3-(2-cyanopropan-2-yl)-N-[4-methyl-3-[(3-methyl-4-oxo-6-quinazolinyl)amino]phenyl]benzamide is a member of benzamides.
AZ 628 (AZ-628; AZ628) is a research-grade pan-RAF kinase inhibitor, designed to target both mutant (BRAFⁿᵉᵗ/ᵛ⁶⁰⁰ᴱ) and wild-type (BRAFʷᵗ, CRAF) RAF kinases for the treatment of RAF/MAPK-driven cancers. It is not approved for clinical use [1,2] - Mechanism of Action: Its antitumor effect is mediated by inhibiting RAF kinase activity, blocking the downstream MAPK (RAF-MEK-ERK) signaling pathway—this pathway is constitutively activated in cancers with KRAS/BRAF mutations, driving cell proliferation and survival [1,2] - Genotype Selectivity: AZ 628 (AZ-628; AZ628) exhibits preferential activity against KRAS/BRAF-mutant cancer cells, with minimal toxicity to normal cells, supporting its potential as a genotype-directed therapeutic agent [2] - Research Applications: It is widely used in preclinical studies to investigate RAF family biology, MAPK pathway activation in mutant cancers, and to validate combination strategies (e.g., with MEK inhibitors) to overcome RAF inhibitor resistance [1,2] |
