Antimicrobial constituents from a marine brown alga-associated fungus Albifimbria terrestris
Tsai-Yen Shih
National Taiwan University, Taiwan
The discovery of new natural products from marine-derived fungi has increased drastically over the last few decades and some
of them revealed great potentials for drug developments. In our preliminary screening, the bioactivities of 300 fungal strains,
isolated from marine alga collected from northeast coast of Taiwan, were tested intensively. Of these, the ethyl acetate extract of
the fermented broth of Albifimbria terrestris, isolated from marine brown alga Sarrassum fulvellum was found to exhibit significant
antifungal activity against Candida albicans. Therefore, bioassay-guided separation of the active principles from this extract was
carried out and which has resulted in the isolation and identification of compounds following compounds: Myrochromanic acid,
roridin A, roridin D, roridin J, epiisororidin E, verrucarin A, verrucarin B, verrucarin J, verrucarin H and trichoverrin A. Their
structures were elucidated by spectroscopic analysis and myrochromanic acid was previously unreported.
