Use of Idebenone for the preservation of compositions

摘要

The use of idebenone (I) (i.e. 6-(10-hydroxydecyl)-2,3-dimethoxy-5-methyl-1,4-benzoquinone) or its derivative (I') is claimed in cosmetic or topical dermatological preparations. ACTIVITY : Dermatological; antiinflammatory; antiallergic; immunosuppressive. MECHANISM OF ACTION : Antioxidant; radical scavenger; apoptosis inhibitor. In macrophage-LDL antioxidant tests (I) at 10 MicroM completely prevented lipid peroxide formation after 8 and 24 hours, and was markedly more effective than ascorbic acid at 50 mu M, alpha -tocopherol at 100 mu M or glutathione at 50 mu M.
