摘要:
                                Sordaricin analogues possessing 6-methoxy-7-methyl-1,4-oxazepane moiety instead of the sugar part were synthesized and evaluated. It was found that N-substituents on the oxazepane ring had influence on biological activity. In particular, N-(2-methylpropenyl) derivative 12p exhibited potent in vitro antifungal activity. Furthermore, 12p maintained significant activity (MIC 0.25 mug/mL) against Candida albicans SANK51486 even in the presence of 20% horse serum. (C) 2002 Elsevier Science Ltd. All rights reserved.
