Catalog Number: 2310
Alternate Names: Relcovaptan
Chemical Name: (2S)-1-[[(2R,3S)-5-Chloro-3-(2-chlorophenyl)-1-[(3,4-dimethoxyphenyl)sulfonyl]-2,3-dihydro-3-hydroxy-1H-indol-2-yl]carbonyl]-2-pyrrolidinecarboxamide
Biological Activity
Potent and selective non-peptide vasopressin V1A receptor antagonist; devoid of agonist activity. Displays high affinity and efficacy at both rat (Ki = 1.6 nM) and human (Ki = 1.1 - 6.3 nM) V1A receptors. Potently antagonizes arginine vasopressin-induced effects in vitro (IC50 = 3.7 nM for inhibition of human platelet aggregation) and is orally active in vivo.

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?
