Advanced glycation endproducts (AGEs) are formed when sugars react with peptides and proteins without the help of enzymes and by thermal processing of food such as baking and frying. AGEs and especially N ε-(carboxymethyl)lysine (CML) has been used as general key biomarkers for oxidative stress and a number of diseases associated with poor lifestyle. Herein we present the first synthetic pathway to the free zwitter ion of CML via a protected intermediate.
高级糖化终产物(AGEs)是糖在没有酶的帮助下与肽和蛋白质发生反应时,以及在烘烤和油炸等食品热加工过程中形成的。AGEs 尤其是 N δµ-(羧甲基)赖氨酸(CML)已被用作氧化应激和与不良生活方式相关的多种疾病的一般关键生物标志物。在此,我们首次提出了通过受保护中间体合成 CML 自由齐聚物离子的途径。
