Potent galanin receptor 2/3 (GAL2/GAL3) agonist (EC50 values are 45.7 and 112.2 nM, respectively). Exhibits no significant activity at galanin receptor 1. Endogenous satiety-inducing peptide; inhibits long chain fatty acid uptake by adipocytes and decreases food consumption in diet-induced obese mice and rats. Attenuates LH secretion in goldfish. Exhibits anxiolytic effects in vivo.

Galanin (1-30), human is a 30-amino acid neuropeptide, and acts as an agonist of GalR1 and GalR2 receptors, with Kis of both 1 nM. Endogenous peptide with multiple endocrine, metabolic and behavioral effects. Has been shown to have an action on intestinal smooth muscle, insulin and somatostatin release, and synaptic neurotransmission.

Potent endogenous neuropeptide S receptor (NPSR) agonist (EC50 = 3 nM). Induces mobilization of intracellular Ca2+. Increases locomotor activity and wakefulness in mice. Also reduces anxiety-like behavior in mice.
