Application

α-LA can reinstate endothelial activities and alleviate oxidative stress in high-fat fed diabetic rats4. It has also been used to analyze ROS production in astrocytes5.

Biochem/physiol Actions

Antioxidant and coenzyme needed for the activity of enzyme complexes such as pyruvate dehydrogenase and glycine decarboxylase.
Antioxidant and coenzyme needed for the activity of enzyme complexes such as those of pyruvate dehydrogenase and glycine decarboxylase. Exogenous thioctic acid is reduced intracellularly by two or more enzymes. The reduced form then influences a number of cell processes by direct radical scavenging, recycling of other antioxidants, increasing glutathione synthesis, and modulating transcription factor activity particularly that of NF-κB. Decreases the phagocytosis of myelin by macrophages.

Preparation Note

(±)-α-Lipoic acid (α-LA) is soluble in ethanol at 50 mg/ml
