产品描述:
Ceritinib is an inhibitor of anaplastic lymphoma kinase (ALK; IC50 = 0.2 nM).{48716} It is selective for ALK over IGF-1R, InsR, STK22D, and FLT3 (IC50s = 8, 7, 23, and 60 nM, respectively) as well as a panel of 25 additional kinases (IC50s = >0.26 μM for all). Ceritinib inhibits the proliferation of Ba/F3 cells expressing the fusion protein nucleophosmin-ALK (NPM-ALK) or echinoderm microtubule-associated protein-like 4-ALK (ELM4-ALK; IC50s = 0.02 and 0.021 μM, respectively), as well as several crizotinib-resistant NPM-ALK and ELM4-ALK mutants.{31295} It reduces tumor growth in an H2228 non-small cell lung cancer (NSCLC) rat xenograft model when administered at a dose of 10 mg/kg per day and induces tumor regression at 25 mg/kg per day.{48716} Ceritinib (25 and 50 mg/kg per day) also induces tumor regression in a Karpas299 lymphoma rat xenograft model. Formulations containing ceritinib have been used in the treatment of ALK-positive metastatic NSCLC.
