Catalog Number: 2287
Alternate Names: Staurosporinone
Chemical Name: 6,7,12,13-Tetrahydro-5H-indolo[2,3-a]pyrrolo[3,4-c]carbazol-5-one
Biological Activity
Inhibitor of protein kinase C (IC50 = 2.45 μM) that displays ~ 10-fold selectivity over protein kinase A (IC50 = 25.7 μM). Also inhibits β-lactamase, malate dehydrogenase and chymotrypsin (IC50 values are 8, 8 and 10 μM respectively). Exhibits antiviral activity against GCV-sensitive and -resistant strains of human cytomegalovirus (HCMV) (IC50 values range from 0.13 - 0.32 μM). Shows no activity against herpes simplex virus (HSV).

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?
