    AbstractReducing sugars can react non-enzymatically with amino groups of proteins and lipids to form irreversibly cross-linked macroprotein derivatives called as advanced glycation end products (AGEs). Cross-linking modification of extracellular matrix proteins by AGEs deteriorate their tertiary structural integrity and function, contributing to aging-related organ damage and diabetes-associated complications, such as cardiovascular disease (CVD). Moreover, engagement of receptor for AGEs, RAGE with the ligands evoke oxidative stress generation and inflammatory, thrombotic and fibrotic reactions in various kinds of tissues, further exacerbating the deleterious effects of AGEs on multiple organ systems. So the AGE-RAGE axis is a novel therapeutic target for numerous devastating disorders. Several observational studies have shown the association of dietary consumption of fruits and vegetables with the reduced risk of CVD in a general population. Although beneficial effects of fruits and vegetables against CVD could mainly be ascribed to its anti-oxidative properties, blockade of the AGERAGE axis by phytochemicals may also contribute to cardiovascular event protection. Therefore, in this review, we focus on 4 phytochemicals (quercetin, sulforaphane, iridoids, and curcumin) and summarize their effects on AGE formation as well as RAGE-mediated signaling pathway in various cell types and organs, including endothelial cells, vessels, and heart.Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.
