M40 is a chimeric galanin-derived peptide and galanin-1 (GAL1) receptor antagonist and GAL2 receptor agonist (Kis = 2.4 and 4.07 nM, respectively).[1],[2] It is selective for the GAL1 and GAL2 receptors over the GAL3 receptor (Ki = 288 nM).[1] M40 induces inositol phosphate accumulation in CHO cells expressing the human GAL2 receptor (EC50 = 16.2 nM) and inhibits forskolin-induced cAMP accumulation in RIN-m5F pancreatic β-cells when used at concentrations of 10 or 100 nM.[1],[2] In vivo, M40 (9.36 nmol/animal, i.c.v.) reverses galanin-induced inhibition of scopolamine-induced hippocampal acetylcholine (ACh) release in conscious rats.[2] M40 reduces galanin-induced increases in food intake in rats. It improves cardiac function and decreases cardiac fibrosis in a rat model of heart failure induced by sustained coronary artery ligation when administered at a dose of 30 nmol/kg.[3] M40 (20 µg/animal) increases the intromission frequency and ejaculation latency in sexually sluggish male mice.[4]
