A new series of 1β-methylcarbapenems 1a—d bearing 5-methyl-4-mercaptopyrrolidinone rings has been prepared and evaluated for in vitro antibacterial activity and pharmacokinetic parameters. Most compounds showed excellent antibacterial activity and high stability to dehydropeptidase-1. We have synthesized optically active 5-methyl-4-hydroxypyrrolidinones from enantiomerically pure aziridine esters.
一系列带有5-甲基-4-巯基吡咯烷酮环的1β-甲基碳青霉烯类化合物1a—d已经被合成并评估了其体外抗菌活性和药代动力学参数。大多数化合物表现出了卓越的抗菌活性和对去氢肽酶-1的高稳定性。我们已经从手性纯的氮杂环丙烷酯合成了光学活性的5-甲基-4-羟基吡咯烷酮。
