Drug repositioning or repurposing, i.e. identifying new indications for existing drugs, has gained increasing attention in the recent years. This approach enables the scientists to discover "new targets" for known drugs in a cost and time efficient manner. Glycation, the non-enzymatic reaction of sugars with proteins or nucleic acids to form early glycation (Amadori or fructosamine) products, i...

Non-enzymatic glycosylation, commonly known as glycation, is a physiological process that may be intensified by endogenous and exogenous factors. The accumulation of advanced glycation end products (AGEs) effects negatively the aging skin, modifying biochemical, structural, morphological properties skin. study aimed to describe mechanisms AGEs on cells epidermis, dermis, vascular endothelium, w...

Abstract Glycation is a spontaneous post-translational modification of lysine, arginine, and the N-terminus proteins. Protein glycation closely related to pathogenesis human diseases, including diabetes, Alzheimer’s disease, renal cancer. The levels advanced end products (AGEs) are positively correlated with progression many diseases. However, it remains challenging analyze glycation-related pr...

Patients with diabetes mellitus are at increased risk of restenosis after coronary artery stenting. Chronic hyperglycemia is associated with advanced glycation end products excessive production. There are data that in-stent restenosis in patients with diabetes mellitus may be related to plasma level of advanced glycation end products. One of the reasons for this is that protein glycation by alt...

Piper betle Linn. is a Pan-Asiatic plant having several beneficial properties. Protein glycation and advanced glycation end products (AGEs) formation are associated with different pathophysiological conditions, including diabetes mellitus. Our study aims to find the effect of methanolic extract of P. betle leaves on in vitro protein glycation in bovine serum albumin (BSA)-glucose model. The ext...

lysozyme is a bactericidal enzyme whose structure and functions change in diabetes. chemical chaperones are small molecules including polyamines (e.g. spermine), amino acids (e.g. l-lysine) and polyols (e.g. glycerol). they can improve protein conformation in several stressful conditions such as glycation. in this study, the authors aimed to observe the effect of l-lysine as a chemical chaperon...

This article reviews glycation stress as a factor linked to age-related diseases and functional and structural alterations of the skin. Photo-aging and glycation stress are major causes of skin deterioration. Glycation occurs when a reducing sugar, such as glucose or fructose, combines with a protein in a non-enzymatic reaction forming a glycated protein. Further reactions form advanced glycati...

Glyceraldehyde (GLA) was determined in glucose degradation and glycation. GLA was detected as a decahydroacridine-1,8-dione derivative on reversed phase HPLC using cyclohexane-1,3-dione derivatizing reagent. The glucose-derived GLA level was higher than the glycation-derived GLA level, because GLA was converted to intermediates and advanced glycation end products (AGE) in glycation. GLA was als...

Glycation is a nonenzymatic process in which proteins react with reducing sugar molecules. The identification of glycation sites in protein may provide guidelines to understand the biological function of protein glycation. In this study, we developed a computational method to predict protein glycation sites by using the support vector machine classifier. The experimental results showed that the...

Abstract When glucose and Amadori products are auto-oxidized, glycation occurs, resulting in the formation of early (Amadori) late advanced end (AGEs), as well free radicals. Glycation an increase radical activity induce diabetic complications. Antioxidant antiglycation compounds may aid prevention oxidation glycation. The goal this study was to assess antioxidant capacity C-phycocyanin (C-PC) ...
