BioAssay: AID 638647

Inhibition of Pseudomonas aeruginosa beta-lactamase IMP-1 expressed in Escherichia coli BL21(DE3) at 1000 uM using CENTA as chromogenic substrate

The production of beta-lactamases is an effective strategy by which pathogenic bacteria can develop resistance against beta-lactam antibiotics. While inhibitors of serine-beta-lactamases are widely used in combination therapy with beta-lactam antibiotics, there are no clinically available inhibitors of metallo-beta-lactamases (MBLs), and so there is a need for the development of such inhibitors. more ..

Title: 3-mercapto-1,2,4-triazoles and N-acylated thiosemicarbazides as metallo-beta-lactamase inhibitors.

Abstract: The production of beta-lactamases is an effective strategy by which pathogenic bacteria can develop resistance against beta-lactam antibiotics. While inhibitors of serine-beta-lactamases are widely used in combination therapy with beta-lactam antibiotics, there are no clinically available inhibitors of metallo-beta-lactamases (MBLs), and so there is a need for the development of such inhibitors. This work describes the optimisation of a lead inhibitor previously identified by fragment screening of a compound library. We also report that thiosemicarbazide intermediates in the syntheses of these compounds are also moderately potent inhibitors of the IMP-1 MBL from Pseudomonas aeruginosa. The interactions of these inhibitors with the active site of IMP-1 were examined using in silico methods.
