Neurodegenerative diseases (NDDs) share several physiopathological mechanisms such as the presence of aberrant protein aggregates, oxidative stress and neuroinflammation. Given the role of these factors in the development of NDDs, compounds able to regulate them simultaneously are of great interest. At physiological conditions, the main route to combat oxidative stress and neuroinflammation is the Nrf2/EpRE pathway. Besides, it has been observed, that the Nrf2 pathway is deregulated in neurodegenerative disorders1. Based on this hypothesis we carried out the design, synthesis and pharmacological evaluation of a new family of Nrf2 inducers with complementary activities for the treatment of NDDs2. Newly developed compounds were able to induce the Nrf2-EpRE pathway, and also demonstrated a complementary anti-inflammatory effect that was not dependent on the Nrf2 inducing properties . Besides the compounds showed an interesting neuroprotective effect against in vitro and ex vivo model models of oxidative stress and toxicity induced by protein aggregation. Altogether, these results indicate these compounds are of interest to be further evaluated in in vivo models of NDDs.
