domain-containing protein tyrosine phosphatase 2 (SHP2) is a non-receptor protein tyrosine phosphatase (PTP) encoded by the PTPN11 gene, which is involved in the RAS/MAPK cell signaling transduction process. SHP2 has been shown to contribute to the progression of various cancers and is emerging as an important target for anti-tumor drug research. However, past efforts to develop SHP2 inhibitors into drugs
Src同源2域含蛋白酪氨酸磷酸酶2(SHP2)是一种由PTPN11基因编码的非受体蛋白酪氨酸磷酸酶(PTP),参与RAS/MAPK细胞信号转导过程。SHP2 已被证明有助于各种癌症的进展,并且正在成为抗肿瘤药物研究的重要目标。然而,过去将 SHP2 抑制剂开发成药物的努力没有成功,因为活性位点口袋的正电荷性质倾向于结合通常非药物样的负电荷基团。在这里,使用基于结构的策略设计和开发了一系列不带电荷的吡唑啉衍生物作为新的 SHP2 抑制剂。化合物4o, 表现出最强的 SHP2 抑制活性, 通过多个氢键以竞争方式直接与 SHP2 的催化结构域结合。化合物4o通过抑制SHP2影响RAS/MAPK信号通路,随后在体外和体内诱导HCT116细胞凋亡和生长抑制。值得注意的是,大剂量口服化合物4o没有表现出明显的毒性。总之,我们的研究结果为进一步开发化合物4o作为一种安全、有效和抗肿瘤的 SHP2 抑制剂提供了基础。
