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.
Regorafenib is a small molecule inhibitor of multiple membrane-bound and intracellular kinases involved in oncogenesis, tumor angiogenesis, metastasis, and tumor immunity, including VEGFR1-3, KIT, PDGFR-alpha/beta, FGFR1/2, RAF-1, BRAF, and CSF1R.
