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.
