The present invention is directed in particular to dipeptide-like compounds derived from functionally substituted amino acids, having fatty acid chains bound thereto through amidification of the amine functional groups of said dipeptide-like compounds, one end portion of which bears an accessory functional side chain spacer, with the other end portion being an acid group either in neutral or charged state.
Compounds of the present invention have immunomodulating properties like adjuvants. In addition, compounds of the invention can be grafted on a given antigen in order to modulate or tune the immune response or can be equally grafted on a pharmaceutical carrier to enhance the therapeutic effect or targeting thereof. Accordingly, compounds of the invention find use in human and veterinary medicine both as immunogens and diagnostic tools.
本发明特别针对从功能取代的
氨基酸中衍生出来的二肽类化合物,其通过酰胺化作用将
脂肪酸链结合到所述二肽类化合物的胺基官能团上,其中一端部分具有辅助功能侧链间隔物,而另一端部分是一个酸基,可以是中性或带电状态。本发明的化合物具有类似佐剂的免疫调节特性。此外,本发明的化合物可以嫁接到给定的抗原上,以调节或调整免疫反应,也可以同样嫁接到药物载体上,以增强其治疗效果或靶向性。因此,本发明的化合物在人类和兽医医学中均可用作免疫原和诊断工具。
