This study explores novel multitarget-directed ligands (MTDLs) showing anticholinesterase, antioxidant, neuroprotective, and calcium channel inhibitory activities, as promising compounds for Alzheimer's disease (AD) treatment. The rational design combined dihydropyridines (DHPs), known for calcium channel blocking and neuroprotective properties, with tacrine, a cholinesterase inhibitor. The key innovation of this work lies in the one-pot tandem Hantzsch multicomponent/click reaction used to synthesize new 18 DHPs IIIa-r. This sustainable and original approach aligns with green chemistry principles by reducing waste, energy consumption, and derivatives formation. Notably, DHP IIIj and IIIk demonstrated a multitarget profile and effectively reversed scopolamine-induced amnesia in a mouse model, showcasing its antiamnesic properties. These results suggested that DHP IIIj and IIIk hold promise as innovative therapeutic candidates for AD, validating the potential of MTDL strategy and highlighting the one-pot tandem synthesis as a significant advancement in medicinal chemistry.
