Abstract
Background
Almost from the very beginning of human existence, man has been interacting with plants. Throughout human history, plants have provided humans with basic needs such as sustenance, firewood, livestock feed, and wood. The world has approximately 3 million vascular plants. The treatment of primary health problems is provided primarily by traditional medicines by around 80% of the world's population. Compared to other vascular plants, pteridophytes remain underexplored in ethnobotanical aspects, despite being regarded as a valuable component of healthcare for centuries. As an alternative medicine, pteridophytes are being investigated for their pharmacological activity. Almost 2000 years ago, humans were exploring and using plant species from this lineage because of its beneficial properties since pteridophytes were the first vascular plants.

Cytotoxic Activity, Cell Cycle Inhibition, and Apoptosis-Inducing Potential of Athyrium hohenackerianum (Lady Fern) with Its Phytochemical Profiling. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:2055773. [PMID: 35692581 PMCID: PMC9184205 DOI: 10.1155/2022/2055773] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 04/10/2022] [Accepted: 05/12/2022] [Indexed: 01/20/2023]
Abstract
In the present study, we investigated the cytotoxic effects of Athyrium hohenackerianum ethanolic extract (AHEE) on the proliferation of breast, lung, and colon cancer cells. The AHEE was tested for its effect on the progression of the cell cycle, followed by induction of apoptosis determination by flow cytometry. Real-time qRT-PCR was also utilized to observe the initiation of apoptosis. In addition, GC-MS was performed in order to identify the active phytochemicals present in the AHEE. A cytotoxic activity with an IC50 value of 123.90 μg/mL against HCT-116 colon cancer cells was exhibited by AHEE. Following propidium iodide staining, annexin-V/PI, and clonogenic assays, AHEE treatment results in cell arrest in the S phase, causing an increase in the early and late phases of apoptosis and displaying antiproliferative potential, respectively. The morphological alterations were further monitored using acridine orange/ethidium bromide (AO/EB) staining. When compared with the control cells, features of apoptotic cell death, including nuclear fragmentation, in the AHEE-treated cells were noticed. The apoptosis was also confirmed by detecting the increased expression of p53 and caspase-3 along with the downregulation of Bcl-2. GC-MS analysis revealed that trans-linalool oxide, loliolide, phytol, 4,8,12,16-tetramethylheptadecan-4-olide, and gamma-sitosterol were the major phytochemical constituents. Based on these findings, it can be suggested that AHEE causes cellular death via apoptosis, which should be further explored for the identification of active compounds responsible for these observed effects. Therefore, AHEE can be used in the pharmaceutical development of anticancer agents for cancer therapeutics.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 283:114746. [PMID: 34656668 DOI: 10.1016/j.jep.2021.114746] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 09/22/2021] [Accepted: 10/11/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE For thousands of years, different cultural groups have used and transformed natural resources for medicinal purposes focused on psychological or neurological conditions. Some of these are recognized as central nervous system (CNS) disorders and diseases, whereas other ethnopsychiatric interpretations are explained in culture-specific terms. In traditional Mayan medicine, several herbs have been part of treatments and rituals focused on cultural and ethnomedical concepts. AIM OF REVIEW This study aims to provide a comprehensive overview of the medicinal plants used in Mesoamerica by traditional healers and Mayan groups to CNS disorders and associate the traditional use with demonstrated pharmacological evidence to establish a solid foundation for directing future research. METHODS A systematic search for primary sources of plant use reports for traditional CNS-related remedies of Mesoamerica were obtained from library catalogs, thesis and scientific databases (PubMed, Scopus, Google Scholar; and Science Direct), and entered in a database with data analyzed in terms of the usage frequency, use by ethnic groups, plant endemism, and pharmacological investigation. RESULTS A total of 155 plants used for ethnopsychiatric conditions in Mesoamerica by Mayan groups were found, encompassing 127 native species. Of these, only 49 native species have reported in vitro or in vivo pharmacological analyses. The most commonly reported ethnopsychiatric conditions are related to anxiety, depression, memory loss, epilepsy, and insomnia. The extent of the scientific evidence available to understand the pharmacological application for their use against CNS disorders varied between different plant species, with the most prominent evidence shown by Annona cherimola, Justicia pectoralis, J. spicigera, Mimosa pudica, Persea americana, Petiveria alliacea, Piper amalago, Psidium guajava, Tagetes erecta and T. lucida. CONCLUSION Available pharmacological data suggest that different plant species used in traditional Mayan medicine may target the CNS, mainly related to GABA, serotonin, acetylcholine, or neuroprotective pathways. However, more research is required, given the limited data regarding mechanism of action at the preclinical in vivo level, identification of active compounds, scarce number of clinical studies, and the dearth of peer-reviewed studies.

