Multitarget neuroprotective effects of β-sitosterol in diabetes-associated neurodegeneration: a coupled experimental/computational study
Abstract
Diabetes often leads to neurodegenerative complications that complicate treatment. Exploring dietary components with neuroprotective properties could offer new therapeutic avenues. This study aimed to evaluate the neuroprotective potential of β-sitosterol against diabetes-associated neurodegenerative complications using a combined in silico and in vivo approach. β-Sitosterol exhibited significant neuroprotective effects in a diabetic neuropathy model. Compared to sitagliptin, β-sitosterol demonstrated stronger binding affinities to DPP4, acetylcholinesterase, and butyrylcholinesterase, along with more stable molecular dynamics profiles. In vivo, β-sitosterol treatment markedly improved glucose tolerance, insulin sensitivity, lipid profiles, and antioxidant capacity. Histological analysis revealed reduced neurodegenerative changes and enhanced neuronal integrity in the cortex and hippocampus. These findings suggest β-sitosterol as a promising therapeutic agent for managing diabetic neurodegeneration, warranting further research and potential clinical application.
