Abstract
We report the synthesis and relevant pharmacological properties of the quinoxalinetacrine (QT) hybrid QT78 in a project targeted to identify new non-hepatotoxic tacrine derivatives for Alzheimer’s disease therapy. We have found that QT78 is less toxic than tacrine at high concentrations (from 100 μM to 1 mM), less potent than tacrine as a ChE inhibitor, but shows selective BuChE inhibition (IC50 (hAChE) = 22.0 ± 1.3 μM; IC50 (hBuChE) = 6.79 ± 0.33 μM). Moreover, QT78 showed effective and strong neuroprotection against diverse toxic stimuli, such as rotenone plus oligomycin-A or okadaic acid, of biological significance for Alzheimer’s disease.
