Biochem/physiol Actions

BIMU8 hydrate is a potent 5-HT4 serotonin receptor agonist. Serotonin (5-HT) is a major neurotransmitter that acts through a family of GPCRs and one ion channel. 5-HT4 receptor is GPCR expressed in many tissues, including brain, and modulates dopamine secretion, learning, and memory. BIMU8 is a full agonist at 5-HT4, but it binds differently than the endogenous ligand, 5-HT, shown through site-directed mutagenesis studies. It depolarizes neurons and was used to localize 5-HT4 to somatic but not dendritic regions of CA1 pyramidal neurons.

We have previously shown that serotonin (5-hydroxytryptamine, 5-HT) stimulate corticosterone and aldosterone secretion from perifused frog adrenal gland in vitro through activation of 5-HT4 receptors. In the present study, we have used this model to investigate the effect of newly

Three chemical classes of serotonin 5-HT4 receptor agonists have been identified so far: 5-substituted indoles (e.g. 5-HT), benzamides (e.g. renzapride) and benzimidazolones (e.g. BIMU 8). In a search for 5-HT4 receptor antagonists, we have discovered that the benzimidazolone derivative DAU

Recent experimental evidence indicates that central 5-HT4 receptors which are positively coupled to adenylate cyclase, are stimulated by a family of 2-methoxy-4-amino-5-chloro substituted benzamide derivatives. These compounds are also potent stimulants of the gastro-intestinal motility. In this study the ability

Three benzimidazolone derivatives have been evaluated in the tunica muscularis mucosae preparation of the rat oesophagus for activity at the 5-HT4 receptor. BIMU 1 (endo-N-(8-methyl-8-azabicyclo-[3.2.1]oct-3-yl)-2,3-dihydro-3-ethyl-2-ox o- 1H-benzimidazole-1-carboxamide HCl) and BIMU 8 (endo-N-(8-methyl-8-azabicyclo[3.2.1]oct-3-yl)-2,3-dihydro-(1-methyl)eth yl- 2-oxo-1H-benzimidazole-1-carboxamide HCl) acted as potent but partial

In vitro studies have demonstrated a 5-HT4 receptor-mediated relaxation of the pre-contracted rat esophagus. However, it is unclear whether 5-HT4 receptor agonists affect resting esophageal tone in vivo. The activity of 5-HT and several well-established 5-HT4 receptor agonists (tegaserod, BIMU-8
