Galanin Receptor Ligand M35 is a high-affinity ligand and antagonist of galanin receptor (K_d=0.1 nM). Galanin Receptor Ligand M35 exerts a K_i values of 0.11 and 2.0 nM for human galanin receptor type 1 and 2, respectively^[1][2]. IC50 & Target: Kd: 0.1 nM (galanin receptor)^[1]
Ki: 0.11 nM (human galanin receptor type 1), 2.0 nM (human galanin receptor type 2)^[2] In Vitro: Galanin Receptor Ligand M35 has a dual effect on the galanin mediated inhibition of Forskolin stimulated cyclic AMP production in Rin m 5F cells. Co-applied with galanin (10 nM), Galanin Receptor Ligand M35 at low concentrations (1 nM) is able to reverse the inhibitory effect of galanin. But when present at higher concentrations (15 and 30 nM), Galanin Receptor Ligand M35 acts as a galanin receptor agonist, inhibiting the forskolin stimulated production of cAMP^[1]. In Vivo: Galanin Receptor Ligand M35 (6 nM/10 μL; i.c.v.) improves the ability of the male Sprague-Dnwley rats to acquire the swim maze task^[1].
