Ten compounds were isolated from the culture of Aspergillus versicolor M852, an endophytic fungus isolated from the marine mollusca at Hon Cau 2, Binh Thuan, Vietnam. These compounds include (2R)-2,3-dihydro-7-hydroxy-6,8-dimethyl-2-[(E)-prop-1-enyl]-chroman-4-one (1), fumigaclavine I (2), fumigaclavine C (3), cyclo-(Pro-Phe) (4), cyclo-(Pro-Tyr) (5), cyclo-(Pro-Ala) (6), cyclo-(Pro-Val) (7), norharman (8), phloretic acid (9), and 3-phenylpropanoic acid (10). Their structures were identified through MS and NMR data analyses. These compounds were then assessed for their antimicrobial activity against a range of clinically significant microorganisms. Most of them exhibited inhibitory activity against one to three tested Gram-positive strains, with MIC values ranging from 64 to 256 µg/mL.
