CI-1033 (Canertinib) is an orally bioavailable irreversible Pan-erbB tyrosine kinase inhibitor, targeting EGFR with IC50 of 0.8, 19 and 7 nM for EGFR, HER-2 and ErbB-4, respectively. It effectively inhibits the growth of esophageal squamous cell carcinoma which co-expresses both EGFR and HER2 with the inhibition of phosphorylation of both MAPK and AKT. inhibitor, is a clinically promising agent that is active against all four members of the erbB receptor tyrosine kinase family. In vitro studies of human cancer cell lines indicate that CI-1033 results in prompt, potent, and sustained inhibition of tyrosine kinase activity. This inhibition is highly selective for erbB1 (epidermal growth factor receptor), erbB2, erbB3, and erbB4 without inhibiting tyrosine kinase activity of receptors such as platelet-derived growth factor receptor, fibroblast growth factor receptor, and insulin receptor, even at high concentrations.

| After starved in serum-free medium for 24h, Breast cancer cells incubated with the indicated concentrations of CI-1033 for 3h,followed by 15-minute stimolation of 100ng/ml EGF
| |
| H1975 cells were pretreated with 10nm EGF for 15 min and then treated with the indicated concentrations of CI-1033 for 2 hours.
| |
| LNCaP-AI cells were starved in 1% stripped medium for 24 h. The cells were then treated with Erlotinib (20 lM), Gefitinib (20 lM), Lapatinib (20 lM), CI-1033 (8 lM), LY294002 (20 lM) and Bortezomib (20 lM) for 24 h. Cell culture medium was collected from each sample and subjected to ELISA for sPLA2-IIa. The condition medium samples were diluted 10 times for ELISA. Average of duplicate samples was converted to nanogram per milliliter against standard curve. The data represent one of five repeated experiments.

| (B–C) LNCaP (B) and LNCaP-AI (C) cells were transiently transfected with sPLA2-IIa(-800)-Luc (0.5 lg). The cells were then treated with Erlotinib (20 lM), Gefitinib (20 lM), Lapatinib (20 lM), CI-1033 (8 lM), LY294002 (20 lM) and Bortezomib (20 lM) without or with EGF (100 ng/ml) for 24 h. Luciferase assay was performed according to a standard protocol with Renilla luciferase as an internal control. Data are presented as the mean (±SD) of duplicate values of a representative experiment that was independently repeated for five times. |