Abstract
Objectives The aim of this study was to evaluate the influence of metal ions present in soil as well as in leaf samples of Calendula officinalis and Phlebodium decumanum for the treatment of psoriasis. Materials and Methods To meet the objective, soil and leaf samples were estimated for metal ions by atomic absorption spectrophotometer to determine the influence in antipsoriatic activity. Thereafter imiquimod-induced dermatitis lesions were created in grouped mice. Two plant extracts (aqueous) separately as well as in combinations and standard Retino-A (0.05%) were used. Psoriasis severity index (PSI) was evaluated according to the phenotypic (redness, erythema, and scales) and histological features (epidermal thickness). Further content of phytochemicals in terms of extract was correlated with the effect of psoriasis activity. Results We observed redness, erythema, and scales and the histological features and found a progressive reduction (P<0.05) in the severity of psoriatic lesions (redness, erythema, and scales) from days 7 to 21 and decreased epidermal thickness in animals treated with combined extracts at a dose of 200 mg/kg b.w. Furthermore, plant samples procured from the Nandi Hills, Bangalore, showed better uptake of metals with respect to Fe (2.05 mg/kg), Cu (0.78 mg/kg), and Zn (1.12 mg/kg), which showed a positive impact on procurement of maximum amount of extracts that further correlated with the activity, indicating a significant reduction in psoriatic lesions. Conclusion The results revealed that the significant dose-dependent antipsoriasis activity of combined aqueous extracts of C. officinalis and P. decumanum as well as metal ions had an impact on the procurement of extracts and said activity.

Abstract
The aim of this review was to explore the pharmacological activity of early tracheophytes (pteridophytes) as an alternative medicine for treating human ailments. As the first vascular plants, pteridophytes (aka, ferns and fern allies) are an ancient lineage, and human beings have been exploring and using taxa from this lineage for over 2000 years because of their beneficial properties. We have documented the medicinal uses of pteridophytes belonging to thirty different families. The lycophyte Selaginella sp. was shown in earlier studies to have multiple pharmacological activity, such as antioxidant, anti-inflammatory, anti-cancer, antidiabetic, antiviral, antimicrobial, and anti-Alzheimer properties. Among all the pteridophytes examined, taxa from the Pteridaceae, Polypodiaceae, and Adiantaceae exhibited significant medicinal activity. Based on our review, many pteridophytes have properties that could be used in alternative medicine for treatment of various human illnesses. Biotechnological tools can be used to preserve and even improve their bioactive molecules for the preparation of medicines against illness. Even though several studies have reported medicinal uses of ferns, the possible bioactive compounds of several pteridophytes have not been identified. Furthermore, their optimal dosage level and treatment strategies still need to be determined. Finally, the future direction of pteridophyte research is discussed.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Porvenir is a semi-isolated Indian community in the Bajo Paraguá Indian Reservation in Bolivian Amazon, one of the two communities of people from the Guarasug'we indigenous nation now close to extinction. The aim of our study was the collection of data on the traditional medicine utilized in the community, and to identify new subjects for further investigation by comparison of the folk-medicinal use with the available scientific literature data. MATERIALS AND METHODS Field work was conducted for 5 months, which included participant observation, semi-structured interviews with 16 individuals, and the collection of voucher specimens for botanical identification. The knowledge of the inhabitants relating to medicinal plants was analysed by means of the modified method of Gentry and Phillips (1993a,b), which assesses the frequency and the variety of use of plants. Scientific data were gathered on selected species, and the correlations of the traditional uses of the herbs with scientific evidence were assessed. RESULTS The lifestyle and beliefs in Porvenir, botanical data on the plants used, the frequency and variety of medicinal use, diseases that occur and their possible treatment, and methods of plant application are discussed in detail. 145 plant species were registered with 451 recorded uses. The majority of the plants were utilized to treat gastrointestinal complaints (60 species), followed by diseases of the central nervous system, pain and fever (37 species), diseases of the genitourinary tract (35 species), dermatological disorders (34 species) and diseases of the respiratory system (32 species). One fifth of the species are also applied in traditional medicine in other areas of Bolivia or in other countries. The majority of the 145 species used in the community have not been extensively investigated from phytochemical and pharmacological aspects. There are no data in the scientific literature on one fifth of the species. CONCLUSIONS The medicine applied in Porvenir and the contemporary knowledge of the people interviewed concerning plants reflect the local traditions and their changes very well, clearly demonstrating the influence exerted by conventional medicine, and how the ancestral knowledge is progressively being forgotten. The present ethnopharmacological survey indicates that 24 species that are frequently and consistently used in the community of Porvenir are perspective for further research, as their chemistry and pharmacology have not been published to date.

