A series of analogues designed to assess the importance of the amide bond in the dipeptide sweetener L-aspartyl-L-phenylalanine methyl ester has been synthesized and tested. The peptide bond was methylated, replaced by an ester bond, or reversed. all of these modifications produced compounds that did not have a sweet taste. We conclude that the steric, electronic, and directional characteristics of
合成并测试了一系列旨在评估二肽甜味剂L-天冬氨酰-L-苯丙氨酸甲酯中酰胺键重要性的类似物。肽键被甲基化,被酯键取代或被反向。所有这些修饰产生的化合物没有甜味。我们得出结论,酰胺键的空间,电子和方向特征对于二肽甜味剂的生物活性至关重要。
