Biological Activity
AP26113 is an orally-available, potent, and selective inhibitor of ALK with a potency of 0.62 nM against wild-type and activity against a wide range of mutants, including the crizotinib-resistant L1196M line. In a panel of EML4-ALK or NPM-ALK-positive cell lines, AP26113 has IC50 values of 4-31 nM. [1][2]
AP26113 is effective against sensitive and resistant H3122 cells, reducing cell growth, suppressing ALK phosphorylation, and inducing apoptosis. In Ba/F3 cells expressing native or mutant EML4-ALK, AP26113 was active at IC50s of 10 and 24 nM, respectively. [3]
