Abstract

The lack of a definitive treatment for Alzheimer's disease and the rapidly increasing prevalence of the disease have led to a crucial need for the development of new therapeutic agents that target key enzymes implicated in its pathogenesis. The inhibition of cholinesterase represents one of the important therapeutic strategies in the treatment of Alzheimer’s disease. Therefore, this present study investigated the in silico and in vitro cholinesterase inhibition activities of hydrazone derivatives, which have significant biological activity potential. This study revealed that molecule 7 displayed the most effective inhibition activity against cholinesterase enzymes, with an IC50 value of 1.95±0.20 µM for AChE and 6.08±0.42 µM for BChE. However, in silico studies revealed that molecule 6 exhibited the greatest affinity towards cholinesterase enzymes, while molecules 5 and 7 exhibited a moderate affinity. The in vitro results suggest that molecule 7 may be a promising scaffold for the development of new anticholinesterase candidates.
