Abstract
The prevalence and incidence of diabetes mellitus (DM) are increasing worldwide bringing with it a significantly higher rate of complications. Various mechanisms such as carbonyl stress, polyol pathway, oxidative stress, hexosamine pathways, diacylglycerol/protein kinase-C activation, etc., are responsible for the pathogenesis of DM and its complications. Persistent hyperglycaemia and inhibition of metabolising and detoxifying enzymes lead to the excessive synthesis of carbonyl compounds such as methylglyoxal, glyoxal, and 3-deoxyglucosone, resulting in carbonyl stress. The substrates, metabolizing and detoxifying enzymes of carbonyl compounds are discussed. The mechanistic roles of carbonyl compounds and advanced glycation end products (AGEs) in atherosclerosis, insulin resistance, thrombogenicity, and endothelial dysfunction in animal and cell culture model of DM and patients with DM are summarised. Because of the essential role of carbonyl stress, therapeutics are aimed at scavenging, metabolizing, detoxifying, and inhibiting carbonyl compounds or AGEs so that their harmful effects are minimized. Clinically used drugs, plants extracts and miscellaneous chemical with antiglycation properties are used in an animal model of DM to alleviates the impact of carbonyl compounds. Extensive clinical trials with derivatisation of available antiglycation agents to increase the bioavailability and decrease side effects are warranted further.
