Biochem/physiol Actions

OPC-21268 is one of 2 non-peptide V1a selective antagonists, along with SR-49059. Arginine vasopressin (AVP) is a hormone that plays an important part in circulatory and water homoeostasis and is important in renal hemodynamic alterations, water retention, and cardiac remodeling in congestive heart failure (CHF). There are three AVP receptor subtypes-V1a, V1b, and V2 - all belong to the large rhodopsin-like G-protein-coupled receptor family. V(1a) antagonists improve water balance and cardiac hypertrophy in CHF and might be beneficial for the treatment of water retention and cardiac remodeling in CHF.

Active transport of sodium ions across the isolated abdominal skin of the frog Rana temporaria after application of arginine-vasotocin (AVT) and 1-deamino-arginine-vasotocin (1dAVT) was studied by measurement of the short-circuit current (SCC). The maximal increase in the SCC values (26

Arginine vasopressin (AVP) might influence urinary concentration ability by altering the intrarenal distribution of glomerular filtration rate (GFR). To study this possibility we have measured the intracortical distribution of GFR following acute AVP-V1 receptor stimulation in anaesthetized female Sprague-Dawley (SPD)

The involvement of vasopressin (AVP) in several pathological states has been reported recently and the selective blockade of the different AVP receptors could offer new clinical perspectives. During the past few years, various selective, orally active AVP V1a (OPC-21268, SR49059

Amphibian skin has osmoregulatory functions, with Na(+) crossing from outside to inside. Na(+) transport can be measured as the short-circuit current (SCC). We investigated the short-term and long-term effects of arginine vasotocin (AVT) and mesotocin (MT) (which modulate Na(+) transport)
