描述 | SHP099 is a highly potent and selective SHP2 inhibitor that can be administered orally, exhibiting an IC50 of 70 nM. The X-ray co-crystal structure of SHP099 bound to SHP2 unveils a novel interaction between the basic amine and the Phe113 backbone carbonyl. SHP099 demonstrates an ability to inhibit cell proliferation in the KYSE-520 model with an IC50 of 1.4 μM. Additionally, SHP099 is characterized by its high solubility and permeability, without significant efflux in Caco-2 cells[1]. SHP099 simultaneously interacts with the interfaces of the N-terminal SH2, C-terminal SH2, and protein tyrosine phosphatase domains, thereby allosterically inhibiting SHP2 activity. It also impedes RAS–ERK signaling, which is crucial in halting the proliferation of human cancer cells driven by receptor tyrosine kinases[2]. |
Animal study | Following administration of a single dose at 30 mg/kg and 100 mg/kg, a dose-responsive relationship is evident in the exposure and modulation of the pharmacodynamic biomarker p-ERK within the xenografts. Administering a daily oral dose of 10 mg/kg or 30 mg/kg results in tumor growth inhibition of 19% and 61%, respectively. Complete tumor stasis is observed with a daily dose of 100 mg/kg[1]. |
