Abstract

4'-Deoxy derivatives of neospiramycin I and their 12-(Z)-isomers were synthesized by reductive dechlorination via 4'-epi-chloro derivatives. The 12-(Z)-derivatives were more active against bacteria in vitro than the corresponding 12-(E)-derivatives in spite of their low affinities to ribosomes.

摘要

通过4'-表氯衍生物的还原脱氯反应合成了新螺旋霉素I的4'-脱氧衍生物及其12-(Z)-异构体。尽管12-(Z)-衍生物对核糖体的亲和力较低,但它们在体外对细菌的活性比相应的12-(E)-衍生物更高。
