Catalog Number: 4531
Chemical Name: 2-(Acetyloxy)benzoic acid 4-[(nitrooxy)methyl]phenyl ester
Biological Activity
NO-donating aspirin; anti-inflammatory. Blocks inflammatory mediator production in isolated human monocytes (IC50 values are 0.07, 0.13, 0.15 and 0.18 μM for IL-1β, PGE2, IL-10 and TNF-α respectively). Decreases COX-2 expression (IC50 = 0.13 μM); disrupts proteasome-mediated degradation of iκB-α. Antiproliferative in HCT116 colon cancer cells; sensitizes drug-resistant ovarian tumor cells to cisplatin (Cat. No. 2251).

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?
