Brief Description

MRTX1257 (MRTX-1257, MRTX 1257) is a potent, selective, covalent and irreversible inhibitor of KRAS G12C.
Description

MRTX1257 (MRTX-1257, MRTX 1257) is a potent, selective, covalent and irreversible inhibitor of KRAS G12C, inhibits KRAS dependent ERK-phosphorylation in the H358 cell with IC50 of 0.9 nM; demonstrates high selectivity toward the Cys12 of KRAS G12C in NCI-H358 cells, without effect on other free cysteine residues; shows sustained regression at 3,10, 30, and 100 mg/kg dose in MIA PaCa-2 xenografts, shows rapid growth inhibition and durable efficacy even after dosing was stopped, and MRTX1257 is orally acitve.
