We report herein the design, synthesis, biological evaluation, and molecular modelling of new inhibitors of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), able to block Ca⁺² channels also showing antioxidant and neuroprotective activities. The new MTDL, dialkyl 2,6-dimethyl-4-(4-((5-aminoalkyl)oxy)phenyl)-1,4-dihydropyridine-3,5-dicarboxylate <b>3a-p</b>, have been obtained via Hantzsch reaction from appropriate and commercially available precursors. Pertinent biological analysis has prompted us to identify MTDL <b>3h</b> [dimethyl-4-(4-((5-(4-benzylpiperidin-1-yl)pentyl)oxy)phenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate] as an attractive inhibitor of AChE (1.8 μM) and BuChE (2 μM), Ca⁺² channel antagonist (47.72% at 10 μM), and antioxidant (2.54 TE) agent, showing significant neuroprotection 28.68% and 38.29% against H₂O_2, and O/R, respectively, at 0.3 μM, thus being considered a hit-compound for further investigation in our search for anti-Alzheimer’s disease agents.
