Resveratrol-based compounds and neurodegeneration: Recent insight in multitarget therapy

Abstract

Neurodegenerative diseases (NDs) are characterized by gradual and progressive loss of selectively vulnerable populations of neurons, including death of neurons in different regions, leading to nervous system dysfunction. However, pharmacological treatments are only symptomatic, because the exact causes of the disease are not yet known. For this reason, in recent years, the research has been focused on the discovery of new molecules able to target neuropathological pathways involved in NDs. A great deal of attention has been paid to natural polyphenols due to their many biological effects and resveratrol has attracted special interest since its ability to interact simultaneously with the multiple targets implicated in NDs. Moreover, the structural simplicity of the stilbene core, the broad spectrum of possible modifications, and the improved synthetic strategies, made resveratrol an attractive chemical starting point for the search of new entities with extended therapeutic uses in NDs. In this review, a systematic update of the resveratrol-based compounds, and Structure-Activity Relationship analysis were provided as promising drug candidates for the treatment of NDs.