Abstract
Strenuous exercise induces muscle damage due to a highly increased generation of free radicals and inflammatory response and therefore, in this type of exercise, it is important to reduce both oxidative stress and inflammation, at least their negative aspects. The purpose of this study was investigate, for the first time, whether a purified, standard water-soluble fraction obtained from Phlebodium decamanum could reduce the over-expression of inflammation and oxidative stress induced by strenuous exercise. The physical test consisted of a constant run that combined several degrees of high effort (mountain run and ultra-endurance), in permanent climbing. Biochemical parameters, oxidative stress and inflammatory mediators were assessed. The results showed that oral supplementation of P. decumanum during high-intensity exercise effectively reduces the degree of oxidative stress (decreased 8-hydroxy-2'-deoxyguanosine and isoprostanes generation, increased antioxidant enzyme activities in erythrocyte and total antioxidant status in plasma). The data obtained also indicate that this supplementation is efficient in reducing the inflammatory response through the decrease of TNF-α and increase of sTNF-RII, but kept the levels of IL-6 and IL-1ra. In conclusion, oral supplementation of P. decamanum extract during high-intensity exercise effectively reduces the degree of oxidative stress and has anti-inflammatory protective effects, preventing the over-expression of TNF-α but keeping the levels and effects of IL-6. These findings provide a basis for similar Phlebodium supplementation for both professional and amateur athletes performing strenuous exercise in order to reduce the undesirable effects of the oxidative stress and inflammation signalling elicited during high-intensity exercise.

Abstract
Tumor necrosis factor-alpha (TNF-alpha) was first isolated two decades ago as a macrophageproduced protein that can effectively kill tumor cells. TNF-alpha is also an essential component of the immune system and is required for hematopoiesis, for protection from bacterial infection and for immune cell-mediated cytotoxicity. Extensive research, however, has revealed that TNF-alpha is one of the major players in tumor initiation, proliferation, invasion, angiogenesis and metastasis. The proinflammatory activities link TNF-alpha with a wide variety of autoimmune diseases, including psoriasis, inflammatory bowel disease, rheumatoid arthritis, systemic sclerosis, systemic lupus erythematosus, multiple sclerosis, diabetes and ankylosing spondylitis. Systemic inhibitors of TNF such as etanercept (Enbrel) (a soluble TNF receptor) and infliximab (Remicade) and adalimumab (Humira) (anti-TNF antibodies) have been approved for the treatment inflammatory bowel disease, psoriasis and rheumatoid arthritis. These drugs, however, exhibit severe side effects and are expensive. Hence orally active blockers of TNF-alpha that are safe, efficacious and inexpensive are urgently needed. Numerous products from fruits, vegetable and traditional medicinal plants have been described which can suppress TNF expression and TNF signaling but their clinical potential is yet uncertain.

