    • PURPOSE: Provided are a recombinant of a synthetic peptide bound to a fatty acid and a phospholipid membrane and a preparation method thereof. The recombinant has an increased stability, and is used as a stable immunogenic vaccine material (for antigen peptide) and is used to effectively deliver a drug (for low molecular weight of the peptide exhibiting a pharmacological activity). CONSTITUTION: The preparation method comprises the steps of : (1) binding the fatty acid to the hydrophilic peptide at C-terminal, N-terminal or an intermediate chain thereof to prepare a lipopeptide; and (2) recombining the lipopeptide of the step (1) and lipid or phospholipid mixture. The peptide may be p26 peptide (preS2 (120-145)) having a sequence represented by SEQ ID NO : 1, a peptide which plays a role of an epitope or low molecular weight of the peptide exhibiting a pharmacological activity, and the fatty acid is selected from the group consisting of palmitic acid, myristic acid, stearic acid, oleic acid and arachidonic acid.
    • 目的:提供与脂肪酸和磷脂膜结合的合成肽的重组体及其制备方法。 重组体具有增加的稳定性,并且用作稳定的免疫原性疫苗材料(用于抗原肽),并用于有效递送药物(对于显示药理活性的肽的低分子量)。 构成:制备方法包括以下步骤:(1)将脂肪酸与C端,N-末端或其中间链的亲水性肽结合以制备脂肽; 和(2)重组步骤(1)的脂肽和脂质或磷脂混合物。 肽可以是具有由SEQ ID NO:1表示的序列的p26肽(preS2(120-145)),表现出药理活性的肽的表位或低分子量的作用的肽,脂肪酸 选自棕榈酸,肉豆蔻酸,硬脂酸,油酸和花生四烯酸。
