Entacapone Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Entacapone was introduced in Finland, Germany and Sweden as an
adjunctive treatment with L-dopa in Parkinson’s disease. Entacapone is the
second drug in its class to reach the market; it can be obtained by
basecatalyzed condensation of the corresponding benzaldehyde with a
cyanoacetamide. Entacapone is a highly selective and orally-active catechol-0-
methyltransferase (COMT) inhibitor ; by inhibiting metabolism of L-dopa when
given as an adjuvant in patients with Parkinson’s disease, Entacapone markedly
prolongs the effects of L-dopa and improves its bioavailability. Results from
clinical studies showed that 200mglday Entacapone coadministered with L-dopa
lowered the dose of the latter required to reduce fluctuations in motor
performance.
Chemische Eigenschaften
Yellow Crystalline Solid
Verwenden
(E)-Isomer of Entacapone polymorphic form A. Peripherally acting inhibitor of catechol-O-methyl transferase (COMT), an enzyme involved in the metabolism of catecholamine neurotransmitters and related drugs. Antiparkinsonian
Definition
ChEBI: A monocarboxylic acid amide that is N,N-diethylprop-2-enamide in which the hydrogen at position 2 is substituted by a cyano group and the hydrogen at the 3E position is substituted by a 3,4-dihydroxy-5
nitrophenyl group.
Allgemeine Beschreibung
Entacapone, (E)-2-cyano-3-(3,4-dihydroxy-5-nitrophenyl)-N,N-diethyl-2-propenamide (Comtan),is a nitrocatechol that is practically insoluble in water (pK
a＝4.50). Entacapone is rapidly absorbed after oral administrationand does not cross the BBB. Entacapone does not distributewidely into tissues because of its high plasma proteinbinding and it is completely metabolized before excretion.The main metabolic pathway is by isomerization to the cisisomerfollowed by direct glucuronidation of the parent andthe cis-isomer. The glucuronide conjugates are inactive.Entacapone is eliminated in the feces (90%) and urine (10%).Entacapone is indicated as an adjunct to levodopa/carbidopato treat patients with idiopathic PD who experience the signsand symptoms of end-of-dose wearing off.
