A series of 1beta-methyl-2-(naphthosultamyl)methyl-carbapenems bearing dicationic groups on the naphthosultamyl moiety was prepared and evaluated for activity against resistant gram-positive bacteria. Based on a combination of excellent in vitro antibacterial activity, acceptable mouse acute toxicity, and a desirable fragmentation pattern on beta-lactam ring opening, the analog 2g (L-786,392) was selected for extended evaluation.
制备了一系列在萘磺酰胺部分带有双阳离子基团的1β-甲基-2-(萘磺酰胺基)甲基碳青霉烯类化合物，并评估了其对耐药革兰氏阳性菌的活性。基于出色的体外抗菌活性、可接受的小鼠急性毒性以及β-内酰胺开环时理想的裂解模式，选择类似物2g（L-786,392）进行进一步评估。
