Catalog Number: 4667
Chemical Name: 2-Bromo-4,5-dimethoxy-N-[3-[[(3R)-1-methyl-3-pyrrolidinyl]oxy]-4-(trifluoromethyl)phenyl]benzenesulfonamide
Biological Activity
High affinity, non-peptide antagonist of the urotensin-II (UT) receptor. Exhibits high affinity for mammalian UT receptors, including human, mouse and rat (Ki values are 9.3, 19.1 and 20.7 nM respectively, in HEK293 cells expressing recombinant UT receptors). Also inhibits binding of radiolabeled urotensin to endogenous human UT receptors (Ki = 5.4 nM in a whole-cell binding assay). Displays ≥100-fold selectivity for the human UT receptor over 86 different receptors, ion channels, enzymes, transporters and nuclear hormones.

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?
