MRTX1133 formic

Description

MRTX1133 formic is a noncovalent, potent, and selective KRAS G12D inhibitor. MRTX1133 formic optimally fills the switch II pocket and extends three substituents to favorably interact with the protein, resulting in an estimated KD against KRAS G12D of 0.2 pM. MRTX1133 formic prevents SOS1-catalyzed nucleotide exchange and/or formation of the KRASG12D/GTP/RAF1 complex, thereby inhibiting mutant KRAS-dependent signal transduction. MRTX1133 formic shows efficacy in tumor models harboring KRAS G12D mutations.
