Isolation and characterization of two new antifungal antibiotics from a basidiomycete

Two novel antibiotics, Sch 484129 (1) and Sch 484130 (2), were isolated from the fermentation broth of a fungal culture, which was identified as a Basidiomycete. The new antibiotics were obtained by ethyl acetate extraction followed by reversed phase HPLC purification. Structure elucidation of 1 and 2 was accomplished by spectroscopic data analyses. Derivatizations of the major component 1 were performed in order to provide definitive structural information. Both components were identified as glycolipids and displayed antifungal activity against Saccharomyces and Aspergillus strains.
