Anti-Microbial Diketopiperazines from the Sea Urchin-Derived Penicillium sp. M408
Marine fungi are valuable sources of biologically active metabolites. During the course of our screening program, the ethyl acetate extract of a marine-derived fungus strain (Penicillium sp. M408) exhibited anti-microbial activities against both gram positive bacteria and a yeast strain. This paper reported the isolation, structure elucidation, and anti-microbial activities of six diketopiperazines, cyclo(L-Pro-L-Val) (1), cyclo(L-Pro-L-Leu) (2), cyclo(L-Pro-L-Phe) (3), cyclo(L-Pro-L-Trp) (4), tryprostatin B (5), and 12,13-dihydroxy-fumitremorgin C (6) from the fungus strain M408 associated with Echinometra lucunter (Linnaeus, 1758). Only compounds 5 and 6 exhibited anti-microbial activities against tested microbial pathogens.
