Indeed, some of them, such as resveratrol (RES), have been examined in clinical trials. Nevertheless, their success has been scarce mainly due to their low bioavailability. In this study, we found serendipitously that O-silyl RES derivatives exerted a better neuroprotective activity than resveratrol itself and decided to explore them as potential drugs for neurodegenerative and neurological diseases. We have also designed and prepared a series of O-silyl RES prodrugs to improve their bioavailability. We found that di-triethylsilyl and di-triisopropylsilyl RES derivatives were better in vitro neuroprotective and anti-inflammatory agents than RES. Among these derivatives and their corresponding acyl-, glycosyl- and carbamoyl-prodrugs, 3,5-triethylsilyl-4'-(6″-octanoylglucopyranosyl) resveratrol 26 showed the best profile on toxicity and neuroprotective activity in zebra fish embryo. Compound 26 was also capable of reducing the loss of motor coordination in a 3-nitropropionic acid mice model of Huntington's disease, in a similar way to RES. However, 26 diminished pro-inflammatory cytokine IL-6 to a higher extent than RES and improved the latency to fall in the rotarod test by 10% with respect to RES. Finally, we investigated 26 and RES as potential treatments on an experimental autoimmune encephalomyelitis (EAE) multiple sclerosis mice model. We observed that, in a therapeutic regimen, 26 significantly diminished the progression of EAE severity and reduced the percentage of animals with moderate to severe clinical score, whereas RES showed no improvement.
