The synthesis and biological activity of a novel series of 2-alkyl-4-pyrrolidinylthio-beta-methylcarbapenems containing a variety of cationic heteroaromatic substituents is described. As a result of these studies, we uncovered a relationship between in vitro antibacterial activity and the length of the alkyl spacer part, and discovered FR20950 (1c), containing a two methylene spacer moiety and an imidazolio
描述了含有各种阳离子杂芳族取代基的一系列新的2-烷基-4-吡咯烷基硫基-β-甲基卡巴南的合成和生物活性。这些研究的结果是,我们发现了体外抗菌活性与烷基间隔部分长度之间的关系,并发现了含有两个亚甲基间隔部分和一个咪唑基团的FR20950(1c),该基团具有均衡的抗菌谱活性,包括铜绿假单胞菌和耐甲氧西林的金黄色葡萄球菌(MRSA)。此外,FR20950表现出出色的尿液恢复能力,并且与比阿培南相比具有相对于肾脏脱氢肽酶-I(DHP-1)相当的稳定性。通过在咪唑环上引入取代基可以改善DHP-1的稳定性。
