Biochem/physiol Actions SR 49059 is a potent and selective Arginine Vasopressin (AVP) V1a-receptor antagonist. 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. SR 49059 has also shown initial positive results in the treatment of Raynaud′s disease, dysmenorrhoea, and tocolysis. |
