Chemical Constituents of a Marine-derived Fungus Fusarium oxysporum F0888 and their Antibacterial Activity.

Abstract

Five new compounds, including four hydroxyphenylacetic acid derivatives, stachylines H-K (1-4), a derivative of hydroxyphenylethanol (5), as well as seven known compounds were obtained from a marine-derived fungus Fusarium oxysporum F0888 isolated from sediments in the South China Sea. The structures and absolute configurations of new compounds were determined by spectroscopic (IR, NMR, and HR-ESI-MS) analyses, comparison of optical rotations, and the modified Mosher's MTPA ester method. Antimicrobial and anti-inflammatory activities of compounds 1-12 were tested. Unfortunately, all of isolated compounds were inactivity.
