XVIth National Days of Biology. Lyon, 6-7 June 1997

Two new benzoquinones with antifungal, antibacterial, and cytotoxic activities have been isolated from liquid cultures of the coprophilous fungus Podospora anserina. The structures of anserinones A (1) and B (2) were assigned on the basis of MS and NMR results, and the absolute stereochemistry of 2 was deduced by analysis of 1H-NMR data for its (R)- and (S)-2-phenylbutyryl ester derivatives.
