DPPH radical scavenging bioassay-guided chromatographic separation. A new proanthocyanidin (rhuspartin) (1) was isolated and identified as 3,5,13,14-flavantetrol-(4β→8)-catechin, using extensive spectroscopic data and high resolution-mass spectrometry. Among the compounds (1, 5, 7–10) tested for toxicity toward cultured endothelial cells (HUVECs), the non-cytotoxic compounds 1 and 7 evinced cytoprotective potential that reversed the methylglyoxal-induced apoptosis (by 62% and 64%, respectively) through downregulation of caspase 3/7.

Abstract
Piplartine is an alkamide found in different Piper species and possesses several biological activities, including antiparasitic properties. Thus, the aim of the present study was to evaluate a series of 32 synthetic piplartine analogues against the Leishmania amazonensis promastigote forms and establish the structure-activity relationship and 3D-QSAR of these compounds. The antileishmanial effect of the compounds was determined using the MTT method. Most compounds were found to be active against L. amazonensis. Among 32 assayed derivatives, compound (E)-(−)-bornyl 3-(3,4,5-trimethoxyphenyl)-acrylate exhibited the most potent antileishmanial activity (IC50 = 0.007 ± 0.008 μM, SI > 10), followed by benzyl 3,4,5-trimethoxybenzoate (IC50 = 0.025 ± 0.009 μM, SI > 3.205) and (E)-furfuryl 3-(3,4,5-trimethoxyphenyl)-acrylate (IC50 = 0.029 ± 0.007 μM, SI > 2.688). It was found that the rigid substituents contribute to increasing antiparasitic activity against L. amazonensis promastigotes. The presence of the unsaturated heterocyclic substituent in the phenylpropanoid chemical structure (furfuryl group) resulted in a bioactive derivative. Molecular simplification of benzyl 3,4,5-trimethoxybenzoate by omitting the spacer group contributed to the bioactivity of this compound. Furthermore, bornyl radical appears to be important for antileishmanial activity, since (E)-(−)-bornyl 3-(3,4,5-trimethoxyphenyl)-acrylate exhibited the most potent antileishmanial activity. These results show that some derivatives studied would be useful as prototype molecules for the planning of new derivatives with profile of antileishmanial drugs.

Abstract
New iridoid glycoside derivatives from durantoside I, the latter from the dried flowers and leaves of Citharexylum spinosum, were synthesized by variously modifying a sugar moiety by silylation or acetylation and/or removal of cinnamate group at C-7 position and subsequent screening for comparative cytotoxicity against several cancer cell lines. Addition of alkylsilane to durantoside I and removal of cinnamate group were most effective in improving cytotoxicity.

Acyclic Sesquiterpenes from the Fruit Pericarp of Sapindus saponaria Induce Ultrastructural Alterations and Cell Death in Leishmania amazonensis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 2017:5620693.

Abstract
Previous studies reported antiprotozoal activities of Sapindus saponaria L. The aim of this work was the evaluation of antileishmanial activity and mechanism of action of extract and fractions of S. saponaria L. Hydroethanolic extract (EHA) obtained from fruit pericarps was fractionated using solid-phase extraction in a reversed phase, resulting in fractions enriched with saponins (SAP fraction) and acyclic sesquiterpene oligoglycosides (OGSA fraction). The activities of EHA, SAP, and OGSA were evaluated by antiproliferative assays with promastigote and intracellular amastigote forms. Cytotoxicity on macrophages and hemolytic activity were also analyzed. Morphological and ultrastructural changes in Leishmania amazonensis promastigotes were evaluated by electron microscopy. Flow cytometry was used to investigate mitochondrial dysfunction and phosphatidylserine exposure. OGSA was more selective for parasites than mammalian J774A1 macrophage cells, with selectivity indices of 3.79 and 7.35, respectively. Our results showed that only the OGSA fraction did not present hemolytic activity at its IC50 for promastigote growth. Electron microscopy revealed changes in parasite flagellum, cell body shape, and organelle size, mainly mitochondria. Flow cytometry analysis indicated mitochondrial membrane and cell membrane dysfunction. OGSA showed antileishmanial activity, resulting in several changes to protozoa cells, including mitochondrial depolarization and early phosphatidylserine exposure, suggesting a possible apoptotic induction.

