Abstract:

Objective  Dimebon is an antihistamine compound which has been proposed to treat neurodegenerative disorders, but the mechanism remain elusive. To explore Dimebon effection on Alzheimer's disease and Huntington's disease. Method   Membrane currents were measured by using whole cell patch clamp techniques.  the influence ofdifferent concentration of Dimebon on NMDA -activated currents in primary Medium Spiny Striatal Neuronal cultures (MSN) from wild type (WT) mice were studied.  Results  1~50 μmol/L Dimebon inhibited NMDA activated currents, but 0.1~0.5μmol/L increased NMDA activated currents.   Conclusion    Dimebon has dual function on NMDA receptors.

Key words: Dimebon,  , Medium spiny striatal neurons, NMDA receptor
