Description

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.
