How to use
MRTX1257 demonstrates rapid, irreversible modification of GDP-bound recombinant KRAS G12C and suppresses ERK phosphorylation with an IC50 = 1 nM in the H358 cell line. In proteomics studies designed to assess global protein modification, MRTX1257 is shown to be highly selective for the targeted Cys12 of KRAS G12C versus other surface-exposed cysteine residues in NCI-H358 cells.
MRTX1257 exhibits 31% bioavailability in mouse, demonstrates near-complete inhibition of KRAS signaling in tumor tissue, and complete durable tumor regression in MIA PaCa-2 xenografts.
