개요Domperidone maleate is a specific blocker of dopamine receptors. It speeds gastrointestinal peristalsis, causes prolactin release, and is used as antiemetic and tool in the study of dopaminergic mechanisms.
용도Domperidone maleate (CAS# 99497-03-7); a form of Domperidone (D531100), a novel peripheral dopamine receptor antagonist that does not cross the blood-brain barrier; anti-emetic. Domperidone(Motilium) is a dopamine blocker and an antidopaminergic reagent.
Domperidone was synthesized at Janssen Pharmaceutica in 1974 following their research on antipsychotic drugs. The present invention relates to synthesis of domperidone maleate. O-diaminobenzene is first cyclized and halogenated to form the first benzimidazolone intermediate; 1-carbethoxy-4-amino piperidine is halogenated, reduced, cyclized and hydrolyzed to form the second benzimidazolone intermediate; the two benzimidazolone intermediates are reacted to produce domperidone; and domperidone is finally reacted with maleic aicd to produce domperidone maleate.https://patents.google.com/patent/CN1810805A/en
