The synthesis, antibacterial activity and stability to human dehydropeptidase-1 (DHP-1) of three small series of carbapenems carrying carbon-linked substituents at C-2 are described. C-2 Ethenyl carbapenems showed moderate antibacterial activity but poor stability to DHP-1. C-2 Oxyiminomethyl carbapenems demonstrated variable activity and stability. C-2 α-(Hydroxy)benzyl carbapenems were the most promising and showed good potency and DHP-1 stability.
描述了三系列在C-2位带有碳链取代基的碳青霉烯类化合物的合成、抗菌活性及其对人类脱氢肽酶-1(
DHP-1)的稳定性。C-2位的
乙烯基碳青霉烯显示出中等的抗菌活性,但对
DHP-1的稳定性较差。C-2位的羟
亚胺甲基碳青霉烯表现出可变的活性和稳定性。C-2位的α-(羟基)苯甲基碳青霉烯是最有前途的,显示出良好的效力和对
DHP-1的稳定性。
