Pharmacology
KRAS G12C inhibitor; sotorasib forms an irreversible, covalent bond with the unique cysteine of KRAS G12C, locking the protein in an inactive state that prevents downstream signaling without affecting wild-type KRAS, thereby blocking tumor cell growth and promoting apoptosis in KRAS G12C tumor cell lines.
Dabrafenib is a BRAF kinase inhibitor that targets mutated BRAF V600E, V600K, and V600D enzymes, inhibiting cell growth in BRAF V600 mutation-positive tumors.