Abstract
During Trypanosoma cruzi infection, oxidative stress is considered a contributing factor for dilated cardiomyopathy development. In this study, the effects of astaxanthin (ASTX) were evaluated as an alternative drug treatment for Chagas disease in a mouse model during the acute infection phase, given its anti-inflammatory, immunomodulating, and anti-oxidative properties. ASTX was tested in vitro in parasites grown axenically and in co-culture with Vero cells. In vivo tests were performed in BALB/c mice (4-6 weeks old) infected with Trypanosoma cruzi and supplemented with ASTX (10 mg/kg/day) and/or nifurtimox (NFMX; 100 mg/kg/day). Results show that ASTX has some detrimental effects on axenically cultured parasites, but not when cultured with mammalian cell monolayers. In vivo, ASTX did not have any therapeutic value against acute Trypanosoma cruzi infection, used either alone or in combination with NFMX. Infected animals treated with NFMX or ASTX/NFMX survived the experimental period (60 days), while infected animals treated only with ASTX died before day 30 post-infection. ASTX did not show any effect on the control of parasitemia; however, it was associated with an increment in focal heart lymphoplasmacytic infiltration, a reduced number of amastigote nests in cardiac tissue, and less hyperplasic spleen follicles when compared to control groups. Unexpectedly, ASTX showed a negative effect in infected animals co-treated with NFMX. An increment in parasitemia duration was observed, possibly due to ASTX blocking of free radicals, an anti-parasitic mechanism of NFMX. In conclusion, astaxanthin is not recommended during the acute phase of Chagas disease, either alone or in combination with nifurtimox.

