Advancedglycationendproducts (AGEs) are compounds formed by non-enzymatic chemical reactions following the bonding of sugars to proteins or lipids during diabetes, uremia, aging, rheumatic arthritis, and other conditions. A receptor for the AGEs (RAGE) binds certain members of this class to initiate cell signaling.[1][2] Pentosidine is a well-characterized natural AGE that is often used as a biomarker for the production of all AGEs. While pentosidine can be measured in urine, the majority of this AGE is catabolized before excretion.[3] Reference:[1]. Neeper, M., Schmidt, A.M., Brett, J., et al.

Advancedglycationendproducts (AGEs) are compounds that are produced through non-enzymatic chemical reactions when sugars bond with proteins or lipids, occurring in conditions such as diabetes, uremia, aging, and rheumatic arthritis. A specific receptor, known as RAGE, interacts with select AGEs to trigger cell signaling. Pentosidine, a prominently studied natural AGE, serves as a common biomarker for assessing AGE production. Although pentosidine levels can be determined through urine analysis, it is predominantly broken down prior to excretion.
3,5-Di-O-caffeoylquinic acid methyl ester exhibits potent inhibitory activities against the formation of advancedglycationendproducts (AGEs); it exhibits cytotoxicity actions against human cervix carcinoma HeLa cells. 3,5-Di-O-caffeoylquinic acid methyl ester shows high efficiency and low toxicity with antivirus activity against RSV.
