Metabolite Identification
Common Name2-epi-botcinin A
Description2-epi-botcinin A is a secondary metabolite belonging to the class of botcinins, which are produced by the fungus Botrytis cinerea. This compound, along with 3-O-acetylbotcineric acid, was isolated from the aforementioned fungal species, highlighting its biosynthetic origin (PMID:17928694 ). In terms of biological activity, 2-epi-botcinin A has been evaluated for its antifungal properties, specifically against Magnaporthe grisea, the pathogen responsible for rice blast disease. The compound exhibited an antifungal activity that was eight times less potent than that of its structural analog, botcinin A, with a minimum inhibitory concentration (MIC) of 100 µM (PMID:17928694 ). Furthermore, structural elucidation studies have revealed that 2-epi-botcinin A can be chemically converted to related compounds, such as 3-O-deacetyl-2-epi-botcinin A, through spectroscopic methods (PMID:16643065 ). These findings underscore the significance of 2-epi-botcinin A in the context of fungal metabolites and their potential applications in agriculture and pharmacology.
