Anticholinesterase activities of novel isoindolin-1,3-dione-based acetohydrazide derivatives: design, synthesis, biological evaluation, molecular dynamic study.

ABSTRACT: In pursuit of developing novel cholinesterase (ChE) inhibitors through molecular hybridization theory, a novel series of isoindolin-1,3-dione-based acetohydrazides (compounds 8a-h) was designed, synthesized, and evaluated as possible acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitors. In vitro results revealed IC₅₀ values ranging from 0.11 ± 0.05 to 0.86 ± 0.02 µM against AChE and 5.7 ± 0.2 to 30.2 ± 2.8 µM against BChE. A kinetic study was conducted on the most potent compound, 8a, to ascertain its mode of inhibition, revealing its competitive mode against AChE. Furthermore, the binding interaction modes of the most active compound within the AChE active site was elucidated. Molecular dynamics simulations of compound 8a were performed to assess the stabilit
