Catalog Number: 2002
Alternate Names: Bisindolylmaleimide IX
Chemical Name: 3-[3-[2,5-Dihydro-4-(1-methyl-1H-indol-3-yl)-2,5-dioxo-1H-pyrrol-3-yl]-1H-indol-1-yl]propyl carbamimidothioic acid ester mesylate
Biological Activity
Protein kinase C inhibitor, with activity at other protein kinases (IC50 values are 33, 3, 8, 15 and 38 nM for PKCα, MAPKAP-K1b, MSK1, GSK3β and S6K1 respectively). Activates JNK and glycogen synthase, and inhibits MAPK and ERK2, in rat adipocytes and L6 myotubes. Also inhibits voltage-dependent Na+ channels in the micromolar range.

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?
