Discovery of a potent and selective series of pyrazole bacterial methionyl-tRNA synthetase inhibitors

Bioorg Med Chem Lett. 2003 Jul 7;13(13):2231-4. doi: 10.1016/s0960-894x(03)00298-1.

Abstract

Starting with a micromolar lead identified from high-throughput screening, a series of pyrazoles were discovered with significantly improved potency on bacterial methionyl-tRNA synthetase and selectivity over human methionyl-tRNA synthetase.
