MedKoo CAT#: 207086

CAS#: 2206736-04-9

Description: MRTX1257 is a potent, selective, covalent and irreversible inhibitor of KRAS G12C. MRTX1257 inhibited KRAS dependent ERK phosphorylation in the H358cell assay with an IC50= 900 pM. MRTX1257 demonstrated 31% bioavailability in the mouse, with free fraction exposures well above the cellular potency. In a PK/PD experiment, 77% target engagement.
