Application

Metergoline has been used as a serotonin receptor antagonist:

  • to study its effects on astrocyte calcium signals evoked by whisker stimulation
  • to study its effects on lipopolysaccharide-induced anorexia in rats
  • to evaluate the non-specific binding by 5-HT1A receptor binding assays

Biochem/physiol Actions

Metergoline is an ergot alkaloid and a selective serotonin antagonist which blocks the 5-HT2A and 5-HT2C receptors with higher affinity. It possesses antifungal activity against infection caused by Candida krusei. Metergoline exhibits a therapeutic effect against premenstrual dysphoric disorder. It also exhibits antipyretic and analgesic activities.

N-phenylpiperazine analogs can bind selectively to the D3 versus the D2 dopamine receptor subtype despite the fact that these two D2-like dopamine receptor subtypes exhibit substantial amino acid sequence homology. The binding for a number of these receptor subtype selective

Timing of the circadian clock of the suprachiasmatic nucleus (SCN) is regulated by photic and non-photic inputs. Of these, neuropeptide Y (NPY) signaling from the intergeniculate leaflet (IGL) to the SCN plays a prominent role. Although NPY is critical to
