生物活性:
CEP-28122 mesylate salt, a diaminopyrimidine derivative, is a potent, selective, and orally bioavailable ALK inhibitor, with an IC50 value of 1.9 nM for recombinant ALK kinase activity. CEP-28122 has antitumor activity in experimental models of ALK-positive human cancers. CEP-28122 mesylate salt has good pharmacodynamic and pharmacokinetic activity.

体内研究:
CEP-28122 mesylate salt (3-30 mg/kg; oral gavage; twice a day; 12 days) produces dose-dependent antitumor activity in Sup-M2 subcutaneous tumor xenografts in SCID mice.In contrast, CEP-28122 has no antitumor activity in nu/nu mice bearing HCT116, suggesting that the antitumor activity of CEP-28122 in NPM-ALK–positive Sup-M2 tumor models is due to sustained NPM-ALK inhibition in tumors .Animal Model:Female SCID mice bearing Sup-M2 subcutaneous tumor xenografts and nu/nu mice bearing HCT116 aged 6-8 week old
Dosage:3 mg/kg, 10 mg/kg and 30 mg/kg
Administration:oral gavage; twice a day; 12 days
Result:CEP-28122 produced dose-dependent antitumor activity in Sup-M2 subcutaneous tumor xenografts in SCID mice. In contrast, CEP-28122 had no antitumor activity in nu/nu mice bearing HCT116.

体外研究:
CEP-28122 mesylate salt (3-3000 nM; 48 hours) treatment leads to concentration-dependent growth inhibition of Karpas-299 and Sup-M2 cells in culture, associates with concentration-related caspase 3/7 activation. CEP-28122 mesylate salt (30-1000 nM; 2 hours) treatment leads to substantial suppression of phosphorylation of putative downstream effectors of ALK in Sup-M2 cells, indicating that the downstream signaling pathways are mediated by individual ALK fusion protein.
