Catalog Number: 2156
Chemical Name: 2,5-Dihydroxy-3-undecyl-2,5-cyclohexadiene-1,4-dione
Biological Activity
Cell-permeable, non-peptide inhibitor of X-linked inhibitor of apoptosis (XIAP) (IC50 = 4.1 μM in competition binding assay with Smac peptide); binds to the BIR3 domain, preventing XIAP interaction with caspase-9 and Smac. Inhibits cell growth, induces apoptosis and activates caspase-9 in prostate cancer cells (IC50 4 - 6 μM), but has a weaker effect on normal prostate cells (IC50 = 19 - 20 μM). Overcomes the protective effect of XIAP on apoptosis in XIAP-transfected Jurkat cells. Anti-tumor, analgesic and anti-inflammatory 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?
