Catalog Number: 4703
Alternate Names: DZNep, NSC 617989
Chemical Name: (1S,2R,5R)-5-(4-Amino-1H-imidazo[4,5-c]pyridin-1-yl)-3-(hydroxymethyl)-3-cyclopentene-1,2-diol hydrochloride
Biological Activity
Histone methyltransferase inhibitor; decreases global histone methylation. Inhibits EZH2 histone methyltransferase and s-adenosylhomocysteine (SAH) hydrolase activity. Blocks trimethylation of lysine 27 on histone H3 and lysine 20 on histone H4 in vitro. Induces apoptosis in multiple cancer cell lines and has no apoptotic effect on normal cells. Enhances Oct4 expression in chemically induced pluripotent stem cells (CiPSCs).

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?
