Catalog Number: 3367
Chemical Name: (-)-1,1',6,6',7,7'-Hexahydroxy-3,3'-dimethyl-5,5'-bis(1-methylethyl)-[2,2'-binaphthalene]-8,8'-dicarboxaldehyde
Biological Activity
R-(-)-enantiomer of gossypol (Cat. No. 1964). Mimics the BH3 domains of Bcl-2, Bcl-XL and Mcl-1. Disrupts heterodimerization of Bcl-2 with proapoptotic family members. Induces apoptosis in vitro through activation of caspase-9; cytotoxic to multiple myeloma and drug-resistant cell lines. Delays onset of androgen-independent growth of VCaP prostate cancer xenografts 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?
