  Design, synthesis, and biological evaluation of novel 2-ethyl-5-phenylthiazole-4-carboxamide derivatives as protein tyrosine phosphatase 1B inhibitors with improved cellular efficacy

  摘要：

  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-ethy1-5-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 IRP and Akt as well as the rate of glucose uptake. (C) 2013 Elsevier Masson SAS. All rights reserved.

  PTP1B inhibitors with the following structure (formula I). Experiments indicate that these inhibitors can effectively inhibit the activity of protein tyrosine phosphatase 1B (PTP1B). They can be used as insulin sensitisers. They can be used to prevent, delay or treat diseases which are related to insulin antagonism mediated by PTP1B, especially diabetes type II and obesity. The invention also provides methods for preparing these inhibitors.
