生物活性 H-Arg-Lys-OH 是由 L-精氨酸和 L-赖氨酸残基形成的二肽。
体外研究显示,到目前为止,仅少数生理相关的晚期糖基化终产物(AGEs)在离体组织中被鉴定出来,其中最值得注意的是赖氨酸-赖氨酸和赖氨酸-精氨酸交联生成的 AGEs。
The synthesis of the following dipeptides is described: L-arginyl-L-asparagine acetate, L-arginyl-L-glutamine acetate, L-arginyl-L-lysine diacetate, and L-arginyl-L-ornithine diacetate. The two former were prepared by coupling a mixed anhydride of α-carbobenzoxy-ω-nitro- L-arginine directly with L-asparagine or with L-glutamiae; catalytic hydrogenolysis of the resulting intermediates gave the dipeptides. The two others were obtained by combining α-carbobenzoxy-L-arginine with ω-carbobenzoxy- L-lysine methyl ester hydrochloride or with ω-carbobenzoxy-L-ornithine methyl ester hydrochloride in the presence of N,N′-dicyclohexyl-carbodiimide; saponification and hydrogenation was necessary to uncover the resulting dipeptides.
