Chemical identity and properties
Idebenone
Idebenone is a member of the class of 1,4-benzoquinones which is substituted by methoxy groups at positions 2 and 3, by a methyl group at positions 5, and by a 10-hydroxydecyl group at positions 6. Initially developed for the treatment of Alzheimer's disease, benefits were modest; it was subsequently found to be of benefit for the symptomatic treatment of Friedreich's ataxia. It has a role as a ferroptosis inhibitor and an antioxidant. It is a member of 1,4-benzoquinones and a primary alcohol. — ChEBI
