epicoccins a-d, epipolythiodioxopiperazines from a cordyceps-colonizing isolate of epicoccum nigrum.	epicoccins a-d (1-4), four unique epipolythiodioxopiperazines possessing unusual sulfur bridges, have been isolated from cultures of a cordyceps-colonizing isolate of epicoccum nigrum. the structures of these compounds were determined mainly by analysis of their nmr spectroscopic data. the relative and absolute configuration of epicoccin a (1) was established by single-crystal x-ray diffraction analysis. epicoccin a (1) showed modest antimicrobial activity.	2007	17711348
diketopiperazines from the cordyceps-colonizing fungus epicoccum nigrum.	new diketopiperazines, epicoccins e-h (1-4) and diphenylalazines a (5) and b (6), have been isolated from the solid-substrate fermentation culture of the cordyceps-colonizing fungus epicoccum nigrum. the structures of 1-6 were determined primarily by nmr experiments, and the structure of 1 was confirmed by x-ray crystallography. the absolute configurations of 3 and 5 were assigned using the modified mosher (3) and marfey's (5) methods, respectively. compounds 3-5 showed inhibitory effects on hiv ...	2009	19919067
