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.

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.

Cocaine- and amphetamine-regulated transcript (CART) with potent appetite-suppressing activity. Satiety factor; inhibits normal and starvation-induced feeding. Closely related to the actions of leptin and neuropeptide Y; blocks the neuropeptide Y-induced feeding response.
