AMG-510 selectively forms an irreversible covalent bond to the sulfur atom in the cysteine residue that is present in the mutated form of KRAS, but not in the normal form. KRASG12C can be targeted with covalent small molecule inhibitor AMG-510 which react with the mutant cysteine adjacent to the switch II pocket (SIIP), locking KRAS in its inactive GDP-bound state[1].
