Alternative Name: Indirubin-3'-monoxime

Chemical Name: 3-[1,3-Dihydro-3-(hydroxyimino)-2H-indol-2-ylidene]-1,3-dihydro-2H-indol-2-one

Biological Activity

Protein kinase inhibitor; inhibits cyclin-dependent kinases (IC50 = 0.18 - 3.33 μM) and GSK-3β (IC50 = 0.19 μM). Inhibits CDK5- and GSK-3β-mediated tau phosphorylation, a process over-active in Alzheimer disease states. Also inhibits AMPK, LCK and SGK. Induces cell cycle arrest and inhibits cell proliferation.

Technical Data

Soluble to 100 mM in DMSO and to 100 mM in ethanol
>99 %
Store at RT
