Structure-based design led to the discovery of novel (S)-isothiazolidinone ((S)-IZD) heterocyclic phosphotyrosine (pTyr) mimetics that when incorporated into dipeptides are exceptionally potent, competitive, and reversible inhibitors of protein tyrosine phosphatase 1B (PTP1B). The crystal structure of PTP1B in complex with our most potent inhibitor 12 revealed that the (S)-IZD heterocycle interacts
基于结构的设计导致发现了新型(S)-异噻唑烷酮((S)-IZD)杂环磷酸酪氨酸(pTyr)模拟物,该模拟物掺入二肽时是蛋白质酪氨酸磷酸酶1B(PTP1B)的异常有效,竞争性和可逆抑制剂。与我们最有效的抑制剂12配合使用的PTP1B的晶体结构表明,(S)-IZD杂环可与硅酸盐结合环精确地相互作用,正如计算机设计的那样。我们的数据提供了有力的证据,表明(S)-IZD是迄今为止报道的最有效的pTyr模拟物。
