WF11899A, B and C, novel antifungal lipopeptides. I. Taxonomy, fermentation, isolation and physico-chemical properties.

Abstract

WF11899A, B and C, novel antifungal lipopeptide antibiotics were isolated from the culture broth of Coleophoma empetri F-11899. These compounds belong to the echinocandin type of lipopeptides. Of these compounds, WF11899A showed good solubility in water. These three antibiotics possess potent in vitro antifungal activities against Candida spp.
