reported the identification of compound 1 as SHP2 inhibitor. Fragment-based ligand design, De novo design, ADMET and Molecular docking were performed to explore potential selective SHP2 allosteric inhibitors based on SHP836. The results of docking studies indicated that the selected compounds had higher selective SHP2 inhibition than existing inhibitors. Compound 1 was found to have a novel selectivity
PTPN11基因编码的SHP2磷酸酶是一种非受体PTP,在生长因子,细胞因子,整联蛋白,激素信号传导途径中起着重要作用,并调节细胞反应,例如增殖,分化,粘附迁移和凋亡。许多研究报告说,SHP2表达的上调与人类癌症(如乳腺癌,肝癌和胃癌)密切相关。因此,SHP2已成为癌症免疫疗法的有希望的靶标。在本文中,我们报道了化合物1作为SHP2抑制剂的鉴定。进行了基于片段的配体设计,从头设计,ADMET和分子对接,以探索基于SHP836的潜在选择性SHP2变构抑制剂。对接研究的结果表明,所选化合物比现有抑制剂具有更高的选择性SHP2抑制作用。发现化合物1具有针对SHP2的新选择性,其体外酶活性IC50值为9.97μM。荧光滴定实验证实化合物1直接与SHP2结合。此外,结合自由能的结果表明,静电能是阐明SHP2抑制机理的主要因素。动态互相关研究也支持对接和分子动力学模拟的结果。这一系列分析为设计新的选择
