Abstract:

In this study, we aimed to investigate the secondary metabolites from the coral-derived fungus Scopulariopsis sp. SCSIO 41229, collected from the Beibu Gulf. The fungal extract was isolated using silica gel column chromatography, reverse-phase silica gel column chromatography, thin-layer chromatography (TLC), and high-performance liquid chromatography (HPLC). The structures of the isolated compounds were elucidated through nuclear magnetic resonance (NMR), mass spectrometry (MS), and literature comparison. Nine known compounds were identified, including neocyclocitrinols A-D (1-4), penicillenol A2 (5), cyclo-(D-Phe-L-Ile) (6), cyclo-(L-tryptophyl-L-phenylalanyl) (7), (+)-penicilactam A (8), and (8E, 10E)-7-oxo-8, 10-heptadecadienoic acid (9). Notably, these compounds were reported from Scopulariopsis sp. for the first time. Bioassays indicated that compounds 2 and 4 exhibited weak antioxidant activity, while compounds 2, 4, and 8 showed weak acetylcholinesterase inhibitory activity.

Key words: coral-derived fungus, secondary metabolites, Scopulariopsis sp., C25 steroids
