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

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

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)

In drug discovery, assays with proximal readout are of great importance to study target-specific effects of potential drug candidates. In the field of G protein-coupled receptors (GPCRs), the determination of GPCR-G protein interactions and G protein activation by means of
