KRCA-0008 (0-1000 μM) shows potency to ALK (wt), ALK L1196 M, ALK C1156Y, ALK F1174L, ALK R1275Q and insulin receptor with IC50s of 12, 75, 4, 17, 17 and 210 nM, respectively.
KRCA-0008 (0-1000 nM; 4 h) inhibits ALK-dependent signaling pathways more potently than crizotinib.
KRCA-0008 (0-1000 nM; 72 h) induces cell apoptosis.
KRCA-0008 (0-100 nM; 48 h) affects cell cycle.
Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
