Structure-based design of beta-lactamase inhibitors. 2. Synthesis and evaluation of bridged sulfactams and oxamazins.

摘要

A series of bridged monocyclic beta-lactams activated by various groups on the beta-lactam nitrogen (X = OCH2CO2H, OSO3H) has been synthesized and evaluated. Among them, the bridged sulfactams (X = OSO3H) were found to be effective beta-lactamase inhibitors. They inhibit both class A and class C beta-lactamases.
