Abstract

4,7-Dichloro-1-benzothien-2-yl sulfonylaminomethyl boronic acid (DSABA, Compound I) was discovered as the first boronic acid-based class D beta-lactamase inhibitor. It exhibited an IC(50) of 5.6 microM against OXA-40. The compound also inhibited class A and C beta-lactamases with sub to low microM IC(50), and synergized with imipenem against Acinetobacter baumannii.Copyright 2010 Elsevier Ltd. All rights reserved.
