prepared, it appeared evident that in vitro antibacterial and mammalian type I FAS inhibitory activity of thiolactomycin congeners can be cleanly separated by changing not only the structure but also the absolute configuration of the side chain at the C(5)-position. These studies led us to explore (S)-3-demethyl-5-(pent-1-enyl)thiolactomycin derivative [(S)-4-hydroxy-5-methyl-5-(pent-1-enyl)-5H-thiophen-2-one]
通过使用我们先前探索的用于合成硫菌丝霉素及其3-脱甲基衍生物的对映体对的有效合成路线,合成了十二个5-乙烯基硫基乳酸霉素同系物的对映体对。从使用获得的同源物以及先前制备的对映体对的硫菌霉素及其3-脱甲基衍生物进行的生物活性分析,似乎可以看出,通过不改变不仅是侧链在C(5)位置的结构而且是绝对构型。
