• R-Sätze Betriebsanweisung:

  R22:Gesundheitsschädlich beim Verschlucken.

• Originator

  Moban,Endo,US,1974

• Verwenden

  Antipsychotic.

• Verwenden

  Molindone is a more active antipsychotic than chloropromzine. Its sedative effect is less expressed. Side effects are also expressed less than with powerful neuroleptics. It facilitates the reduction of spontaneous movements and aggressiveness, and is used for treatment of psychotic disturbances, particularly in cases of chronic and severe schizophrenia.

• Definition

  ChEBI: Molindone is a member of indoles.

• Manufacturing Process

  Diethyl ketone may be reacted with methyl nitrite and that product in turn reacted with cyclohexan-1,3-dione to give 3-ethyl-4,5,6,7-tetrahydro-2- methyl-4-oxoindole.
  3-ethyl-4,5,6,7-tetrahydro-2-methyl-4-oxoindole 14.1 g (0.08 mol), 14.8 g morpholine hydrochloride (0.12 mol), and 3.6 g paraformaldehyde (0.12 mol) were refluxed in 200 ml ethanol for 40 hours. The solution was evaporated to dryness in vacuo on a steam bath and the residue digested with a mixture of 150 ml water and 10 ml 2N HCl. An insoluble residue of unreacted starting material was filtered off. To the acid solution, ammonia water was added dropwise with stirring and the amine crystallized out. It was purified by dissolving in 1N HCl and addition of ammonia, then by 2 crystallizations from benzene followed by 2 crystallizations from isopropanol, to yield 3-ethyl- 4,5,6,7-tetrahydro-2-methyl-4-oxoindole, melting point 180°C to 181°C.

• Therapeutic Function

  Antipsychotic

• Nebenwirkungen

  Molindone hydrochloride, a tetrahydro-indolone derivative, is a neuroleptic agent that is structurally unrelated to any of the other marketed neuroleptics. Molindone is less potent than haloperidol at blocking D2 receptors; however, it nonetheless can produce extrapyramidal side effects.

• Synthese

  Molindone, 3-ethyl-6,7-dihydro-2-methyl-5-(morpholinomethyl)indol-4(5H)- one (6.4.3), is synthesized by the nitrozation of diethylketone using nitric acid or methylnitrite into nitrozodiethylketone (6.4.1). Reduction of this product with zinc in acetic acid into 2-aminodiethylketone in the presence of cyclohexandion-1,3 gives 3-ethyl-2-methyl- 4,5,6,7-tetrahydroindol-4-one (6.4.2). Aminomethylation of this product using morpholine and formaldehyde gives molindone (6.4.3) [51¨C52].

  

• Stoffwechsel

  Metabolism studies in humans show molindone to be rapidly absorbed and metabolized when given orally. There are 36 recognized metabolites, with less than 2 to 3% unmetabolized molindone being excreted in urine and feces. Clinical studies show that the antipsychotic effects of molindone last more than 24 hours, suggesting that one or more metabolites may contribute to its activity in vivo (62).
