Abstract
Callingcard Vine (Entada polystachya (L.) DC. var. polystachya - Fabaceae) is a common plant in coastal thickets from western Mexico through Central America to Colombia and Brazil, especially in Amazon biome. It has been popularly used as a urinary burning reliever and diuretic. However, the plant chemical constituents are poorly understood and Entada spp. genotoxic potential have not been previously investigated. In the present study we determined the chemical composition of the aqueous E. polystachya crude seed extract (EPCSE) and evaluated the cytotoxic, genotoxic and mutagenic properties of EPCSE in Salmonella typhimurium and Chinese hamster fibroblast (V79) cells. Cytotoxic activity was also evaluated in tumor cell lines (HT29, MCF7 and U87) and non-malignant cells (MRC5). The chemical analysis by High Resolution Mass Spectrometry (HRMS) of EPCSE indicated the presence of saponin and chalcone. The results of the MTT and clonal survival assays suggest that EPCSE is cytotoxic to V79 cells. Survival analysis showed higher IC50 in non-tumor compared with tumor cell lines. EPCSE showed induction of DNA strand breaks as revealed by the alkaline comet assay and micronucleus test. Using the modified comet assay, it was possible to detect the induction of oxidative DNA base damage by EPCSE in V79 cells. Consistently, the extract induced increase lipid peroxidation (TBARS), superoxide dismutase (SOD) and catalase (CAT) activities in V79 cells. In addition, EPCSE induced mutations in S. typhimurium TA98 and TA100 strains, confirming a mutagenic potential. Taken together, our results suggest that EPCSE is cytotoxic and genotoxic to V79 cells and mutagenic to S. typhimurium. These properties can be related to the pro-oxidant ability of the extract and induction of DNA lesions. Additionally, EPCSE could inhibit the growth of tumor cells, especially human colorectal adenocarcinoma (HT29) cell line, and can constitute a possible source of antitumor natural agents.

Antiplasmodial activity of constituents and their metabolites after in vitro gastrointestinal biotransformation of a Nauclea pobeguinii extract. PHYTOCHEMISTRY 2022; 194:113029. [PMID: 34844038 DOI: 10.1016/j.phytochem.2021.113029] [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: 09/29/2021] [Revised: 11/19/2021] [Accepted: 11/20/2021] [Indexed: 06/13/2023]
Abstract
Nauclea pobeguinii is traditionally used for treatment of malaria. Previous studies on the plant extract and strictosamide, the putative active constituent, showed a profound in vivo activity of the extract but no in vitro activity of strictosamide. This might indicate that one or more compounds present in the extract, most likely alkaloids, act as prodrugs undergoing biotransformation after oral administration resulting in the active compounds. The phytochemical composition of a N. pobeguinii extract was characterized using UHPLC-UV-HRMS (Ultrahigh-Performance Liquid Chromatography-Ultraviolet-High Resolution Mass Spectrometry) data. An in vitro gastrointestinal model was used to simulate biotransformation of the extract allowing monitoring of the relative abundances of individual constituents over time on one hand, while antiplasmodial activity and cytotoxicity of the biotransformed extract could be evaluated on the other hand. A diversity of compounds was (tentatively) identified in the extract, mainly saponins and alkaloids, including 32 compounds that have not been reported before in N. pobeguinii. The automated data analysis workflow used for unbiased screening for metabolites showed that glycosylated compounds decreased in intensity over time. Alkaloids containing no sugar moieties, including angustine-type alkaloids, showed no gastrointestinal biotransformation. In vitro gastrointestinal biotransformation of strictosamide did not result in a major metabolite. Moreover, multivariate data analysis using Orthogonal Partial Least Square-Discriminant Analysis (OPLS-DA) showed no in vitro activity of strictosamide or its metabolites suggesting that other compounds or metabolites present in the extract are responsible for the antiplasmodial effect of the N. pobeguinii extract. The OPLS-DA proposes alkaloids with a β-carboline moiety as active principles, suggesting that antiplasmodial activity of N. pobeguinii derives from an additive or synergistic effect of multiple minor alkaloids and their metabolites present in the bark extract of N. pobeguinii.

