toward expanding the spectrum to allow treatment of a wider range of organisms. Through key structural modifications of a bicyclic lead, stepwise gains in spectrum of inhibition were achieved, ultimately resulting in QPX7728 (35). This compound displays a remarkably broadspectrum of inhibition, including class B and class D enzymes, and is little affected by porin modifications and efflux. Compound

Protein tyrosine phosphatase (PTPase) 1B (PTP1B) has been implicated as a key negative regulator of both insulin and leptin signaling cascades. We identified several salicylic acid-based ligands for the second phosphotyrosine binding site of PTP1B using a NMR-based screening. Structure-based linking with a catalytic site-directed oxalylarylaminobenzoic acid-based pharmacophore led to the identification of a novel series of potent PTP1B inhibitors exhibiting 6-fold selectivity over the highly homologous T-cell PTPase (TCPTP) and high selectivity over other phosphatases.
