The title congeners were synthesized by employing our efficient synthetic route previously explored for preparing enantiomeric pairs of thiolactomycin and its 3-demethyl derivative. While all the synthesized congeners lacked in vitro antibacterial activity, some of the congeners bearing an (E)-cyclohept-2-enylidenemethyl or an (E)-cyclooct-2-enylidenemethyl group were found to exhibit more potent type
通过使用我们先前探索的用于制备硫菌霉素及其3-脱甲基衍生物的对映异构体对的有效合成途径,合成了标题同源物。虽然所有合成的同类物均缺乏体外抗菌活性,但发现一些带有(E)-环庚-2-烯基甲基或(E)-环辛-2-烯基甲基的同类物比Is FAS具有更强的抑制活性(S)-3-demethylthiolactomycin具有非天然构型。