Abstract
Fructus Ligustrum lucidi (FLL) is a widely used herbal medicine for the treatment of a variety of pathologies. We have investigated the anti-inflammatory mechanism of FLL in mouse peritoneal macrophages. FLL exerted an anti-inflammatory action through inhibition of lipopolysaccharide (LPS)-induced tumour necrosis factor (TNF)-alpha production in mouse peritoneal macrophages. The maximal inhibition rate of TNF-alpha production by FLL (0.5 mg mL(-1)) was 60.88 +/- 0.30%. In the inflammatory process, nitric oxide (NO) and prostaglandin E(2) (PGE(2)) increased in peritoneal macrophages. FLL decreased the protein level of NO and PGE(2) in LPS-stimulated mouse peritoneal macrophages. In addition, FLL inhibited nuclear factor-kappaB activation and IkappaB-alpha degradation by the decrease in IkappaB-alpha phosphorylation. Our study suggested that FLL reduced inflammation via an important molecular mechanism, which might explain its beneficial effect in the regulation of inflammatory reactions.

Abstract
The medical ethnobotanical knowledge propagated over generations in the coastal regions of the Eastern Mediterranean, including Lebanon, is one that has built on several ancient cultures and civilizations of these regions. Recent interest in medical ethnobotany and the use of medicinal herbs in treating or preventing ailments has rejuvenated interest in folk medicine practices, especially those transcendent across generations. According to Eastern Mediterranean folk medicine practices, herbal remedies that treat many inflammation-related ailments were typically based on plant bioactive water extracts or decoctions. Studies have shown that active anti-inflammatory ingredients in water extracts include many natural chemicals such as phenols, alkaloids, glycosides, and carbohydrates. The intent of this manuscript is twofold: first, to review the literature that describes anti-inflammatory bioactivities in plant extracts of different plant genera; and second, to evaluate indigenous folk remedies used by folk doctors to treat inflammatory ailments in this region of the world. For this aim, the reported literature of five plant genera assumed to possess anti-inflammatory bioactivities and typically prescribed by folk doctors to treat inflammation-related ailments is reviewed.

Abstract
Glechoma hederacea (GH) is an herb widely used herb medicine for the treatment of a variety of pathologies. In this study, the effect of GH on interferon-gamma (IFN-gamma) and lipopolysaccharide (LPS)-induced production of nitric oxide (NO), interleukin (IL)-12p70, IL-12p40, tumor necrosis factor-alpha (TNF-alpha), and IL-6 were examined using mouse peritoneal macrophages. GH inhibits IFN-gamma/LPS-induced NO in a dose-dependent manner. The decrease in NO synthesis was reflected as a decreased amount of inducible NO synthase protein. We also found that GH inhibits pro-inflammatory cytokine, IL-12p70, and TNF-alpha production. However, GH increased IFN-gamma/LPS-induced IL-12p40 production. GH doesn't affect the IL-6 production. These findings mean that GH can be used in controlling macrophages mediated inflammation related disease.

Abstract
AIM To study the effects of propyl gallate on the interaction of tumor necrosis factor-alpha (TNF-alpha) with its soluble receptor, sTNFR-I. METHODS Interactions between TNF-alpha and sTNFR-I were analyzed using an IAsys biosensor. sTNFR-I was immobilized on the carboxymethyl dextran (CMD) surface of the IAsys biosensor cuvettes, and TNF-alpha preincubated with different concentrations of propyl gallate was added to the cuvettes. The resonant angle shift caused by the binding between TNF-alpha and sTNFR-I was then recorded. RESULTS sTNFR-I was immobilized on the CMD surface at a density of 2.76 ng/mm(2). TNF-alpha then bound the immobilized sTNFR-I specifically, and propyl gallate was able to enhance the binding between TNF-alpha and sTNFR-I in a dose-dependent manner. CONCLUSION The binding between TNF-alpha and sTNFR-I is one of the targets that propyl gallate can act on in vivo. The IAsys biosensor offers a new clue as to the study on the mechanisms of action of propyl gallate.
