GR113808 is an antagonist of the serotonin (5-HT) receptor subtype 5-HT4.{42967} It binds to 5-HT4 receptors with an IC50 value of 0.4 nM in COS-7 cells expressing the human recombinant receptor and in guinea pig striatal membranes (IC50 = 0.5 nM).{42968} GR113808 is selective for 5-HT4 receptors over 5-HT1 receptors (Kis = >10 µM in dog saphenous vein and porcine vena cava), as well as 5-HT2 and 5-HT3 receptors (Kis = >10 and 1 ?M in rabbit thoracic aorta and rat cerebral cortex, respectively).{42967} It is also selective for 5-HT4 over adenosine, adrenergic, dopamine, GABA, muscarinic, nicotinic, histamine, and NMDA receptors (Kis = >10 ?M for all). GR113808 inhibits relaxation induced by 5-HT (Item No. 14332) in rat thoracic esophagus precontracted by carbachol (carbamoylcholine; Item No. 14486; pA2 = 9.3). In vivo, GR113808 inhibits 5-methoxytryptamine-induced tachycardia in anaesthetized piglets.
