Resumen

This paper describes our preliminary results on the ADMET, synthesis, biochemical evaluation, and molecular modeling of racemic HuperTacrines (HT), new hybrids resulting from the juxtaposition of huperzine A and tacrine for the potential treatment of Alzheimer’s disease (AD). The synthesis of these HT was executed by Friedländer-type reactions of 2-amino-6-oxo-1,6-dihydropyridine-3-carbonitriles, or 7-amino-2-oxo-1,2,3,4-tetrahydro-1,6-naphthyridine- 8-carbonitriles, with cyclohexanone. In the biochemical evaluation, initial and particular attention was devoted to test their toxicity on human hepatoma cells, followed by the in vitro inhibition of human cholinesterases (hAChE, and hBuChE), and the kinetics/mechanism of the inhibition of the most potent HT; simultaneous molecular modeling on the best HT provided the key binding interactions with the human cholinesterases. From these analyses, (±)-5-amino-3-methyl- 3,4,6,7,8,9-hexahydrobenzo[b][1,8]naphthyridin-2(1H)-one (HT1) and (±)-5-amino-3-(2,6-dichlorophenyl)-3,4,6,7,8,9- hexahydrobenzo[b][1,8]naphthyridin-2(1H)-one (HT3) have emerged as characterized by extremely low liver toxicity reversible mixed-type, selective hAChE and, quite selective irreversible hBuChEIs, respectively, showing also good druglike properties for AD-targeted drugs.
