Hazard Information

Uses

Galantide, a non-specific galanin receptor antagonist, is a peptide consisting of fragments of galanin and substance P. Galantide recognizes two classes of galanin binding sites (KD<0.1 nM and ~6 nM) in the rat hypothalamus. Galantide dose dependently (IC50=1.0 nM) antagonizes the galanin-mediated inhibition of the glucose-induced insulin secretion from mouse pancreatic islets. Galantide appears to bind to a single population of SP receptors (KD~40 nM)[1][2][3].

in vivo

Intracerebroventricular injection of galanin (5 micrograms/rat) inhibited sexual behavior in experienced male rats--without producing any other locomotor or behavioral deficit-, injection of the galanin antagonist, galantide, by the same route (1 or 2 micrograms/rat) stimulated sexual behavior (improving arousal, motivation and performance indexes) and antagonized the effect of galanin^[2]. Galantide ameliorates mild acute pancreatitis (AP). Galantide significantly reduces AP-induced hyperenzymemia by 41–49%^[3]. Galantide has been found to improve social memory in 'socialrecognition' test when i.c.v. administered at doses varying from 6-6000 nM^[4].
