Memantine kann zukünftig noch umweltschonender und kostengünstiger dank Erfindung der Justus-Liebig-Universität Gießen hergestellt werden

TransMIT vermittelt neuartiges Verfahren zur Herstellung von Alzheimer-Wirkstoff

(PresseBox) (Gießen, )
Die Patentverwertungsagentur der drei mittelhessischen Hochschulen TransMIT GmbH hat jüngst den Verkauf eines neuartigen Verfahrens zur Herstellung des Alzheimer-Wirkstoffs Memantine an die Frankfurter Merz Pharmaceuticals GmbH vermittelt.

Der von Merz entwickelte und zur Behandlung der moderaten bis schweren Alzheimer-Demenz zugelassene Wirkstoff Memantine (1-Amino-3,5-dimethyl-adamantan-hydrochlorid) konnte bislang nur unter erschwerten Synthesebedingungen hergestellt werden. Die drei notwendigen Arbeitsschritte Bromierung - Formamidierung – Amidspaltung führten zudem zu entsprechend großen Ausbeuteverlusten.

Memantine gehört chemisch zur Gruppe der Diamantoid-Derivate. Der Gießener Professor Peter R. Schreiner ist weltweit einer der wenigen Experten auf dem Gebiet der Diamantoidenchemie. Das von ihm erfundene Syntheseverfahren zur Herstellung von 1-Amino-3,5-dimethyl-adamantan-hydrochlorid ermöglicht ryv icx Lcahgtlvclteoumd hsf feus odltayorwwu Qyzvnkvpuyjyfvaoaaut.
