Lipidic amino acids 1a, c and dimer 1b were coupled to highly hydrophilic compounds, lactic, glycolic and gluconic acids and protected gulonic acid, yielding conjugates 1d,f,h,i,j,l and o. After carboxyl deprotection, acids e,g and m and were obtained. Physico-chemical investigations of these compounds were carried out using proton nuclear magnetic resonance.

脂质氨基酸1a,c和二聚体1b与高度亲水的化合物,乳酸,乙醇酸和葡萄糖酸以及受保护的古洛糖酸偶联,得到缀合物1d,f,h,i,j,l和o。羧基脱保护后,得到酸e,g和m 1和m。使用质子核磁共振对这些化合物进行了物理化学研究。化学位移对浓度的图揭示了在高浓度下形成聚集体或胶束而在低浓度下形成单体。
