Abstract :
Here we report that bis(7)-tacrine, a novel acetylcholinesterase inhibitor, exerts neuroprotective effects by inhibition of nitric oxide synthase. In cortical neurons at 12 days in vitro, bis(7)-tacrine concentration-dependently reduced cell death induced by glutamate, beta-amyloid and L-arginine, but not by nitric sodium nitroprusside. N-monomethyl-L-arginine, a nitric oxide synthase inhibitor, also prevented the former three types but not the last type of the cytotoxicity; however, nitric oxide scavengers blocked all of these insults, indicating that nitric oxide mediated these neuronal injuries. Furthermore, with nitric oxide synthase activity assays, it was found that bis(7)-tacrine not only suppressed the activation of nitric oxide synthase caused by glutamate in cortical neurons, but also directly inhibited the activity of nitric oxide synthase in vitro. |
