A new antifungal polyketide, named hakuhybotric acid (1), was isolated from a cultured broth of a mycoparasitic fungus Hypomyces pseudocorticiicola FKI-9008, together with two known analogs, F2928-1 (2) and Cladobotric acid E (3). Their structures were elucidated by MS and NMR analyses. The structure of hakuhybotric acid was the two epoxy groups of F2928-1 converted to olefins. All compounds showed antifungal activity against four different species of Aspergillus spp., the causative agents of aspergillosis. It was suggested that mycoparasitic fungi are a useful source to search antifungal drug lead compounds.
