Catalog Number: 1813
Alternate Names: 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.

Molarity Calculator
Calculate the mass, volume or concentration required for a solution

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)
An example of a molarity calculation using the molarity calculator:
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
