title: New verticillin and glisoprenin analogues from gliocladium catenulatum, a mycoparasite of aspergillus flavus sclerotia
abstract: Four new compounds (1-4) have been isolated from solid-substrate fermentation cultures of the sclerotial mycoparasite Gliocladium catenulatum. The structures of verticillins D (1), E (2), and F (3) were assigned on the basis of MS and NMR data and chemical derivatization. The structure of glisoprenin F (4) was assigned by analysis of MS and NMR results, and comparison of its spectral data to those of the known compound glisoprenin D (6).
