This study was carried out to evaluate the antifungal efficacy of Dichrostachys cinerea extracts against some isolates of dermatophytic fungi. The powdered plant materials were extracted via soxhlet extraction technique using methanol, dichloromethane and petroleum ether as extraction solvents. The extracts were subjected to phytochemical screening for qualitative detection of plant secondary metabolites. The extracts were further tested for antifungal activity against human isolates of Microsporum canis, Trichophyton terrestre, Trichophyton mentagrophytes and Trichophyton verrucosum. The results of phytochemical screening showed the presence of some secondary metabolites including; alkaloids, tannins, saponins, glycosides and steroid. Antifungal activity testing indicated that all the extracts were active against the isolates tested with the exception of T. verrucosum. Pet ether extracts showed the least activity as reflected in the zone of inhibition (24 mm at 50 mg/ml), against the isolates compared to methanol (30 mm at 25 mg/ml) and dichloromethane (30 mm at 50 mg/ml) extracts. The findings of this study, indicated that the plant is a potential for the drug candidate for the treatment of dermatophytic diseases and support the claim for their traditional use against skin diseases

Natural Products (NP), specifically from medicinal plants or herbs, have been extensively utilized to analyze the fundamental mechanisms of ultimate natural sciences as well as therapeutics. Isolation of secondary metabolites from these sources and their respective biological properties, along with their lower toxicities and cost-effectiveness, make them a significant research focus for drug discovery. In recent times, there has been a considerable focus on isolating new chemical entities from natural flora to meet the immense demand for kinase modulators, and also to overcome major unmet medical challenges in relation to signal transduction pathways. The signal transduction systems are amongst the foremost pathways involved in the maintenance of life and protein kinases play an imperative part in these signaling pathways. It is important to find a kinase inhibitor, as it can be used not only to study cell biology but can also be used as a drug candidate for cancer and metabolic disorders. A number of plant extracts and their isolated secondary metabolites such as flavonoids, phenolics, terpenoids, and alkaloids have exhibited activities against various kinases. In the current review, we have presented a brief overview of some important classes of plant secondary metabolites as kinase modulators. Moreover, a number of phytocompounds with kinase inhibition potential, isolated from different plant species, are also discussed.

Acalypha wilkesiana (AW), a popular medicinal plant has been used in traditional medicine to treat a variety of skin disorders including pityriasis versicolor and seborrheic dermatitis. As a prelude to clinical trials in humans, an experimental study was carried out to determine the spectrum of antifungal activity of 2 variants of the Acalypha wilkesiana plant. Materials and Methods: The ethanol extract and herbal cream formulation of the dried leaves of 2 cultivars (Macrophylla & Hoffmani) of Acalypha wilkesiana were investigated for in-vitro antifungal activity by disc diffusion and micro-broth dilution techniques. Organisms tested were typed cultures of Malassezia furfur, Candida albicans and Trichophyton rubrum; and clinical strains of Microsporum canis and Epidermophyton floccosum. Results: Both cultivars (Macrophylla and Hoffmanii) of the plant showed good activity against all the fungi tested except Microsporum canis (8.0±0.00; 7.00±0.00 mm). The greatest activity was observed against Trichophyton rubrum (22.0±0.00; 24.00±0.00 mm) while Candida albicans showed the least activity (15.0±0.00; 18.00±0.57 mm). The Minimum Inhibitory Concentration (MIC) of the crude extract ranged between 0.25 and 8 mg/ml for all organisms, while that of the herbal cream was 0.31-8mg/ml. The lowest MIC was seen with Candida albicans for both varieties of the plant. The Acalypha wilkesiana Hoffmanii demonstrated a greater activity against Candida albicans and Malassezia furufur than the A. wilkesiana (Macrophylla). Conclusion: This study reveals Acalypha wilkesiana leaf extract has potential for development as a cream that can be used to treat superficial fungal skin infections.

Isoflavonoids — an overview of their biological activities and potential health benefitsThere are many biological activities attributed to isoflavonoids. The majority of them could be beneficial and some of them may be detrimental, depending on specific circumstances. Isoflavonoids play an important role in human nutrition as health promoting natural chemicals. They belong to plant secondary metabolites that mediate diverse biological functions through numerous pathways. They are structurally similar to estrogens, exerting both estrogenic and antiestrogenic properties in various tissues. The results of epidemiologic studies exploring the role of isoflavonoids in human health have been inconclusive. Some studies support the notion of a protective effect of their consumption in immunomodulation, cognition, risk reduction of certain cancers, cardiovascular and skin diseases, osteoporosis and obesity, as well as relief of menopausal symptoms. Other studies failed to demonstrate any effects.