Antinociceptive activity and mechanism of action of hydroalcoholic extract and dichloromethane fraction of Amphilophium crucigerum seeds in mice. JOURNAL OF ETHNOPHARMACOLOGY 2017; 195:283-297. [PMID: 27864110 DOI: 10.1016/j.jep.2016.11.032] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/12/2016] [Revised: 10/16/2016] [Accepted: 11/15/2016] [Indexed: 06/06/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The medicinal plant generally known as monkey's comb (Amphilophium crucigerum) has been popularly described for the treatment of neuropathic and inflammatory pain, specially seeds preparations. AIM OF THE STUDY The goal of the present study was to evaluate the antinociceptive effect of the crude extract (Crd) and dichloromethane fraction (Dcm) of A. crucigerum seeds, and investigate the involvement of transient receptor potential vanilloid 1 (TRPV1) receptor in this effect. MATERIALS AND METHODS Male Swiss mice were used in this study. The effects of Crd and Dcm was tested on capsaicin-induced Ca2+ influx or the specific binding of [3H]-resiniferatoxin. Moreover, after treatment with Crd or Dcm, animals were exposed to acute pain (hot water tail-flick and capsaicin intraplantar test) or chronic pain models (injection of complete Freund's adjuvant or partial ligation of the sciatic nerve). Acute adverse effects were also noted: locomotor activity, corporal temperature, hepatic or renal damage, gastrointestinal transit alteration, and ulcerogenic activity. RESULTS The oral administration of Crd or Dcm resulted in an antinociceptive effect in the hot water tail-flick (48°C) and capsaicin intraplantar tests. Furthermore, these preparations exhibited antinociceptive and anti-inflammatory effects in a chronic inflammatory pain model, and antinociceptive effects in a neuropathic pain model. Moreover, Crd and Dcm reduced capsaicin-induced Ca2+ influx and diminished the [3H]-resiniferatoxin specific binding to spinal cord membranes. Acute adverse events were not found with Crd or Dcm administration. CONCLUSION In conclusion, our results support the analgesic effect of A. crucigerum and suggest the presence of compounds that may act as TRPV1 antagonists.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tecoma stans is traditionally used by several ethnical groups in Mexico and Central America to treat diabetes. This species is mentioned in the majority of the ethnopharmacological studies compiled in Mexico focused in medicinal plants used as anti-diabetic treatment. AIM OF THE STUDY Recently, this plant was found to display a high level of pancreatic lipase inhibitory activity, in addition to the several action mechanisms already described. Here we show the phytochemical and in vitro pharmacological characterization of some of the compounds responsible for the antilipase activity. MATERIALS AND METHODS Starting with a hydroalcoholic extract, fractions were obtained by liquid-liquid separation and successive processes of column chromatography purifications. Lipase inhibitory activity was measured employing a spectrophotometric analysis. For structural elucidation (1)H and (13)C NMR experiments were used. HPLC was used to quantify and confirm the identity of the bioactive compounds. RESULTS Bio-guided chemical purification of the hydroalcoholic extract produced an organic fraction (ethyl acetate, TsEA), flavone fractions (TsC1F13), (TsC1F15), (TsC1F16) and isolated compounds (chrysoeriol, apigenin, luteolin, and verbascoside) with the capability to inhibit the activity of pancreatic lipase. The most active fraction (TsC2F6B) was constituted by a mixture of Chrysoeriol (5,7-dihydroxy-2-[4-hydroxy-3-methoxyphenyl]chromen-4-one, 96% ) and Apigenin (4%). This flavone mixture displayed a percentage of inhibition of 85% when it was eavaluated at 0.25mg/mL. Luteolin and chrysoeriol produced a noncompetitive and mixed inhibition with values of IC50=63 and 158µM respectively. The content of chrysoeriol was also quantified in the hydroalcoholic extract (TsHAE) and organic fraction (TsEA) as 1% and 7% respectively. All of this confirms that high proportion of both flavones produce an increase of the biological activity due to they show the highest inhibition of lipase enzyme in a concentration dependant way. CONCLUSIONS These results evidence that the medicinal use of T. stans could be in part because of its lipase inhibitory activity allowing to adapt the administration of this plant before meals. Also this data could help to develop a novel phytopharmaceutical drug (standardized in luteolin, chrysoeriol, and apigenin) auxiliary for the Type 2 Diabetes mellitus.

Abstract
A radical-scavenging, guided phytochemical study of the latex of Calotropis Procera afforded five lignans (1-5), including a new one (4). The structural determination was accomplished using 1D- and 2D-NMR, high-resolution electrospray ionization mass spectrometry (HRESIMS), and correlation with known compounds. Among the isolated compounds, acylated lignans (3-5) showed stronger antioxidant activity than non-acylated derivatives (1,2). Anti-inflammatory activity was evaluated by determining the inhibitory potential against 5- and 15-lipoxygenase enzymes. The highest anti-inflammatory activity was observed in compound 4, with IC50s values of 7.6 µM and 2.7 µM against 5-LOX and 15-LOX, respectively.

Abstract
The polar hydroethanolic extract from Selaginella sellowii(SSPHE)
has been previously proven active on intracellular amastigotes (in vitro test) and
now was tested on hamsters infected with Leishmania (Leishmania)
amazonensis (in vivo test). SSPHE suppressed a 100% of the parasite load
in the infection site and draining lymph nodes at an intralesional dose of 50
mg/kg/day × 5, which was similar to the results observed in hamsters treated with
N-methylglucamine antimonate (Sb) (28 mg/Kg/day × 5). When orally
administered, SSPHE (50 mg/kg/day × 20) suppressed 99.2% of the parasite load in
infected footpads, while Sb suppressed 98.5%. SSPHE also enhanced the release of
nitric oxide through the intralesional route in comparison to Sb. The chemical
fingerprint of SSPHE by high-performance liquid chromatography with diode-array
detection and tandem mass spectrometry showed the presence of biflavonoids and high
molecular weight phenylpropanoid glycosides. These compounds may have a synergistic
action in vivo. Histopathological study revealed that the intralesional treatment
with SSPHE induced an intense inflammatory infiltrate, composed mainly of mononuclear
cells. The present findings reinforce the potential of this natural product as a
source of future drug candidates for American cutaneous leishmaniasis.

