Biological Activity
IC50: 1.9 nM (ALK), 1 nM (ALKF1174L), 3.5 nM (ALKR1275Q)[1]
Kd: 2.4 nM (ALK)[1]
Alectinib (0-1000 nM; 2 hours; NCI-H2228 cells) treatment could prevent autophosphorylation of ALK in NCI-H2228 cells expressing EML4-ALK, and it also resulted in substantial suppression of phosphorylation of STAT3 and AKT[1].
Alectinib (0-1000 nM; 5 days; HCC827, A549, or NCIH522 cells) treatment reduces cell activity in a dose-dependent manner[1].
