Structure-based design, synthesis and biological evaluation of aminopyrazines as highly potent, selective, and cellularly active allosteric SHP2 inhibitors

Eur J Med Chem. 2022 Feb 15;230:114106. doi: 10.1016/j.ejmech.2022.114106. Epub 2022 Jan 12. Kai Tang 1, Min Zhao 1, Ya-Hong Wu 2, Qiong Wu 1, Shu Wang 1, Yu Dong 2, Bin Yu 3, Yihui Song 4, Hong-Min Liu 5 Abstract Src homology-2-containing protein tyrosine phosphatase 2 (SHP2) encoded by the proto-oncogene PTPN11 is the first identified non-receptor protein tyrosine phosphatase. SHP2 dysregulation contributes to the pathogenesis of different cancers, making SHP2 …
