demonstrated that the benzothiazole benzimidazole forms bi-dentate H-bonds to Asp48, and the benzothiazole interacts with the surface of the protein in a solvent exposed region towards the C-site. The design, synthesis, and SAR of this novel series of benzothiazole benzimidazole containing (S)-IZD inhibitors of PTP1B are presented herein.
通过三肽(S)-IZD蛋白酪氨酸磷酸酶1B(PTP1B)抑制剂1的拟肽修饰,发现了苯并噻唑苯并咪唑(S)-异噻唑烷酮((S)-IZD)衍生物5。这些衍生物是有效,竞争和可逆的抑制剂。具有改善的caco-2渗透性的PTP1B的制备。抑制剂5 / PTP1B在2.2A分辨率下的X射线共晶体结构表明,苯并噻唑苯并咪唑与Asp48形成双齿H键,并且苯并噻唑在溶剂暴露区域向C处与蛋白质表面相互作用。 -地点。本文介绍了该新型系列的含PTP1B的(S)-IZD抑制剂的苯并噻唑苯并咪唑的设计,合成和SAR。
