Neuropeptide Y (13-36), amide, human is a neuropeptide Y receptor agonist. IC50 & Target: Neuropeptide Y receptor^[1] In Vivo: Intraventricular injections of the Y2 neuropeptide Y receptor agonist porcine Neuropeptide Y (13-36) (25-3000 pM) produces a dose-dependent increase (up to 14%; ED₅₀=0.3 nM for overall effects and 0.97 nM for the peak effects) in mean arterial blood pressure in the awake, unrestrains male rat without affecting heart rate. Central administration of porcine Neuropeptide Y (13-36) produces marked vasodepressor and bradycardic actions in the anaesthetized α-chloralose and in the awake unrestrained male rat^[1].
