Resumen:
Alzheimer´s disease (AD) is a multifactorial neurodegenerative disorder. Acetylcholinesterase (AChE) inhibitors constitute a pharmacotherapeutic strategy for AD treatment. Resveratrol has anti-inflammatory, neuroprotective, anticarcinogenic, and antioxidant properties. This study aimed to evaluate the AChE inhibitory properties and the protective role against oxidative stress damage of 5 resveratrol analogs (M1 to M5) in SH-SY5Y cells. The studied compounds were not cytotoxic in a wide range of concentrations. Treatment of SH-SY5Y cells at the AChE´s IC50s concentration significantly decreased the AChE enzyme activity in live cells. Through the dichlorofluorescein (DCF) assay, 3 compounds decreased the endogenous production of reactive oxygen species (ROS). These results demonstrate that, in addition to their action as biologically active AChE inhibitors, some resveratrol derivatives exhibit neuroprotective effects against endogenous ROS production.
