The soil-derived fungus Talaromyces thailandensis PSU-SPSF059 produced a new vermistatin derivative called talarostatin, along with seven known compounds. The structures of these compounds were identified through extensive spectroscopic analysis. The absolute configuration of talarostatin was determined by comparing experimental and calculated electronic circular dichroism data. The antimicrobial and cytotoxic activities of the isolated secondary metabolites were also evaluated.
