چکیده
Introduction Idebenone [2,3-dimethoxy-5-methyl-6-(10-hydroxydecyl)-1,4-benzoquinone] is a synthetic analogue of coenzyme Q10 (CoQ10), the vital cell membrane antioxidant and essential constituent of the ATP-producing mitochondrial electron transport chain (ETC). Idebenone is a potent antioxidant, with the ability to operate under low oxygen tension situations. Because of its ability to inhibit lipid peroxidation, idebenone protects cell membranes and mitochondria from oxidative damage. Its antioxidant properties protect against cerebral ischemia and nerve damage in the central nervous system. Idebenone also interacts with the ETC, preserving ATP formation in ischemic states. This compound has also been shown to stimulate nerve growth factor, a characteristic that could be important in the treatment of Alzheimer’s and other neurodegenerative diseases.

متن کاملIdebenone and reduced cardiac hypertrophy in Friedreich's ataxia.
BACKGROUND Friedreich's ataxia encodes a protein of unknown function, frataxin. The loss of frataxin is caused by a large GAA trinucleotide expansion in the first intron of the gene, resulting in deficiency of a Krebs cycle enzyme, aconitase, and of three mitochondrial respiratory chain complexes (I-III). This causes oxidative stress. Idebenone, a short chain quinone acting as an antioxidant, h...
متن کاملEffect of long-term oral treatment with L-arginine and idebenone on the prevention of stroke-like episodes in an adult MELAS patient.
INTRODUCTION Mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) is a maternally-inherited multisystem disorder. Mitochondrial angiopathy mediated by nitric oxide, a metabolite of L-arginine, is among the proposed pathophysiologic mechanisms of stroke-like episodes (SLEs) in MELAS. There are very few reports on long-term prevention of SLEs with oral L-arginine and ide...
متن کاملEfficacy of Idebenone to Preserve Respiratory Function above Clinically Meaningful Thresholds for Forced Vital Capacity (FVC) in Patients with Duchenne Muscular Dystrophy
BACKGROUND Patients with DMD experience progressive restrictive respiratory disease and eventual respiratory failure. Standard of care guidelines command changes in disease management when forced vital capacity percent of predicted (FVC% p) falls below clinically relevant thresholds. The Phase 3 DELOS trial in patients with DMD demonstrated that idebenone reduces the loss of peak expiratory flo...
متن کاملIdebenone acts against growth of Helicobacter pylori by inhibiting its respiration.
Growth of Helicobacter pylori was inhibited by the quinones, idebenone, duroquinone, menadione, juglone, and coenzyme Q(1) at low concentrations of 0.8 to 3.2 mug/ml. Idebenone specifically inhibited H. pylori growth by inhibiting respiration and decreasing the cellular ATP level. The respiratory inhibition was accompanied by reduction of idebenone by the H. pylori cells.
