Catalog Number: 5368
Chemical Name: 1,1'-(4,4',5,5'-Tetrachloro[1,3'-bi-1H-pyrrole]-2,2'-diyl)bis[1-2-hydroxyphenyl)methanone
Biological Activity
Mcl-1 inhibitor; disrupts Mcl-1-Bim interaction and induces Mcl-1 proteasomal degradation. Exhibits no effect on Bcl-XL-Bim interaction. Selectively induces apoptosis in Mcl-1-dependent K562 leukemia cells. Sensitizes K562 and Raji cells to ABT-737-induced apoptosis.

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?
