Cabergoline Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Cabergoline is a potent, selective, and long-lasting dopamine D
2 receptor agonist
launched in 1993 in Belgium as a prolactin inhibitor. A single 1 mg dose of cabergoline
effectively prevents puerperal lactation for up to 14 days, remarkably superior to other drugs
that require a daily regimen. It has a low rate of rebound breast activity and good tolerability.
Cabergoline is also in clinical trials for Parkinson's disease, breast cancer, and
hyperprolactinaemia.
Chemische Eigenschaften
White Crystalline Solid
Verwenden
Cabergoline is an ergot derivative and a dopamine D2-receptor agonist (1,2,3). It inhibits the secretion of prolactin and growth hormone.
Definition
ChEBI: An N-acylurea that is (8R)-ergoline-8-carboxamide in which the hydrogen attached to the piperidine nitrogen (position 6) is substituted by an allyl group and the hydrogens attached to the carboxamide nitrogen are substit
ted by a 3-(dimethylamino)propyl group and an N-ethylcarbamoyl group. A dopamine D2 receptor agonist, cabergoline is used in the management of Parkinson's disease and of disorders associated with hyperprolactinaemia.
Allgemeine Beschreibung
Cabergoline, (6aR,9R,10aR)-7-allyl-N-(3-(dimethylamino)propyl)-N-(ethylcarbamoyl)-4,6,6a,7,8,9,10,10a-octahydroindolo[4,3-fg]quinoline-9-carboxamide (Dostinex), is a white powder soluble inalcohol, chloroform, and N,N-dimethylformamide; slightlysoluble in acidic solutions and in n-hexane; and insoluble inwater. Following oral administration, peak plasma concentrationsare reached within 2 to 3 hours. Cabergoline ismoderately bound to plasma proteins in a concentrationindependentmanner. The absolute bioavailability of cabergolineis unknown. Cabergoline is extensively metabolizedby the liver, predominantly via hydrolysis of the acylureabond of the urea moiety. CYP450 metabolism appears to beminimal. The major metabolites identified thus far do not contribute to the therapeutic effect of cabergoline. Lessthan 4% is excreted unchanged in the urine. Fecal excretionrepresents the main route of cabergoline elimination. Thereare no reports of interactions of cabergoline with other antiparkinsonianagents. Clarithromycin may elevate theplasma concentration of cabergoline by the inhibition ofboth CYP3A4 and P-glycoprotein.Cabergoline is a potentD
2 receptor agonist and is indicated for the treatment ofhyperprolactinemic disorders, either idiopathic or causedby pituitary adenomas.
Biologische Aktivität
Selective D 2 -like dopamine receptor agonist (K i values are 0.7, 1.5, 9.0 and 165 nM for D 2 , D 3 , D 4 and D 5 receptors respectively) that also displays high affinity for several serotonin receptor subtypes (K i = 1.2-20.0 nM for 5-HT 1A , 5-HT 1D , 5-HT 2A and 5-HT 2B ). Inhibits secretion of prolactin and growth hormone and reverses levodopa-induced dyskinesias in Parkinsonian monkeys.
