Abstract

One new pyrone derivative, named penicillone (1), together with paxilline, pyrenocines A (2) and B (3) were isolated from the endophytic fungus Penicillium paxilli PSU-A71. The structures were elucidated by spectroscopic methods. Pyrenocine B (3) mildly inhibited the growth of Microsporum gypseum SH-MU-4 with a MIC value of 32 μg/ml.
