Synthesis of new tricyclic carbapenems (trinems) with a pyrrolidinyl moiety at the C-4 position of the tricyclic ring and their antimicrobial activities were studied. These trinems showed potent activities against Gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA). Among them, (4R)-[(S)-pyrrolidin-3-ylthiomethyl]trinem (14a) exhibited good activity against MRSA in vitro and in vivo.
研究了在三环的 C-4 位上含有吡咯烷基分子的新型三环碳青霉烯类化合物(trinems)的合成及其抗菌活性。这些三烯类化合物对革兰氏阳性细菌(包括耐甲氧西林金黄色葡萄球菌(MRSA))具有很强的抗菌活性。其中,(4R)-[(S)-吡咯烷-3-基硫甲基]三嗪(14a)在体外和体内对 MRSA 均表现出良好的活性。
