Non-carboxylic Acid-Containing Inhibitor of PTP1B Targeting the Second Phosphotyrosine Site
Contents |
Overview
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.
Disease
