Biological Activity

(d(CH₂)₅¹,Tyr(Me)²,Arg⁸)-Vasopressin is a selective vasopressin V_1A 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.
