Multi-target-directed ligands (MTDLs) centered on β-secretase 1 (BACE-1) inhibition are emerging as innovative therapeutics in addressing the complexity of neurodegenerative diseases. A new series of donepezil analogues was designed, synthesized and evaluated as MTDLs against neurodegenerative diseases. Profiling of donepezil, a potent acetylcholinesterase (hAChE) inhibitor, into BACE-1 inhibition was achieved through introduction of backbone amide linkers to the designed compounds which are capable of hydrogen-bonding with BACE-1 catalytic site. In vitro assays and molecular modeling studies revealed the dual mode of action of compounds 4–6 against hAChE and BACE-1. Notably, compound 4 displayed potent hAChE inhibition (IC50 value of 4.11 nM) and BACE-1 inhibition (IC50 value of 18.3 nM) in comparison to donepezil (IC50 values of 6.21 and 194 nM against hAChE and BACE-1, respectively). Moreover, 4 revealed potential metal chelating property, low toxicity on SH-SY5Y neuroblastoma cells and ability to cross the blood–brain barrier (BBB) in PAMPA-BBB assay which renders 4 a potential lead for further optimization of novel small ligands for the treatment of Alzheimer's disease.

The enzymatic activity of butyrylcholinesterase (BChE) in the brain increases with the progression of Alzheimer's disease, thus classifying BChE as a promising drug target in advanced Alzheimer's disease. We used structure-based drug discovery approaches to develop potent, selective, and reversible human BChE inhibitors. The most potent, compound 3, had a picomolar inhibition constant versus BChE due to strong cation-π interactions, as revealed by the solved crystal structure of its complex with human BChE. Additionally, compound 3 inhibits BChE ex vivo and is noncytotoxic. In vitro pharmacokinetic experiments show that compound 3 is highly protein bound, highly permeable, and metabolically stable. Finally, compound 3 crosses the blood-brain barrier, and it improves memory, cognitive functions, and learning abilities of mice in a scopolamine model of dementia. Compound 3 is thus a promising advanced lead compound for the development of drugs for alleviating symptoms of cholinergic hypofunction in patients with advanced Alzheimer's disease.
