Antimicrobial resistance was first reported in 1940 soon after the discovery of beta-lactam antibiotics in 1929. Since then, antimicrobial resistance is a rising global health threat and discovery of new drugs targeting different mechanisms of pathogenesis is an area of intense research. One mechanism of bacterial resistance is expression of the beta-lactamase protein, which hydrolyzes beta-lactam antibiotics rendering them ineffective. Despite the presence of some commercial inhibitors, beta-lactamases are continuously evolving and beta-lactamase continues to be an important drug target. I will talk about our recent work on fighting with beta-lactamase producing resistant bacteria. First, I will discuss our efforts on understanding beta-lactamase binding dynamics. I will describe the design and discovery of a beta-lactamase inhibitory peptide with antimicrobial and uptake properties. Last, I will describe our latest research on following beta-lactamase evolution using a ligand-centric network.
