Catalog Number: 3571
Chemical Name: 2-Bromo-N-[4-chloro-3-[[(3R)-1-methyl-3-pyrrolidinyl]oxy]phenyl]-4,5-dimethoxybenzenesulfonamide
Biological Activity
Selective urotensin-II (UT) receptor antagonist (Ki values are 61, 17, 30, 65 and 56 nM at human, monkey, cat, rat and mouse receptors respectively). Inhibits U-II-induced intracellular Ca2+ mobilization (IC50 = 180 nM) and antagonizes the contractile action of U-II in isolated mammalian arteries and aortae (EC50 = 50 - 189 nM).

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?
