galantide

Galantide is a reversible and non-specific antagonist of galanin receptor.

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

Galantide TFA, a reversible and non-specific antagonist of the galanin (GAL) receptor, demonstrates dose-dependent inhibition of galanin-induced K+ conductance, exhibiting an IC50 value of 4 nM. It is utilized in neurological disease and hormone metabolism research [1] [2].
