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.

5-HT₄ receptor (5-HT₄R) activation induces procognitive effects. This might be related to stimulation of hippocampal acetylcholine release, which has been shown for 5-HT₄R agonists in in-vivo models. We investigated the influence of the 5-HT₄R agonists, prucalopride and BIMU-8, on acetylcholine

Serotonin (5-HT) is involved in a large variety of physiological functions and it appears now that it could play a role in cognitive processes through the activation of 5-HT4 receptors. The present study was conducted to determine the effect of

Recently, a 5-hydroxytryptamine (5-HT) receptor has been described, whose pharmacology was distinct from that of the already known serotonergic receptors, so that it has been called 5-HT4. Because the lack of a high affinity radioligand, the identification of this receptor

The effect of the serotonergic 5-HT4 receptor agonists BIMU 1 and BIMU 8 on in vivo acetylcholine (ACh) release in brain hemispheric regions of freely moving rats was investigated using the microdialysis technique. Both agonists, applied intracerebroventricularly, facilitated the release

The effects of the administration of different 5-HT4 receptor antagonists (SDZ 205557, GR 125487) and 5-HT4 receptor agonists (BIMU 1, BIMU 8) on memory processes were evaluated in the mouse passive avoidance test. The administration of SDZ 205557 (10 mg