Evaluation of antioxidant, anti-inflammatory and anticancer activities of diosgenin enriched Paris polyphylla rhizome extract of Indian Himalayan landraces. JOURNAL OF ETHNOPHARMACOLOGY 2021; 270:113842. [PMID: 33460752 DOI: 10.1016/j.jep.2021.113842] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Revised: 11/27/2020] [Accepted: 01/08/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional medicinal plants have gained attention as a potential therapeutic agent to combat cancer and inflammation. Diosgenin rich fresh extracts of Paris polyphylla rhizome from Indian Himalaya is traditionally used as wound healing, anti-bleeding, anti-inflammatory and anti-cancer agent by the folk healers. AIM OF THE STUDY Present study was aimed to prepare two types of extracts from Paris polyphylla rhizome of Indian Himalayan landraces - 1. ethanolic extract of Paris polyphylla rhizome (EEPPR) and 2. Diosgenin enriched Paris polyphylla rhizome extract (DPPE), quantification of diosgenin content, and to evaluate their in vitro anti-oxidant, in vivo anti-inflammatory and in vitro cytotoxicity and anti-cancer activities of the DPPE. MATERIALS AND METHODS Diosgenin content of EEPPR was quantified through GC-MS while diosgenin content of DPPE was quantified through HPTLC, and the diosgenin yield from EEPPR and DPPE were compared. In vitro antioxidant activities of DPPE were performed using DPPH, NOD, RP and SOD assay while in vivo anti-inflammatory activity of DPPE were evaluated in dextran induced hind paw edema in rats. In vitro cytotoxicity and anti-cancer activities of DPPE were evaluated in human breast cancer cell lines (MCF-7, MDA-MB-231), cervical cancer cell lines (HeLa) and Hep-2 cell lines. RESULTS EEPPR obtained through cold extraction method using 70% ethanol showed maximum diosgenin content of 17.90% quantified through GC-MS while similar compounds pennogenin (3.29%), 7β-Dehydrodiosgenin (1.90%), 7-Ketodiosgenin acetate (1.14%), and 7 β-hydroxydiosgenin (0.55%) were detected in low concentration, and thus confirmed diosgenin as major and lead phytochemical. However, DPPE obtained through both cold and repeated hot extraction with the same solvent (70% ethanol) showed diosgenin content of 60.29% which is significantly higher (p < 0.001) than the diosgenin content in EEPPR. DPPE demonstrated significant in vitro antioxidant activities by dose-dependently quenched (p < 0.001) SOD free radicals by 76.66%, followed by DPPH (71.43%), NOD (67.35%), and RP (63.74%) at a max concentration of 2 μg/μl of ascorbic acid and test drugs with remarkable IC50 values (p < 0.01). Further, DPPE also showed potent anti-inflammatory activities by dose-dependently suppressed dextran induced paw edema in rats (p < 0.01) from 2 h to 4 h. DPPE suppressed the proliferation of MCF-7, MDA-MB-231, Hep-2 and HeLa cell lines. Maximum activity was observed in MCF-7 cells. The DPPE also induced apoptosis in MCF-7 cell lines as measured by AO/PI and DAPI staining, as well as DNA laddering, cell cycle analysis and phosphatidylserine externalization assay. The growth-inhibitory effect of DPPE on MCF-7 breast cancer cells was further confirmed from the colony-formation assay. DPPE upregulated expression of Bax and downregulated Bcl-2 and survivin mRNA transcripts. CONCLUSION DPPE obtained through both cold and repeated hot extraction using ethanol showed significantly higher content of diosgenin than the diosgenin content detected in EEPPR. However, diosgenin yield of both the extracts (EEPPR & DPPE) clearly confirmed diosgenin as major and lead phytochemical of Paris polyphylla rhizome of Indian Himalayan landraces. Further, DPPE also demonstrated potent in vitro anti-oxidative and in vivo anti-inflammatory activities and showed in vitro cytotoxicity and significant anti-cancer (apoptosis) effects in MCF-7 breast cancer cells.

Abstract
The zebrafish (Danio rerio) is used as an embryonic and larval model to perform in vitro experiments and developmental toxicity studies. Zebrafish may be used to determine the toxicity of samples in early screening assays, often in a high-throughput manner. The zebrafish embryotoxicity model is at the leading edge of toxicology research due to the short time required for analyses, transparency of embryos, short life cycle, high fertility, and genetic data similarity. Zebrafish toxicity studies range from assessing the toxicity of bioactive compounds or crude extracts from plants to determining the optimal process. Most of the studied extracts were polar, such as ethanol, methanol, and aqueous solutions, which were used to detect the toxicity and bioactivity. This review examines the latest research using zebrafish as a study model and highlights its power as a tool for detecting toxicity of medicinal plants and its effectiveness at enhancing the understanding of new drug generation. The goal of this review was to develop a link to ethnopharmacological zebrafish studies that can be used by other researchers to conduct future research.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Majority of people living in Ghana and many other developing countries rely on traditional medicinal plants for their primary healthcare. These plants are used either alone or in combination to manage a wide range of ailments. However, most of these plants have not been investigated for their mutagenic effects. AIM OF THE STUDY This study, therefore aimed at evaluating the mutagenic activity of the most frequently used medicinal plants amongst Ghanaians living within the Accra metropolis, Ghana. MATERIALS AND METHODS Validated questionnaires were administered to 53 herbalists and herbal medicines dealers in the Makola, Madina and Nima communities. Plants that were identified as being frequently used were investigated for their mutagenicity using the Ames test. RESULTS A total of 110 medicinal plants belonging to 53 families were identified as most frequently used plants in the study sites. These are used to treat various ailments including gastric ulcer, fever, malaria, male impotence, diabetes, typhoid, high blood pressure and candidiasis. Thirteen samples (52%) showed moderate to high mutagenicity in the TA 100 bacterial strain before and after metabolism with rat liver enzyme. CONCLUSIONS The study showed that over half of the frequently used medicinal plants showed moderate to high mutagenicity before and after metabolism at the concentration of a 100 μg/mL. This may have implications for the safety of those who use them to manage diseases. These findings will suggest the need for an in-depth study of the mutagenic potentials of plants commonly used by indigenous people and more especially for those exhibiting high mutagenicity in this study.

