structure-based design and discovery of the isothiazolidinone (IZD) heterocycle as a mimic of phosphotyrosine (pTyr) has led to the identification of novel IZD-containing inhibitors of protein tyrosine phosphatase 1B (PTP1B). The structure-activity relationships (SARs) of peptidic IZD-containing inhibitors of PTP1B are described along with a novel synthesis of the aryl-IZD fragments via a Suzuki coupling
基于结构的设计和异噻唑烷酮(IZD)杂环作为磷酸酪氨酸(pTyr)的模拟物的发现,导致鉴定了新型的含IZD的蛋白酪氨酸磷酸酶1B(PTP1B)抑制剂。描述了含肽IZD的PTP1B抑制剂的结构活性关系(SAR),以及通过Suzuki偶联新合成芳基-IZD片段。SAR显示,与不饱和IZD(25),噻二唑烷酮(TDZ)(38)和区域异构不饱和IZD(31)相比,饱和IZD杂环(42)是最有效的杂环pTyr模拟物。解决了与PTP1B复合的11c和25的X射线晶体结构,并揭示了活性位点中几乎相同的结合相互作用。
