Application

FAUC 213 has been used as a selective dopamine receptor D4-R antagonist:
  • to test its effect on the expression of luteinizing hormone in eel pituitary primary cell culture
  • to test its effect on bupropion induced hypophagia and locomotion in rats
  • to test its modulatory effects on rat basolateral amygdala in the presence of dopamine

Biochem/physiol Actions

FAUC 213 displays antipsychotic properties and may be of use in studies related to behavioral neurobiology and neurochemistry.
Highly selective D4 dopamine receptor full antagonist

Structure dependent efficacy studies in the field of selective D4 ligands led to the 2-aminomethyl substituted azaindole 2 (FAUC 213) that displayed strong D4 binding, high subtype selectivity, and complete antagonist properties in ligand-induced mitogenesis experiments. According to our schematic
Blocking alpha2A adrenoceptors, but not dopamine receptors, augments bupropion-induced hypophagia in rats.

The amygdala receives dopaminergic innervation, and dopamine (DA) enhances various activities in cognitive and emotional behaviors. Periodic bursts of spontaneous inhibitory postsynaptic currents (IPSCs) with a low (<1 Hz) inter-event frequency have been observed in projection neurons of the basolateral

2-[4-(4-Chlorophenyl)piperazin-1-ylmethyl]pyrazolo[1,5-a]pyridine (FAUC 213) is a highly selective antagonist at the dopamine D(4) receptor subtype. It was designed as a derivative of two partial antagonists and has been proven to be a complete antagonist in mitogenesis assay. In the present study

In various vertebrate species, dopamine (DA) exerts an inhibitory action on reproduction. In the European eel, DA plays a pivotal role in the inhibitory control of gonadotroph function and the blockade of puberty. In vivo studies have suggested that this
