Many other Nrf2-inducing drugs are protective in animal models of Parkinson’s disease including triterpenoids (2-cyano-3-,12-dioxooleana-1,9(11)-dien-28-oic acid (CDDO) derivatives) [69,70], curcumin [56,71], 3H-1,2-dithiole-3-thione [72], carnosic acid [73] and resveratrol [74,75,76,77] (see [2] for further compounds). This evidence concerns the gene NFE2L2 and Parkinson disease.
