A patent review of SHP2 allosteric inhibitors (2018-present).
Introduction: SHP2 (Src homology region 2-containing protein tyrosine phosphatase 2) is a target of interest for cancer therapy due to its key role in the regulation of the RAS/MAPK signal transduction pathway downstream of Receptor Tyrosine Kinases (RTKs). Moreover, SHP2 can inhibit T cells via the PD-1/PD-L1 pathway. SHP2 plays a critical role in numerous physiological and pathological cellular processes, such as cell proliferation, survival, and migration.
Areas covered: This review examines SHP2 allosteric inhibitors reported in patents published in Espacenet and Scifinder databases from 2018 to present. An overview of claimed structures is conducted, focusing attention on structural modifications compared to SHP099, the first described allosteric inhibitor of SHP2.
Expert opinion: Multiple potent allosteric SHP2 inhibitors have been discovered, disclosed, and tested in a variety of preclinical cancer models with strong evidence of efficacy. Fifteen compounds are currently in clinical development, but none of them have been approved for marketing. Until now, long-term benefit of SHP2 inhibitors as monotherapy agents have not been demonstrated due to acquired mechanisms of resistance and/or lack of efficacy. However, combination therapies with a variety of agents, such as MEK, BRAF, EGFR, RAS-G12C and PDL-1 inhibitors, have high potential and are currently an extensive area of investigation.
