Galantide is a galanin antagonist consisting of aa 1-13 of galanin and the C-terminal fragment of bradykinin. Galantide reversibly blocks the neuronal activities of galanin. Galanin has different activities such as contraction of smooth muscle of the gastrointestinal and genito-urinary tract, regulation of growth hormone and insulin release, and control of adrenal secretion.H-Gly-Trp-Thr-Leu-Asn-Ser-Ala-Gly-Tyr-Leu-Leu-Gly-Pro-Gln-Gln-Phe-Phe-Gly-Leu-Met-NH2 or H-GWTLNSAGYLLGPQQFFGLM-NH2
