A series of new carbapenem derivatives, which have a pyrrolidin-4-ylthio group substituted with a hydroxyalkyl or carbamoyl group at the 2' position as the C-2 side chain, have been prepared. The antibacterial activity and the stability to renal dehydropeptidase-I of these compounds were investigated, and the structure-activity relationships were studied. Among these new carbapenems, (1R, 5S, 6S)-2-[(2S, 4S)-2-(2-hydroxy)ethylmercaptomethyl}pyrrolidin-4-ylthio]-6-[(1R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylic acid (1a) showed the most potent and well balanced activity and was selected as a candidate for further evaluation.
一系列新的碳青霉烯衍生物已被制备出来,这些衍生物在C-2侧链位置上具有一个带有羟基烷基或氨甲酰基的吡咯烷-4-基硫醇基团。研究了这些化合物的抗菌活性和对肾脱氢肽酶I的稳定性,并探讨了构效关系。在这些新的碳青霉烯中,(1R, 5S, 6S)-2-[(2S, 4S)-2-(2-羟基)乙硫甲基}吡咯烷-4-基硫]-6-[(1R)-1-羟乙基]-1-甲基-1-碳青霉-2-烯-3-羧酸(1a)显示出最强的且平衡良好的活性,并被选为进一步评估的候选物。
