2-(3-Trifluoromethylphenyl)glycine hydrochloride is a precursor of substituted 2-acetamido-5-aryl-l, 2,4-triazolones. Substituted 2-acetamido-5-aryl-l, 2,4-triazolones are dual V1a/V2 receptor antagonists and can be used in cardiovascular disease research[1].
L-371,257 is an orally bioavailable, selective and competitive antagonist of oxytocin receptor (pA2=8.4) with high affinity at both the oxytocin receptor (Ki=19 nM) and vasopressin V1a receptor (Ki=3.7 nM)[1][2].
Tolvaptan is a selective, competitive arginine vasopressin receptor 2 antagonist with an IC50 of 1.28μM for the inhibition of AVP-induced platelet aggregation.IC50 value: 1.28 uM (inhibition of AVP-induced platelet aggregation)Target: vasopressin receptor 2Tolvaptan (OPC-41061) is a selective, competitive arginine vasopressin receptor 2 antagonist with an IC50 of 1.28μM for the inhibition of AVP-induced platelet aggregation. Tolvaptan (OPC-41061) is used to treat hyponatremia (low blood sodium levels) associated with congestive heart failure, cirrhosis, and the syndrome of inappropriate antidiuretic hormone (SIADH). Tolvaptan (OPC-41061) is also in fast-track clinical trials for polycystic kidney disease. Treatment with t tolvaptan (OPC-41061) causes rapid and sustained body weight reductions concurrent with increases in urine output, improves and/or normalizes serum sodium in hyponatremic patients, reduces signs and symptoms of congestion and increases thirst. However, tolvaptan (OPC-41061) has not been shown to decrease heart failure re-hospitalization or mortality. As an adjunct to standard therapy, tolvaptan (OPC-41061) is unique in that it is virtually the only novel agent tested in patients hospitalized for acute heart failure syndrome (AHFS) to reach its primary end point for short-term efficacy without causing deleterious side effects.
d[Cha4]-AVP is a potent and selective human vasopressin V1B receptor agonist (Ki values are 1.2, 151, 240 and 750 nM for V1B, V1A, Oxytocin and V2 receptors respectively). d[Cha4]-AVP stimulates ACTH and corticosterone secretion and exhibits negligible vasopressor activity in vivo.
(D-Arg8)-Inotocin is a potent, selective and competitive antagonist of vasopressin receptor (V1aR), with a Ki of 1.3 nM. (D-Arg8)-Inotocin shows more than 3000-fold selectivity for the human V1aR over the other three subtypes, OTR, V1bR and V2R[1].
Desamino(D-3-(3′-pyridyl)-Ala2,Arg8)-Vasopressin, a synthetic analog of vasopressin (AVP), is a weak agonist at antidiuretic receptor. However, Desamino(D-3-(3′-pyridyl)-Ala2,Arg8)-Vasopressin is a potent agonist at pituitary corticotrope receptor[1].
Desmopressin(DDAVP) acetate is the synthetic analogue of the antidiuretic hormone arginine vasopressin. IC50 Value:Target: Vasopressin ReceptorThe antidiuretic properties of desmopressin have led to its use in polyuric conditions including primary nocturnal enuresis, nocturia, and diabetes insipidus. Desmopressin works by limiting the amount of water that is eliminated in the urine. Desmopressin binds to V2 receptors in renal collecting ducts, increasing water reabsorption. It also stimulates release of von Willebrand factor from endothelial cells by acting on the V2 receptor.
Dp[Tyr(methyl)2,Arg8]-Vasopressin is a non-selective peptide arginine vasopressin Vlb receptor antagonist[1].
Nelivaptan (SSR-149415) is a selective and orally active vasopressin V1b Receptor antagonist (Ki: 3.7 and 1.3 nM for native and recombinant rat V1b receptors, respectively). Nelivaptan inhibits arginine vasopressin (AVP)-induced Ca2+ increase and corticotropin secretion. Nelivaptan can be used for research of stress and anxiety[1].
Terlipressin is a potent vasoconstrictor that acts via V1 receptors on arteriolar smooth muscle cells. Terlipressin can result in splanchnic vasoconstriction augmenting systemic arterial blood pressure with beneficial circulatory and renal effects that would be expected to also ameliorate the key pathophysiological changes responsible for the development of refractory ascites
