| Description |
ALK-IN-22 (compound I-24) is a potent ALK inhibitor with IC50 values of 2.3, 3.7 and 2.9 nM for ALK, ALKL1196M and ALKG1202R, respectively. ALK-IN-22 down-regulated the phosphorylation of ALK and its downstream proteins. ALK-IN-22 induces apoptosis. ALK-IN-22 can be used for tumor research[1].

ALK-IN-22 (compound I-24) (72 hours) has anti-proliferative activities against ALK-positive karpas299, H2228 and H3122 cell lines with IC50 values of 11, 37 and 27 nM, respectively[1]. ALK-IN-22 (compound I-24) (0-100 nM; 24 hours; H2228 cells) has inhibitory effect on ALK and downstream signaling AKT and ERK[1]. ALK-IN-22 (compound I-24) (0-100 nM; 48 hours; H2228 cells) can induce apoptosis and achieve cell cycle arrest in G1 phase[1]. Western Blot Analysis[1] Cell Line: H2228 cells Concentration: 0, 25, 50 and 100 nM Incubation Time: 24 hours Result: Downregulated the phosphorylation level of ALK and blocked the expressions of ALK downstream key signaling AKT, ERK along with their activated forms in a dose-dependent fashion. Apoptosis Analysis[1] Cell Line: H2228 cells Concentration: 0, 25, 50 and 100 nM Incubation Time: 48 hours Result: The apoptotic rates were 14.23%, 23.94% and 31.70% at concentrations of 25 nM, 50 nM and 100 nM, respectively. Cell Cycle Analysis[1] Cell Line: H2228 cells Concentration: 0, 25, 50 and 100 nM Incubation Time: 48 hours Result: The percentage of cells in the G1 phase increased from 49.72% to 58.51% in a dose-dependent fashion.