Abstract
An essential requirement for the evolution of early eukaryotic life was the development of effective means to protect against metabolic oxidative stress and exposure to environmental toxicants. In present-day mammals, the master transcription factor Nrf2 regulates basal level homeostasis and inducible expression of numerous detoxifying and antioxidant genes. To examine early evolution of the Keap1-Nrf2 pathway, we present bioinformatics analyses of distant homology of mammalian Keap1 and Nrf2 proteins across the Kingdoms of Life. Software written for this analysis is made freely available on-line. Furthermore, utilizing protein modeling and virtual screening methods, we demonstrate potential for Nrf2 activation by competitive inhibition of its binding to Keap1, specifically by UV-protective fungal mycosporines and marine mycosporine-like amino acids (MAAs). We contend that coevolution of Nrf2-activating secondary metabolites by fungi and other extant microbiota may provide prospective compound leads for the design of new therapeutics to target activation of the human Keap1-Nrf2 pathway for treating degenerative diseases of ageing.

Abstract
OBJECTIVE To isolate and identify chemical constituents with antioxidant and lipoxygenase inhibitory effects of the ethanolic extract of Simmondsia chinensis (Jojoba) leaves. METHODS The alcoholic extract was subjected to successive solvent fractionation. The antioxidant active fractions (chloroform, ethyl acetate and aqueous fractions) were subjected to a combination of different chromatographic techniques guided by the antioxidant assay with DPPH. The structures of the isolated compounds were elucidated on the basis of spectroscopic evidences and correlated with known compounds. The antioxidant activity was assessed quantitively using DPPH and β-carotene methods. The inhibitory potential against enzyme lipoxygenase was assessed on soybean lipoxygenase enzyme. RESULTS Ten flavonoids and four lignans were isolated. Flavonoid aglycones showed stronger antioxidant and lipoxygenase inhibitory effects than their glycosides. Lignoid glycosides showed moderate to weak antioxidant and lipoxygenase inhibitory effects. CONCLUSIONS A total of 14 compounds were isolated and identified from Simmondsia chinensis; 12 of them were isolated for the first time. This is the first report that highlights deeply on the phenolic content of jojoba and their potential biological activities and shows the importance of this plant as a good source of phenolics in particular the flavonoid content.

Abstract
Eight compounds including four caffeoyl phenylpropanoid glycosides, jasnervosides A-D (1-4), one monoterpenoid glycoside, jasnervoside E (5), and three secoiridoid glycosides, jasnervosides F-H (10-12), were isolated from the stems of Jasminum nervosum Lour. (Oleaceae), along with four known compounds, poliumoside (6), verbascoside (7), α-l-rhamnopyranosyl-(1→3)-O-(α-l-rhamnopyranosyl(1→6)-1-O-E-caffeoyl-β-d-glucopyranoside (8), and jaspolyanthoside (9). Their structures were elucidated on the basis of their physicochemical and spectroscopic properties. Compounds 1, 2, 4 and 11 displayed potent antioxidant activities in the DPPH assay, while 2 and 3 displayed good activities against LPS-induced TNF-α and IL-1β production in BV2 cells. Compounds 1-5 and 10-12 were evaluated for their cytotoxic activities against three human cancer cell lines (A-549, Bel-7402, and HCT-8), but none displayed significant activity.