Abstract
ETHNOPHARMACOALOGICAL RELEVANCE The genus Nauclea in Africa comprises seven species. Among them, N. latifolia, N. diderrichii and N. pobeguinii are widely used by the local population in traditional remedies. Preparation from various parts of plants (e.g. roots, bark, leaves) are indicated by traditional healers for a wide range of diseases including malaria, pain, digestive ailments or metabolic diseases. MATERIALS AND METHODS A literature search was conducted on African species of the genus Nauclea using scientific databases such as Google Scholar, Pubmed or SciFinder. Every document of ethnopharmacological, phytochemical or pharmacological relevance and written in English or French were analyzed. RESULTS AND DISCUSSION The Nauclea genus is used as ethnomedicine all along sub-Saharan Africa. Several local populations consider Nauclea species as a major source of remedies for malaria. In this regard, two improved traditional medicines are currently under development using extracts from N. latifolia and N. pobeguinii. Concerning the chemical composition of the Nauclea genus, indoloquinolizidines alkaloids could be considered as the major class of compounds as they are reported in every analyzed Nauclea species, with numerous structures identified. Based on traditional indications a considerable amount of pharmacological studies were conducted to ensure activity and attempt to link them to the presence of particular compounds in plant extracts. CONCLUSION Many experimental studies using plant extracts of the African species of the genus Nauclea validate traditional indications (e.g. malaria and pain). However, bioactive compounds are rarely identified and therefore, there is a clear need for further evaluations as well as for toxicity experiments. The sustainability of these plants, especially of N. diderrichii, a threatened species, should be kept in mind to adapt local uses and preparation modes of traditional remedies.

Analysis of antioxidant, cytotoxic and mutagenic potential of Agave sisalana Perrine extracts using Vero cells, human lymphocytes and mice polychromatic erythrocytes. Biomed Pharmacother 2018; 98:873-885. [PMID: 29571258 DOI: 10.1016/j.biopha.2018.01.022] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2017] [Revised: 12/31/2017] [Accepted: 01/03/2018] [Indexed: 10/18/2022] Open
Abstract
Brazilian Northeast is the world's largest producer of Agave sisalana Perrine for the supply of the sisal fiber. About 95% of plant biomass, which comprise the mucilage and sisal juice, is considered a waste residual is discarded in the soil. However, the sisal juice is rich in steroidal saponins, which exhibits different pharmacological properties. Despite this, natural products are not necessarily safe. Based on this, this study analyzed the antioxidant, cytotoxic and mutagenic potential of three extracts derived from acid hydrolysis (AHAS), dried precipitate (DPAS) and hexanic of A. sisalana (HAS). These analyses were performed by in vitro and in vivo methods, using Vero cells, human lymphocytes and mice. Results showed that AHAS 50 and 100 can be considered a useful antineoplastic candidate due to their antioxidant and cytotoxic activity, with no genotoxic/clastogenic potential in Vero cells and mice. Although the comet assay in human lymphocytes has showed that the AHAS 25, AHAS 50 and AHAS 100 can lead to DNA breaks, these extracts did not promote DNA damages in mice bone marrow. Considering the different mutagenic responses obtained with the different methods employed, this study suggest that the metabolizing pathways can produce by-products harmful to health. For this reason, it is mandatory to analyze the mutagenic potential by both in vitro and in vivo techniques, using cells derived from different species and origins.

