Abstract
Protein tyrosine phosphatase 1B (PTP1B) is a key negative regulator of insulin signaling pathway. Inhibition of PTP1B is expected to improve insulin action. Appropriate selectivity and permeability are the gold standard for excellent PTP1B inhibitors. In this work, molecular hybridization-based screening identified a selective competitive PTP1B inhibitor. Compound 10a has IC50 values of 199 nM against PTP1B, and shows 32-fold selectivity for PTP1B over the closely related phosphatase TCPTP. Molecule docking and molecular dynamics studies reveal the reason of selectivity for PTP1B over TCPTP. Moreover, the cell permeability and cellular activity of compound 10a are demonstrated respectively.

Abstract
Protein tyrosine phosphatase 1B (PTP1B) is implicated as a key negative regulator of the insulin and leptin signal-transduction pathways. PTP1B inhibitors have emerged as attractive and potent pharmaceutical agents for the treatment of type 2 diabetes and obesity. We identified a series of 2-ethyl-5-phenylthiazole-4-carboxamide (PTA) derivatives, inspired from the ACT scaffold of Scleritodermin A, as a novel class of PTP1B inhibitors. Structure-activity relationship (SAR) analysis and docking studies revealed the molecular basis of PTP1B inhibition by these compounds. PTA derivative 18g was capable of inhibiting intracellular PTP1B and subsequently activating the insulin signaling pathway. Treatment of cells with 18g markedly increased the phosphorylation levels of IRβ and Akt as well as the rate of glucose uptake.
