Curator's Comment: The description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/15823830 | https://www.ncbi.nlm.nih.gov/pubmed/14678081 | https://www.ncbi.nlm.nih.gov/pubmed/11035135

Relcovaptan is a potent, orally active nonpeptide vasopressin V1a antagonist that was undergoing clinical development with Sanofi-Synthélabo (formerly Sanofi) in France. SR49059 is specifically and selectively antagonizes the effect of vasopressin on the V1a receptor in animals’ and in humans. The drug has been shown to have an excellent safety profile in single and repeated dose toxicological studies in animals. In the human uterus in vitro, SR49059 caused a dose-dependent inhibition of vasopressin V1a receptor-mediated activity of myometrial strips and isolated uterine arteries. In vivo in nonpregnant women, an inhibition of vasopressin-induced uterine activity has been observed.

MDCK II cells were seeded on 12 multiwell filters (Costar) at a density of 150,000 cells/cm2 and grown for 3 days. Cells were subsequently treated with the antagonists for 16 h, followed by three washes with ice-cold phosphate-buffered saline containing 1 mM MgCl2 and 0.1 mM CaCl2 (PBS-CM). The cells were then incubated for 1 h on ice with [3H]AVP (PerkinElmer Life Sciences, Boston, MA) and the antagonist (Relcovaptan) diluted in PBS-CM. Cells were washed three times with ice-cold PBS-CM, followed by excision of the filters and counting of the radioactivity
