(d(CH2)51,Tyr(Me)2,Arg8)-Vasopressin
Purity: ≥95%
Biological Activity
(d(CH2)51,Tyr(Me)2,Arg8)-Vasopressin is a selective vasopressin V1A receptor antagonist. Inhibits vasopressin and oxytocin-induced increases in intracellular calcium concentrations in vitro (IC50 values are 5 and 30 nM respectively). Exhibits potent and prolonged antivasopressor activity and induces anxiolytic-like effects in the dorsal, but not ventral, hippocampus in vivo.Technical Data
(Modifications: X = Pmp, Tyr-2 = Tyr(Me), Disulfide bridge: 1-6, Gly-9 = C-terminal amide)
