Therefore, the development of SHP2 inhibitors has attracted extensive attention. In this study, based on the known inhibitor 1 (SHP099), novel SHP2 inhibitors were designed by means of scaffold hopping, and 35 pyridine derivatives as SHP2 inhibitors were found. The in vitro enzyme activity assay was performed on these compounds, and multiple selective SHP2 inhibitors with activity potency similar to
SHP2是由PTPN11基因编码的非受体蛋白酪氨酸磷酸酶,它影响多种信号通路的传导,包括RAS-ERK,PI3K-AKT和JAK-STAT。SHP2在程序性细胞死亡途径(PD-1 / PD-L1)中也起着重要作用。研究表明,SHP2与多种癌症有关,包括乳腺癌,肝癌和胃癌。因此,SHP2抑制剂的开发引起了广泛的关注。在这项研究中,基于已知的抑制剂1(SHP099),通过支架跳跃设计了新型SHP2抑制剂,发现了35种吡啶衍生物作为SHP2抑制剂。对这些化合物进行了体外酶活性测定,获得了具有与SHP099相似的活性的多种选择性SHP2抑制剂。其中,化合物(2-(4-(氨基甲基)哌啶-1-基)-5-(2,3-二氯苯基)吡啶-3-基)甲醇(11a)是最有效和选择性最高的体外酶SHP2抑制剂活性IC50值为1.36μM。荧光滴定法验证了11a直接与SHP2蛋白结合。随后,代表性化合物的细胞测定表明这些化合物可以有效抑制Ba
