RT Journal Article T1 QuinoxalineTacrine QT78, a Cholinesterase Inhibitor as a Potential Ligand for Alzheimer’s Disease Therapy A1 Ramos Alonso, Eva A1 Palomino-Antolín, Alejandra A1 Bartolini, Manuela A1 Iriepa, Isabel A1 Moraleda, Ignacio A1 Diez-Iriepa, Daniel A1 Samadi, Abdelouahid A1 Cortina, Carol V. A1 Chioua, Mourad A1 Egea, Javier A1 Romero Martínez, Manuel Alejandro A1 Marco-Contelles, José AB 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.
