Alpha-lipoic acid is a naturally occurring substance, essential for the function of different enzymes that take part in mitochondria's oxidative metabolism. It is believed that alpha-lipoic acid or its reduced form, dihydrolipoic acid have many biochemical functions acting as biological antioxidants, as metal chelators, reducers of the oxidized forms of other antioxidant agents such as vitamin ...
Reactive oxygen species (ROS) are increasingly believed to be important intracellular signaling molecules in mitogenic pathways involved in the pathogenesis of glomerulonephritis (GN). We explored the effects of the antioxidants alpha-lipoic acid and N-acetyl-l-cysteine on ERK activation in cultured mesangial cells and the role of ERK activation in the severity of glomerular injury in a rat mod...
After evaluating the prevalence of early endothelial dysfunction, as measured by means of reactive hyperemia in adolescents with type 1 diabetes, we started a 6-month, double-blind, randomized trial to test the efficacy of an antioxidant diet (± alpha-lipoic acid supplementation) to improve endothelial dysfunction. Seventy-one children and adolescents, ages 17 ± 3.9 yrs, with type 1 diabetes si...
In view of the theory that alpha-lipoic acid effectively prevents cochlear cells from injury caused by various factors such as cisplatin and noise, this study examined whether alpha-lipoic acid can prevent kanamycin-induced ototoxicity. To this end, healthy BALB/c mice were injected subcutaneously with alpha-lipoic acid and kanamycin for 14 days. Auditory brainstem response test showed that inc...
Introduction Alpha-lipoic acid (ALA – also known as thioctic acid) was discovered in 1951 as a molecule that assists in acyl-group transfer and as a coenzyme in the Krebs cycle. In the 1980s, the scientific community realized alpha-lipoic acid is a powerful antioxidant. Several qualities distinguish alpha-lipoic acid from other antioxidants: ALA can be synthesized by animals and humans;1 it neu...
OBJECTIVE: To evaluate the efficacy and safety of oral treatment with the antioxidant alpha-lipoic acid (ALA) in NIDDM patients with cardiac autonomic neuropathy (CAN), assessed by heart rate variability (HRV). RESEARCH DESIGN AND METHODS: In a randomized, double-blind placebo-controlled multicenter trial (Deutsche Kardiale Autonome Neuropathie [DEKAN] Study), NIDDM patients with reduced HRV we...
Alpha lipoic acid, or just lipoic acid (LA), is a unique and potent antioxidant. It can deliver antioxidant activity in both fatand water-soluble mediums, and it is capable of having an antioxidant effect in both its oxidized (LA) and reduced (DHLA [dihydrolipoic acid]) forms (Goraca et al., 2011). This effectively allows LA to deliver its antioxidant effect to any cell or tissue type, as well ...
Cadmium (Cd) is a well-known human carcinogen and a potent nephrotoxin. The protective effects of alpha-lipoic acid and melatonin against cadmium (Cd) induced oxidative stress to erythrocytes in rats were evaluated. One hundred male albino rats were divided into five groups containing 20 rats each. Group I: (control) administered distilled water. Group II :( Cadmium exposed group) received cadm...
BACKGROUND Amelioration of insulin resistance could improve both glycaemic control and cardiovascular risk factors in patients with type 2 diabetes mellitus. Alpha-lipoic acid has been shown to improve insulin action after parenteral administration. OBJECTIVE the aim of the study was to assess the effect of oral administration of alpha-lipoic acid on insulin sensitivity in patients with type ...
