Tolvaptan (OPC-41061) is an orally bioavailable, selective, arginine vasopressin receptor 2 (V2, AVPR2) antagonist that can be used to treat hyponatremia.

Argipressin (Arg8-vasopressin) inhibits central corticotropin-releasing hormone. Argipressin acts as a repressor in the regulation of central CRH levels. 5A2-SC8 is an APC-dependent protein.

E-4177 is an angiotensin II type 1 receptor (AT1R) antagonist and can be used to study cardiovascular diseases.

Desmopressin acetate (16679-58-6 free base) (DDAVP) is the synthetic analog of the antidiuretic hormone arginine vasopressin. Vasopressin Receptor The antidiuretic properties of desmopressin have led to its use in polyuric conditions including primary nocturnal enuresis, nocturia, and diabetes insipidus. Desmopressin acetate (16679-58-6 free base) works by limiting the amount of water that is eliminated in the urine. Desmopressin acetate (16679-58-6 free base) binds to V2 receptors in renal collecting ducts, increasing water reabsorption. It also stimulates the release of von Willebrand factor from endothelial cells by acting on the V2 receptor.

Fuscoside (OPC-21268) is a non-peptide arginine vasopressin (AVP) receptor VI antagonist with an IC50 value of 0.4 μM[2].

Fedovapagon (VA106483) is a selective and potent agonist of the vasopressin V2 receptor (V2R) that inhibits the growth of intersegmental vessels in zebrafish. It can be used to study overactive bladder, nocturia, and painful bladder syndromes.

Felypressin (Octapressin) is a synthetic analog of LYPRESSIN with a PHENYLALANINE substitution at residue 2. Felypressin is a vasoconstrictor with reduced antidiuretic activity.

Felypressin acetate (PLV-2) is an agonist of vasopressin 1 and acts on all arginine vasopressin receptors 1AS. Felypressin acetate can be used in dental procedures.

Urotensin II is a peptide vasoconstrictor and agonist of the urotensin (UT) receptor (Ki= 2.06 nM for the human recombinant receptor expressed in HEK293 cells).1It stimulates intracellular calcium mobilization in HEK293 cells expressing human and rat UT (EC50s = 0.47 and 0.78 nM, respectively) but decreases intracellular calcium concentration in goby (G. mirabilis) enterocytes when used at a concentration of 500 nM.2Urotensin II (20 mU/ml) stimulates active sodium and chloride absorption across isolated goby posterior intestine in 5% seawater-adapted solution.3In vivo, urotensin II (1.5-150 nmol/kg) decreases diastolic blood pressure and increases heart rate in anesthetized rats.4It also reduces the pressor responses to sympathetic nerve stimulation, norepinephrine , and vasopressin in pithed rats when administered at a dose of 150 nmol/kg. 1.Ames, R.S., Sarau, H.M., Chambers, J.K., et al.Human urotensin-II is a potent vasoconstrictor and agonist for the orphan receptor GPR14Nature401(6750)282-286(1999) 2.Loretz, C.A., and Assad, J.A.Urotensin II lowers cytoplasmic free calcium concentration in goby enterocytes: Measurements using quin2Gen.

Mozavaptan (OPC-31260) is a competitive antagonist of vasopressin receptors, targeting both V1 and V2 receptors, with IC50 values of 1.2 μM and 14 nM, respectively.

Conivaptan hydrochloride (Vaprisol) is an orally active vasopressin V2 and V1A receptor antagonist, used in the therapy of hypervolemic hyponatremia and euvolemic.

D[LEU4,LYS8]-VP TFA is a selective agonist for the vasopressin V1b receptor, with Ki values of 0.16 nM for rat, 0.52 nM for human, and 1.38 nM for mouse V1b receptors. This compound exhibits limited antidiuretic, vasopressor, and oxytocic activities in vitro [1] [2].

d[Cha4]-AVP TFA is a potent and selective agonist for the vasopressin (AVP) V1b receptor, with a high affinity (K i of 1.2 nM). It shows greater selectivity for the V1b receptor over the V1a receptor, V2 receptor, and oxytocin receptors, demonstrating specificity in targeting the human V1b receptor [1] [2].
