==Overview==
==Overview==
IMP-1 metallo-beta-lactamase (class B) is a plasmid-borne zinc, metalloenzyme that efficiently hydrolyzes beta-lactam antibiotics, including carbapenems, rendering them ineffective. Because IMP-1 has been, found in several clinically important carbapenem-resistant pathogens, there is a need for inhibitors of this enzyme that could protect broad, spectrum antibiotics such as imipenem from hydrolysis and thus extend, their utility. We have identified a series of 2,3-(S,S)-disubstituted, succinic acids that are potent inhibitors of IMP-1. Determination of high, resolution crystal structures and molecular modeling of succinic acid, inhibitor complexes with IMP-1 has allowed an understanding of the, potency, stereochemistry, and structure-activity relationships of these, inhibitors.
