Selective galanin GAL1 receptor agonist (Ki values are 0.23 and 5.71 nM for GAL1 and GAL2 receptors respectively). Enhances food consumption in rats following i.c.v. administration and reduces CAP-induced inflammatory pain.

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.

Selective galanin GAL2 receptor antagonist (Ki values are 13.1 and 420 nM for GAL2 and GAL1 receptors respectively). Blocks the pro-nociceptive effect of GAL2 receptor agonists.
