Antifungal Constituent ofSapium japonicum

Antifungal and antibacterial activities of Pentanema divaricatum and its active constituent.

The antimicrobial activity of ethanol and chloroform extracts of Pentanema divaricatum Cass. was studied using the conventional disk diffusion method. The extracts' highest antimicrobial activity was observed against Aspergillus niger. Bioassay-guided fractionation of the crude extract by preparative thin layer chromatography (PTLC) showed one antimicrobial fraction which was especially effecti...

Antifungal activity of Thymus vulgaris L. essential oil and its constituent phytochemicals against Rhizopus oryzae: interaction with ergosterol.

Mucormycoses are emerging infections that have high rates of morbidity and mortality. They show high resistance to antifungal agents, and there is a limited therapeutic arsenal currently available, therefore, there is a great need to give priority to testing therapeutic agents for the treatment of mucormycosis. Along this line, the use of essential oils and phytoconstituents has been emphasized...

Antifungal and cytotoxicity activities of the fresh xylem sap of Hymenaea courbaril L. and its major constituent fisetin

BACKGROUND The great potential of plants as Hymenaea courbaril L (jatoba) has not yet been throughly explored scientifically and therefore it is very important to investigate their pharmacological and toxicological activities to establish their real efficacy and safety. This study investigated the cytotoxicity of xylem sap of Hymenaea courbaril L and its bioactivity against the fungi Cryptococc...

Enantioselective synthesis of four isomers of 3-hydroxy-4-methyltetradecanoic acid, the constituent of antifungal cyclodepsipeptides W493 A and B.

Four possible stereoisomers of 3-hydroxy-4-methyltetradecanoic acid were enantioselectively synthesized by using Sharpless epoxidation and a subsequent epoxide-ring opening reaction with trimethylaluminum as the key steps. The absolute configuration of the beta-oxyacid component of antifungal cyclodepsipeptides W493 A and B was consequently determined as 3S,4R.
