  New developments in redox chemical delivery systems by means of 1,4-dihydroquinoline-based targetor: Application to galantamine delivery to the brain

  摘要：

  The therapeutic efficiency of palliative treatments of AD, mostly based on acetylcholinesterase (AChE) inhibitors, is marred by serious adverse effects due to peripheral activity of these AChE inhibitors. In the literature, a redox-based chemical delivery system (CDS) has been developed to enhance drugs distribution to the brain while reducing peripheral side effects. Herein, we disclose two new synthetic strategies for the preparation of 1,4-dihydroquinoline/quinolinium salt redox-based systems particularly well designed for brain delivery of drugs sensitive to alkylation reactions. These strategies have been applied in the present case to the AChE inhibitor galantamine with the aim of alleviating adverse effects observed with cholinergic AD treatment. The first strategy is based on an intramolecular alkylation reaction as key step, whilst the second strategy relies on a useful coupling between galantamine and quinolinium salt key intermediate. In the course of this work, polymer-supported reagents and a solid-phase synthesis approach revealed to be highly helpful to develop this redox-based galantamine CDS. (C) 2014 Elsevier Masson SAS.
