A series of analogues of the dipeptide sweetener L-aspartyl-L-phenylalanine methyl ester having hydroxy and/or methoxy substitution on the aromatic ring was synthesized and tasted. The introduction of a methoxy group in the para position of the aromatic ring of the peptide sweetener is crucial to the reduction or destruction of the sweet taste. The effects of substituents in the ortho or meta position
合成并品尝了在芳香环上具有羟基和/或甲氧基取代的二肽甜味剂L-天冬氨酰-L-苯丙氨酸甲酯的一系列类似物。在肽甜味剂的芳环对位引入甲氧基对减少或破坏甜味至关重要。在邻位或间位的取代基的作用不那么明显。在邻甲氧基取代的情况下,所得类似物的甜度仅比母体二肽甜味剂略低。
