Agents that stimulate nuclear translocation of Nrf2 protein and the subsequent increases in gene products that detoxify and eliminate cytotoxic metabolites are provided in a method for treating diabetic retinopathy or drusen formation in age-related macular degeneration. The structurally diverse agents that act on the Nrf2/ARE pathway induce the expression of enzymes and proteins that possess chemically versatile cytoprotective properties and are a defense against toxic metabolites and xenobiotics. Agents include certain electrophiles and oxidants such as a Michael Addition acceptor, diphenol, thiocarbamate, quinone, 1,2-dithiole-3-thione, butylated hydroxyanisole, flavonoid other than genistein, an isothiocyanate, 3,5-di-tert-butyl-4- hydroxytoluene, ethoxyquin, a coumarin, combinations thereof, or a pharmacologically active derivative or analog thereof.

La présente invention a trait à des agents de stimulation de la translocation nucléaire de la protéine Nrf2 et les croissances ultérieures dans des produits génétiques assurant la détoxication et l'élimination de métabolites cytotoxiques dans un procédé pour le traitement de la rétinopathie diabétique ou la formation de corps colloïdes dans la dégénérescence maculaire liée à l'âge. Les agents à structures diverses agissant sur la voie Nrf2/élément de réponse antioxydant induisent l'expression d'enzymes et de protéines qui possèdent des propriétés cytoprotectrices à versatilité chimique et constituent une défense contre des métabolites toxiques et des xénobiotiques. Les agents comprennent certains électrophiles et oxydants tels qu'un accepteur Michael d'addition, le diphénol, le thiocarbamate, le quinone, 2,2-dithiole-3-thione, le butylhydroxytoluène, le flavonoïde autre que la génistéine, un isothiocyanate, 3,5-di-tert-butyl-4-hydroxytoluène, l'éthoxyquine, une coumarine, leurs combinaisons, ou un dérivé à activité pharmacologique ou un analogue de ceux-ci.