Abstract
Prunus tomentosa seeds were researched for antioxidant and anti-inflammatory constituents. By activity-guided fractionation of P. tomentosa seed extract, six new dihydrobenzofuran neolignans, prunustosanans AI-IV (1-4) and prunustosanansides AI and AII (5 and 6), together with 10 known compounds (7-16) were isolated from bioactive fraction. The structures were determined by spectroscopic analyses, especially NMR, HRESIMS, and CD spectra. The antioxidant activity was greatest for 5, 10, and 12 against DPPH radical and for 8, 9, and 13 against ABTS radical. Moreover, compounds 7 and 11 exhibited much stronger inhibitory activity on nitric oxide (NO) production in murine microglia BV-2 compared with positive control minocycline (IC50 = 19.7 ± 1.5 μM). The results show that P. tomentosa seeds can be regarded as a potential source of antioxidants and inflammation inhibitors.

Abstract
The high mutation rate of RNA viruses has resulted in limitation of vaccine effectiveness and increased emergence of drug-resistant viruses. New effective antivirals are therefore needed to control of the highly mutative RNA viruses. The n-butanol fraction of the stem bark of Mangifera indica exhibited inhibitory activity against influenza neuraminidase (NA) and coxsackie virus 3C protease. Bioassay guided phytochemical study of M. indica stem bark afforded two new compounds including one benzophenone C-glycoside (4) and one xanthone dimer (7), together with eleven known compounds. The structures of these isolated compounds were elucidated on the basis of spectroscopic evidences and correlated with known compounds. Anti-influenza and anti-coxsackie virus activities were evaluated by determining the inhibition of anti-influenza neuraminidase (NA) from pandemic A/RI/5+/1957 H2N2 influenza A virus and inhibition of coxsackie B3 virus 3C protease, respectively. The highest anti-influenza activity was observed for compounds 8 and 9 with IC50 values of 11.9 and 9.2μM, respectively. Compounds 8 and 9 were even more potent against coxsackie B3 virus 3C protease, with IC50 values of 1.1 and 2.0μM, respectively. Compounds 8 and 9 showed weak cytotoxic effect against human hepatocellular carcinoma and human epithelial carcinoma cell lines through MTT assay.

Abstract
Dermacoccus abyssi sp. nov. strains MT1.1 and MT1.2 are actinomycetes isolated from a Mariana Trench sediment at a depth of 10 898 m. The fermentation process using complex media led to the production of three new pigmented heteroaromatic (oxidized and reduced) phenazine compounds, dermacozines H-J (1-3). Extensive use was made of 1D and 2D NMR experiments and high-resolution MS to determine the structures of the compounds. The new dermacozines showed radical scavenging activity, and the highest activity was observed for dermacozine H (1), with an IC50 value of 18.8 μM.

Abstract
The aim of the present study was to test the hypothesis that oxidative stress and alteration of oxidative metabolism and apoptosis of neutrophils in dogs vary with the stage of leishmaniasis and to determine the contribution of uremia to such alterations. Dogs with leishmaniasis were classified into two stages: moderate (Leish II, n=20) or very severe (i.e. with concurrent uremia; Leish IV, n=20) according to the LeishVet Consensus. The two leishmaniasis groups were compared with uremic dogs without leishmaniasis (Uremic, n=10) and to healthy dogs (Control, n=30). To determine oxidative stress, total antioxidant/oxidant capacity, lipid peroxidation, total glutathione and the plasma antioxidants albumin, uric acid and bilirubin were quantified. Superoxide production was determined using the hydroethidine probe and viability and apoptosis were measured using annexin V-PE by capillary flow cytometry. Oxidative stress was present in both uremia and leishmaniasis with reduced total antioxidant capacity and was associated with increased induced production of superoxide and apoptosis. The greatest amount of oxidants was observed in animals with moderate disease only. Neutrophils from uremic dogs with and without leishmaniasis had decreased viability and an increased apoptosis rate in addition to increased lipid peroxidation. In conclusion, oxidative stress occurs in both stages of leishmaniasis with differences in intensity and levels of plasma markers; however, uremia does contribute to the decreased spontaneous viability of neutrophils in dogs in the final stage of the disease.
