Product Overview
ASP3026 is a selective inhibitor of ALK with IC50 value of 3.5 nM. ASP3026 is a potent ALK inhibitor and has a different selectivity with the reported ALK inhibitor crizotinib. When tested with a panel of 86 tyrosine kinases, ASP3026 showed the highest selectivity for ALK, ROS and ACK kinases. In NCI-H2228 NSCLC cells expressing EML4-ALK, five-day treatment of ASP3026 resulted in a cell growth inhibition with IC50 value of 64.8 nM. ASP3026 also inhibited the viability of NPM-ALK+ ALCL cells with IC50 values of 0.4, 0.75, 1 and 2.5 µM in SU-DHL-1, SUP-M2, SR-786 and Karpas 299 cells, respectively. In mouse model with NCI-H2228 subcutaneous xenograft, oral administration of ASP3026 caused significant reduction of phosphorylated ALK and tumor growth. 30 mg/kg/d ASP3026 for 2 weeks induced tumor regression by 78%. In mice injected with Karpas 299 cells, ASP3026 treatment caused remarkable lymphoma regression.
