Catalog Number: 4219
Alternate Names: AQ4N
Chemical Name: 1,4-Bis[[2-(dimethyloxidoamino)ethyl]amino]-5,8-dihydroxy-9,10-anthracenedione dihydrochloride
Biological Activity
Bioreductive prodrug; activated by hypoxia to yield the topoisomerase II inhibitor AQ4. Displays little to no cytotoxic activity against 60 tumor cell lines tested under oxic conditions (IC50 >100 μM). Exhibits anti-tumor efficacy in vivo when combined with oxic cell cytotoxins; enhances the anti-tumor effect of cyclophosphamide (Cat. No. 4091) in a mouse tumor model.

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?
