产品介绍
Canertinib (CI-1033) (CI-1033;PD-183805) 是一种有效且不可逆的 EGFR 抑制剂;抑制细胞 EGFR 和 ErbB2 自磷酸化,IC50 为 7.4 和 9 nM。

Kinase experiment:

Enzyme assays for IC50 determinations are performed in 96-well filter plates. The total volume is 0.1 mL containing 20 mM Hepes, pH 7.4, 50 mM sodium vanadate, 40 mM magnesium chloride, 10 μM adenosine triphosphate (ATP) containing 0.5 mCi of [32P]ATP, 20 mg of polyglutamic acid/tyrosine, 10 ng of EGFR tyrosine kinase, and appropriate dilutions of inhibitor (Canertinib). All components except the ATP are added to the well and the plate is incubated with shaking for 10 min at 25℃. The reaction is started by adding [32P]ATP, and the plate is incubated at 25℃ for 10 min. The reaction is terminated by addition of 0.1 mL of 20% trichloroacetic acid (TCA). The plate is kept at 4℃ for at least 15 min to allow the substrate to precipitate. The wells is then washed five times with 0.2 mL of 10% TCA and 32P incorporation determined with a plate counter[1].

Cell experiment:

RaH3 and RaH5 cells are treated with increasing concentrations (0-10 μM) of Canertinib for 72 h. The cells are suspended in buffer and counted[2].

Animal experiment:

Mice: Canertinib treatment starts when the tumors show reliable growth. The mice are randomized into control and treatment groups. In the canertinib treated RaH3 group (n=4) and RaH5 group (n=7) each mouse receives i.p. injections of 1.2 mg canertinib (40 mg/kg/day) in 0.1 ml 0.15 M NaCl 5 days a week. The control RaH3 (n=3) and RaH5 (n=7) mice receive i.p. injections of vehicle only according to the same regimen. At the end of the treatment period, the mice are sacrificed by cervical dislocation where after the tumors are removed and weighed[2].

产品描述

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].
