Protein tyrosine phosphatase 1B (PTP1B) is a negative regulator of the insulin and leptin receptor pathways and thus an attractive therapeutic target for diabetes and obesity. Starting with a high micromolar lead compound, structure-based optimization of novel PTP1B inhibitors by extension of the molecule from the enzyme active site into the second phosphotyrosine binding site is described.

蛋白酪氨酸磷酸酶1B(PTP1B)是胰岛素和瘦素受体途径的负调节剂,因此是糖尿病和肥胖症的有吸引力的治疗靶标。从高微摩尔的先导化合物开始,描述了通过将分子从酶活性位点延伸到第二个磷酸酪氨酸结合位点来对新型PTP1B抑制剂进行基于结构的优化。在X射线复合物结构和分子建模的指导下,药物化学已经以有效的方式产生了低纳摩尔PTP1B抑制剂。发现来自该化学系列的化合物被主动转运到肝细胞中。这种对靶组织的主动摄取可能是克服PTP1B抑制剂膜通透性差的可能途径之一。
