摘要：
The present invention discloses compounds with carboxyl acid group and amide group which also containing the tertiary amino groups. The carboxyl acid group has a partial negative charge can attract the tertiary amino group with each other to form a quaternary ammonium salt structure, so that the compounds are easy to dissolve in water. Moreover, these compounds having a mushroom tyrosinase-inhibition effect and have the potential to use in the cosmetics for skin whitening.本發明揭示了一種具有羧酸基與醯胺基結構之化合物。其中，羧酸基帶部分負電荷(δ-)，而能和醯胺基之末端胺基相互吸引，進而形成四級胺塩的結構而促使此化合物易溶於水。並且，此具有羧酸基與醯胺基結構之化合物具有抑制酪胺酸酶(mushroom tyrosinase)效果，極有潛力應用在具備美白效用的化妝品產品上。
