PG - 645-651 LID - 10.1021/acsmedchemlett.3c00059 [doi] AB - Src homology 2-containing protein tyrosine phosphatase 2 (SHP2) is the first reported nonreceptor oncogenic tyrosine phosphatase connecting multiple signal transduction cascades and exerting immunoinhibitory function through the PD-1 checkpoint receptor. As part of a drug discovery program aimed at obtaining novel allosteric SHP2 inhibitors, a series of pyrazopyrazine derivatives bearing an original bicyclo[3.1.0]hexane basic moiety on the left-hand side region of the molecule were identified. We report herein the discovery process, the in vitro pharmacological profile, and the early developability features of compound 25, one of the most potent members of the series.
