A peptide containing the cell adhesion sequence, Arg-Gly-Asp-Ser, was attached to 2,3-phytanoxypropaneamine (NH2-DPhy), an archaebacterial lipid model. The peptide moiety contained a thioester group at its C-terminus and was synthesized by the solid-phase method. The thioester group was activated with silver ions to yield a peptide bond between the peptide and the archaebacterial lipid. The resulting
将含有细胞粘附序列的肽Arg-Gly-Asp-Ser连接到古细菌脂质模型2,3-phytanoxypropaneamine(NH 2 -DPhy)。肽部分在其C末端含有硫酯基,并通过固相方法合成。硫酯基团被银离子活化,以在肽和古细菌脂质之间产生肽键。超声处理时,所得的肽-脂质缀合物形成稳定的脂质体。