L’objectif de ce travail est d’évaluer le pouvoir fongicide des feuilles de Mallotus oppositifolius sur Phytophthora sp. et Fusarium sp. deux champignons phytopathogènes dans le cadre de la recherche de substances naturelles d’origine végétale comme alternative aux pesticides chimiques en agriculture. Une enquête ethnobotanique réalisée auprès de quarante tradipraticiens de santé du District de Yamoussoukro sur les Euphorbiaceae médicinales a permis d’identifier treize espèces. L’étude a montré que les maladies de la peau (36%) étaient majoritairement traitées par ces Euphorbiaceae dont Mallotus oppositifolius. Au vue de ces données et celles de la littérature, Mallotus oppositifolius a été retenu pour l’évaluation du potentiel antifongique contre Fusarium sp. et Phytophthora sp. L'activité antifongique a été évaluée par la méthode de double dilution sur milieu PDA avec des extraits éthanoliques et aqueux dérivés des feuilles de cette plante. Les résultats ont montré que les extraits aqueux et éthanoliques 70% de Mallotus oppositifolius possèdent des propriétés antifongiques à la fois sur Fusarium sp. et Phytophthora sp. Les activités antifongiques ont été plus importantes avec les extraits éthanoliques qu’avec les extraits aqueux. Avec une concentration minimal inhibitrice CMI = 25±0,0 mg/mL, une CI50 = 6,5±0,05 mg/mL et une concentration minimal fongicide CMF = 200±0,0 mg/mL Fusarium sp. semble être le plus sensible. Phytophthora sp. est moins sensible avec une CMI = 50±0,0 mg/mL, une CI50 = 12±0,05 mg/mL et une CMF = 200±0,0 mg/mL. Le screening phytochimique a mis en évidence la présence de sept groupes de composés parmi lesquels les alcaloïdes, les polyterpènes et stérols, les tanins galliques et les catéchines sont les plus abondants dans les extraits éthanoliques. En plus de ces composés, les flavonoïdes, les polyphénols ainsi que les saponines sont aussi bien présents dans les extraits aqueux que dans les extraits alcooliques de Mallotus oppositifolius. Ces composés pourraient justifier l’activité des extraits éthanoliques de Mallotus oppositifolius. Ces résultats peuvent servir pour les recherches agronomiques dans le cadre de la lutte contre les deux champignons phytopathogènes étudiés. Botanical study, phytochemical screening and in vitro evaluation of the antifungal activity of Mallotus oppositifolius (Geisel.) Müll. Arg. (Euphorbiaceae) leaf extracts on Fusarium sp. and Phytophthora sp., two phytopathogenic fungi. ABSTRACT The purpose of this work is to evaluate the fungicidal power of the leaves of Mallotus oppositifolius on Phytophthora sp. and Fusarium sp. two phytopathogenic fungi in the research of natural substances of plant origin as an alternative to chemical pesticides in agriculture. An ethnobotanical survey of forty traditional healers in the Yamoussoukro District on medicinal Euphorbiaceae identified thirteen species.The study showed that skin diseases (36%) were mainly treated by these Euphorbiaceae including Mallotus oppositifolius. In view of these data and those in the literature, Mallotus oppositifolius was selected for the evaluation of the antifungal potential against Fusarium sp. and Phytophthora sp. The antifungal activity was evaluated by the double dilution method on PDA medium with ethanolic and aqueous extracts derived from the leaves of this plant. The results showed that aqueous and ethanolic extracts 70% of Mallotus oppositifolius have antifungal properties on both Fusarium sp. and Phytophthora sp. Antifungal activities were more important with ethanolic extracts than with aqueous extracts. With a minimum inhibitory concentration MIC = 25±0.0 mg/mL, a minimal concentration for 50 % of inhibition IC50 = 6.5±0.05 mg/mL and a minimum fungicide concentration MFC = 200±0.0 mg/mL Fusarium sp. appears to be the most sensitive. Phytophthora sp. is less sensitive with an MIC = 50±0.0 mg/mL, an IC50 = 12±0.05 mg/mL and a MFC = 200±0.0 mg/mL. Phytochemical screening revealed the presence of seven groups of compounds among which alkaloids, polyterpenes and sterols, gallic tannins and catechins are the most abundant in ethanol extracts. In addition to these compounds, flavonoids, polyphenols and saponins are present in both aqueous and alcoholic extracts of Mallotus oppositifolius. These compounds could justify the activity of the ethanolic extracts of Mallotus oppositifolius. These results can be used for agronomic research to control the two phytopathogenic fungi studied.

Induced Defense Responses

ABSTRACT Many plant species accumulate sterols and triterpenes as antimicrobial glycosides. These secondary metabolites (saponins) provide built-in chemical protection against pest and pathogen attack and can also influence induced defense responses. In addition, they have a variety of important pharmacological properties, including anticancer activity. The biological mechanisms underpinning the varied and diverse effects of saponins on microbes, plants, and animals are only poorly understood despite the ecological and pharmaceutical importance of this major class of plant secondary metabolites. Here we have exploited budding yeast (Saccharomyces cerevisiae) to investigate the effects of saponins on eukaryotic cells. The tomato steroidal glycoalkaloidα -tomatine has antifungal activity towards yeast, and this activity is associated with membrane permeabilization. Removal of a single sugar from the tetrasaccharide chain of α-tomatine results in a substantial reduction in antimicrobial activity. Surprisingly, the complete loss of sugars leads to enhanced antifungal activity. Experiments with α-tomatine and its aglycone tomatidine indicate that the mode of action of tomatidine towards yeast is distinct from that of α-tomatine and does not involve membrane permeabilization. Investigation of the effects of tomatidine on yeast by gene expression and sterol analysis indicate that tomatidine inhibits ergosterol biosynthesis. Tomatidine-treated cells accumulate zymosterol rather than ergosterol, which is consistent with inhibition of the sterol C24 methyltransferase Erg6p. However, erg6 and erg3 mutants (but not erg2 mutants) have enhanced resistance to tomatidine, suggesting a complex interaction of erg mutations, sterol content, and tomatidine resistance.
