Description

ALK-IN-26 is an ALK inhibitor with IC50 value of 7.0 μM for ALK tyrosine kinase. ALK-IN-26 has good pharmacokinetic properties and blood-brain barrier (BBB) permeability. ALK-IN-26 can induce apoptosis, autophagy and necrosis. ALK-IN-26 can be used in glioblastoma studies[1].

In Vitro

ALK-IN-26 (0.5-2 μM, 24 h) can inhibit the activity of ALK in GL216 cells[1].
ALK-IN-26 (0.5-2 μM, 24 h) can reduce the expression of mTOR protein in GL216 cells [1].
[1].
ALK-IN-26 (0.5-2 μM, 24 h) significantly decreases p-ERK1/2 protein level and enhances p-JNK protein level in GL261 and U87MG cells, while has little effect on p-AKT and p-STAT3 protein levels[1].
ALK-IN-26 (0.5μM-2.0 μM, 24h) can induce autophagy in GL261 cells[1].
ALK-IN-26 (0.5 μM-0.5 μM, 24-72 h) increases the protein levels of cleaved-PARP (c-PARP) and cleaved-caspase-3 (c-caspase 3) in GL261 cells[1].
ALK-IN-26 (0.5 μM-2μM, 24-72 h) induces apoptosis in GL261 cells[1].

Apoptosis Analysis[1]

Cell Line: GL261
Concentration: 0.5 μM, 1.0 μM, 2.0 μM
Incubation Time: 24 h, 48 h, 72 h
Result: Induced apoptosis of glioblastoma in a concentration- and time-dependent manner, and caused the cells (24.5%) entered the S phase but barely proceeded to the G2/M phase when treated with 1 μM for 72 h.

Cell Viability Assay[1]

Cell Line: GL216, U87MG, Hela
Concentration: 0.5 μM, 1.0 μM, 2.0 μM, 5 μM, 10 μM for GL216 and U87MG cells 5 μM, 10 μM, 20 μM, 40 μM, 80 μM, 160 μM for Hela cells
Incubation Time: 24 h, 48h, 72h
Result: Inhibited the activity of GL216 cells with the inhibition rate of cells at 80% when incubated with 2 μM for 72 h and inhibited U87MG cells viability with a dose- and time-dependent manner, while showed limited inhibition on Hela cells, even at 160 μM, the inhibition rate is less than 50%.
Can inhibit the activity of ALK tyrosine kinase with a dose-dependent manner.

Cell Autophagy Assay[1]

Cell Line: GL261
Concentration: 0.5 μM, 1.0 μM, 2.0 μM
Incubation Time: 24 h
Result: Induced autophagy death in glioblastoma cells.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
