Catalog Number: 4330
Chemical Name: 3-Amino-5-[[2-[(2-methoxyethyl)amino]-6-[4-(trifluoromethyl)phenyl]-4-pyrimidinyl]oxy]-2(1H)-quinoxalinone
Biological Activity
Potent and selective TRPV1 antagonist. Blocks Ca2+ uptake by CHO cells expressing TRPV1 receptors (IC50 values are 0.6 and 0.8 nM for capsaicin (Cat. No. 0462) and acid-induced Ca2+ uptake, respectively). Exhibits >4000-fold selectivity for TRPV1 over other TRP channels. Blocks capsaicin-induced flinch response and causes hyperthermia in rats. Orally available and non-CNS penetrant.

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?
