Inhibitory effect of vanillic acid on methylglyoxal-mediated glycation in apoptotic Neuro-2A cells.

Methylglyoxal is a reactive dicarbonyl compound generated as an intermediate of glycolysis during the physical glycation in the diabetic condition. It is considered to be a potent precursor of advanced glycation end products (AGEs) formation. Methylglyoxal itself and methylglyoxal-derived AGEs have been commonly implicated in the development of diabetic neuropathy.

Cytoprotective effects of phenolic acids on methylglyoxal-induced apoptosis in Neuro-2A cells.

In the process of glycation, methylglyoxal is a reactive dicarbonyl compound physiologically generated as an intermediate of glycolysis, and is found in high levels in blood or tissue of diabetic models. Biological glycation has been commonly implicated in the development of diabetic microvascular complications of neuropathy. Increasing evidence suggests that neuronal cell cycle regulatory failure followed by apoptosis is an important mechanism in the development of diabetic neuropathy complication.
