The effects of a new agonist of histamine (HA) H3 receptors, Imetit (S-[2-(4-(imidazolyl)ethyl]isothiourea) were investigated in vitro and in vivo and compared to those of (R)-alpha-methylhistamine [(R)-alpha-MeHA], a prototypic drug. Imetit inhibited the binding of [3H](R-alpha-MeHA to rat brain membranes

Reuptake and clearance of released serotonin (5-HT) are critical in serotonergic neurotransmission. Serotonin transporter (SERT) is mainly responsible for clearing the extracellular 5-HT. Controlled trafficking, phosphorylation, and protein stability have been attributed to robust SERT activity. H3 histamine receptors (H3Rs)

Neurochemistry international, 101, 38-47 (2016-11-05)
The histamine H3 receptor (H3R) is abundantly expressed in the Central Nervous System where it regulates several functions pre and postsynaptically. H3Rs couple to Gαi/o proteins and trigger or modulate several intracellular signaling pathways, including the cAMP/PKA pathway and the
