A galanin receptor agonist
Galnon is a galanin (GAL) receptor agonist (KD = 2.9 µM in Bowes cells expressing GAL1 receptors).1 It inhibits forskolin-induced adenylate cyclase activity in rat hippocampal membranes (EC50 = 10 µM). Galnon (2 mg/kg) reduces the maximal seizure score and increases the latency to first seizure in a mouse model of seizure induced by pentylenetetrazole . It reduces cocaine-induced motor activity and frontal cortex, but not nucleus accumbens, dopamine overflow, as well as blocks cocaine-primed reinstatement of cocaine-seeking behavior in rats.2 Galnon (1.5-5 mg/kg) reduces food intake in rats and mice.3
