Canertinib (CI-1033)
Canertinib (also known as CI-1033), a 3-chloro, 4-fluoro, 4-anilinoquinazoline, is an orally available, potent and irreversible Pan-erbB tyrosine kinase inhibitor that inhibits EGFR, HER2 and HER4 in vitro with the half maximal inhibition concentration IC50 of 0.8 nM, 19 nM and 7 nM respectively [1].
Canertinib irreversibly binds into the ATP pocket within the TK domain of all erbB family members, where the acrylamide side-chain at position C6 of canertinib is brought into close proximity with cysteines of erbB members, followed by the rapid formation of a covalent bond, which permanently inactivates the catalytically active erB1, erB2 and erB4 family members and effectively inhibits erbB3-dependent signaling [2].
