Catalog Number: 2637
Alternate Names: Aspergillin
Chemical Name: (3R,5aS,6S,10aR)-2,3,5a,6-Tetrahydro-6-hydroxy-3-(hydroxymethyl)-2-methyl-10H-3,10a-epidithiopyrazino[1,2-a]indole-1,4-dione
Biological Activity
Immunosuppressive agent; blocks phagocytosis, cytokine production and proliferation of T and B cells. Non-competitively inhibits chymotrypsin-like activity of 20S proteasome; prevents degradation of IκBα, an endogenous blocker of NF-κB. Also inhibits farnesyltransferase and geranylgeranyltransferase I (IC50 values are 80 and 17 μM respectively) and displays antitumor activity against breast cancer in vivo.

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?
