  Semi-synthesis and biological evaluation of analogues of UK-2A, a novel antifungal antibiotic from Streptomyces sp. 517-02

  摘要：

  Several analogues of UK-2A, a novel antifungal antibiotic isolated from Streptomyces sp. 517-02, were semi-synthesized for structure-activity studies. In vitro antifungal activities of these compounds against Saccharomyces cerevisiae IFO 0203 were evaluated by the conventional paper disk method. Several derivatives exhibited growth inhibitory activity similar to UK-2A. (c) 2005 Elsevier Ltd. All rights reserved.