JOURNAL OF COMPLEMENTARY MEDICINE RESEARCH 2017; 6:206-217. [PMID: 28512602 PMCID: PMC5429081 DOI: 10.5455/jice.20170414055506] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2016] [Accepted: 03/21/2017] [Indexed: 12/14/2022]
Abstract
BACKGROUND/AIM People suffering of diabetes increased significantly worldwide. Population, in Sub-Saharan Africa and mainly in Gabon, rely on medicinal plants to manage diabetes, as well in rural as in urban areas. This study aimed to survey a wide range of Gabonese plants for their antidiabetic activity. MATERIALS AND METHODS This study focused on the identification of medicinal plants used in the local treatment of diabetes mellitus. Ethnobotanical investigations were carried out in rural and urban areas of three provinces of Gabon using a semi-structured interview. RESULTS About 50 plant species belonging to 31 families and 50 genera were recorded, a majority of which have been documented previously to have medicinal properties. Most have documented antidiabetic properties with characterized therapeutic chemical compounds. Of the plant parts used for treatment, stem barks were employed most frequently (50%), followed by leaves (26%); the remaining 24% comprised roots, fibers, fruit, bulbs, flowers, rhizom, skin, and stem. Regarding the mode of preparation, decoction was the most widely used (58%), followed by maceration (18%) and infusion (14%). Almost all the plant products were administered orally (98%). CONCLUSIONS Taken in concert, this study highlights the possibility of exploiting traditional knowledge of specific medicinal plants for the inexpensive treatment and management of diabetes.

Effect of Hecogenin on DNA instability. Toxicol Rep 2016; 3:539-543. [PMID: 28959577 PMCID: PMC5615936 DOI: 10.1016/j.toxrep.2016.06.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2016] [Revised: 06/13/2016] [Accepted: 06/14/2016] [Indexed: 11/24/2022] Open
Abstract
Hecogenin is a sapogenin found in Agave species in high quantities and is responsible for the many therapeutic effects of these medicinal plants. In addition, this compound is also widely used in the pharmaceutical industry as a precursor for the synthesis of steroidal hormones and anti-inflammatory drugs. Despite Hecogenin being widely used, little is known about its toxicological properties. Therefore, the present study aimed to investigate the cytotoxic, genotoxic and mutagenic effects of Hecogenin on HepG2 cells. Cytotoxicity was analyzed using the MTT test. Then, genotoxic and mutagenic potentials were assessed by comet assay and cytokinesis-block micronucleus assay, respectively. Cytotoxic effect was observed only when cells were exposed to concentrations of Hecogenin equal or higher than 100 μM. Although a lower concentration of Hecogenin caused DNA damage, a reduction on nuclear mutagenic markers in HepG2 cells was observed. The results indicated that Hecogenin treatment generated DNA damage, but in fact it would be repaired, avoiding dissemination of the damage throughout the cell division. Further studies need to be performed to confirm the observed protective effect of Hecogenin against genomic instability.

Cell wall integrity, genotoxic injury and PCD dynamics in alfalfa saponin-treated white poplar cells highlight a complex link between molecule structure and activity. PHYTOCHEMISTRY 2015; 111:114-123. [PMID: 25660272 DOI: 10.1016/j.phytochem.2015.01.008] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2014] [Revised: 01/10/2015] [Accepted: 01/15/2015] [Indexed: 06/04/2023]
Abstract
In the present work, eleven saponins and three sapogenins purified from Medicago sativa were tested for their cytotoxicity against highly proliferating white poplar (Populus alba L.) cell suspension cultures. After preliminary screening, four saponins with different structural features in terms of aglycone moieties and sugar chains (saponin 3, a bidesmoside of hederagenin; saponins 4 and 5, monodesmoside and bidesmoside of medicagenic acid respectively, and saponin 10, a bidesmoside of zanhic acid) and different cytotoxicity were selected and used for further investigation on their structure-activity relationship. Transmission Electron Microscopy (TEM) analyses provided for the first time evidence of the effects exerted by saponins on plant cell wall integrity. Exposure to saponin 3 and saponin 10 resulted into disorganization of the outer wall layer and the effect was even more pronounced in white poplar cells treated with the two medicagenic acid derivatives, saponins 4 and 5. Oxidative burst and nitric oxide accumulation were common hallmarks of the response of white poplar cells to saponins. When DNA damage accumulation and DNA repair profiles were evaluated by Single Cell Gel Electrophoresis, induction of single and double strand breaks followed by effective repair was observed within 24h. The reported data are discussed in view of the current issues dealing with saponin structure-activity relationship.

Abstract
The use of vegetal extracts requires toxicological and genotoxic evaluations to establish and verify safety before being added to human cosmetic, pharmaceutical medicine, or alimentary products. Persea americana seeds have been used in traditional medicine as treatment for several diseases. In this work, the ethanolic seed extract of Persea americana was evaluated with respect to its genotoxic potential through micronucleus assay in rodents. The frequency of micronuclei in groups of animals treated with avocado seed extract showed no differences compared to the negative control (vehicle); therefore, it is considered that the avocado seed extract showed no genotoxic activity in the micronucleus test.
