Protein tyrosine phosphatase 1B (PTP1B) acts as a negative regulator of insulin and leptin signalling and is crucially involved in the development of type 2 diabetes mellitus, obesity, cancer and neurodegenerative diseases. Pursuing our efforts to identify PTP1B inhibitors endowed with drug-like properties, we designed and evaluated 3-aryl-5-arylidene-2-thioxo-4-imidazolidinones (7) as a novel class
蛋白质酪氨酸磷酸酶1B(PTP1B)充当胰岛素和瘦素信号传导的负调节剂,并且在2型糖尿病,肥胖症,癌症和神经退行性疾病的发展中起着至关重要的作用。为了确定具有类似药物性质的PTP1B抑制剂,我们设计并评估了3-芳基-5-芳基-2-硫代氧-4-咪唑啉酮(7)作为一类新型的非羧酸盐PTP1B抑制剂。与我们的设计一致,动力学研究表明所选化合物7在低微摩尔浓度下可作为目标酶的可逆,非竞争性抑制剂。因此,分子对接实验表明,这些抑制剂可以适合我们先前个体化的PTP1B的变构位点。而且,细胞测定法证明化合物7e在人肝HepG2细胞中起有效的胰岛素敏化剂的作用。综上所述,我们的结果表明,这些非竞争性PTP1B抑制剂可以被认为是有前途的先导化合物,旨在增强靶酶的可成药性并鉴定新的抗糖尿病药。
