The multitarget-directed ligands approach represents a potential strategy to provide effective treatments for Alzheimer's disease (AD) given its multifactorial pathology. Herein, a series of N-benzyl piperidine derivatives were designed, synthesized, and biologically characterized for dual inhibitions of histone deacetylase (HDAC) and acetylcholinesterase (AChE). Among the compounds tested, d5 and d10 exhibited dual enzyme inhibitions (d5: HDAC = 0.17 μM, AChE = 6.89 μM, d10: HDAC = 0.45 μM, AChE = 3.22 μM), and both compounds showed activities on scavenging free radical, metal chelating, and inhibiting Aβ aggregations. More importantly, both compounds exhibited promising neuroprotective activities in PC-12 cells and good AChE selectivity. Collectively, the multifunctional profiles of compound d5 and d10 encourage further optimization and exploration to develop more potent analogues as potential treatments for AD.

The present article describes the successful performance of crossed aldol reactions of the CF-containing pseudo-C symmetric cyclic imide with various aldehydes. The utilization of HMPA as an additive attained the preferential formation of the -products in good to excellent yields, which contrasts with our previous method without this additive, proceeding to furnish the corresponding -isomers. The effective participation of ketones and α,β-unsaturated carbonyl compounds in reactions with this imide was also demonstrated to expand the application of this imide.

The pathogenic complexity of Alzheimer's disease (AD) demands the development of multitarget-directed agents aiming at improving actual pharmacotherapy. Based on the cholinergic hypothesis and considering the well-established role of butyrylcholinesterase (BuChE) in advanced stages of AD, the chemical structure of the acetylcholinesterase (AChE) inhibitor drug donepezil (1) was rationally modified for the design of new N-benzyl-piperidine derivatives (4a-d) as potential multitarget-direct AChE and BuChE inhibitors. The designed analogues were further studied through the integration of in silico and in vitro methods.

Article Synopsis
  • CDK6 is a crucial protein kinase involved in the cell cycle, making it a potential target for cancer treatments, especially for breast cancer, and this study aims to identify promising new compounds through a drug repurposing strategy.
  • The research found two compounds that bind more effectively to CDK6 than the common drug abemaciclib, showing significant binding affinities and similar absorption, distribution, metabolism, and excretion (ADME) properties.
  • Molecular dynamics simulations suggested that these compounds maintain stability and interactions with CDK6, indicating their potential as effective inhibitors that warrant further laboratory testing.
