Ações bioquímicas/fisiológicas

(R)-(+)-α-Lipoic acid was shown to significantly increase pyruvate oxidation while abrogating fatty acid oxidation in rat hepatocytes. These effects make R-(+)-α-Lipoic acid a promising treatment option for the treatment of Type II diabetes.[1] It is a biological antioxidant with prooxidant activities[2][3], its therapeutic potential is widely investigated[4][5][6], e.g. in the treatment for Alzheimer′s disease.[7]

R-(+)-alpha-lipoic acid (R-LA) is the naturally occurring enantiomer of LA. It is a strong antioxidant and cofactor of key metabolic enzyme complexes catalyzing the decarboxylation of alpha-keto acids. Racemic LA (rac-LA) has shown promise in treating diabetic polyneuropathy, and some

Growing evidence suggests that α-lipoic acid (LA) has neuroprotective effects in various pathological conditions including brain ischemia and neurodegeneration. While anti-oxidative activity has been thought to play a central role in LA-mediated neuroprotection, the precise mechanism and the effect of

alpha-Lipoic acid, which plays an essential role in mitochondrial dehydrogenase reactions, has recently gained considerable attention as an antioxidant. Lipoate, or its reduced form, dihydrolipoate, reacts with reactive oxygen species such as superoxide radicals, hydroxyl radicals, hypochlorous acid, peroxyl radicals
