The present invention relates to the preparation of a hydrophobic medicinal auxiliary material and a drug-loaded fat emulsion, and in particular to a hydrophobic auxiliary material with the structural formula as shown below, wherein R is a hydrophobic natural compound or hydrophobic synthetic compound with one to three hydroxyl groups (n = 1-3); R1 is an α -amino protecting group, and R2 is an amino acid side chain, when m = 0, R reacts with an amino acid derivative with a protecting group by means of esterification to form a hydrophobic auxiliary material carrying the amino acid derivative with a protecting group; or when m = 1, R first introduces an amino acid linking arm of different chain lengths (1 = 1, 2, 4, 6) by means of an ester group, and then introduces an amino acid derivative with a protecting group to form a hydrophobic auxiliary material carrying an amino acid derivative polypeptide with a protecting group. The introduction of an amino acid derivative with an aromatic or alkoxycarbonyl or acyl amino protecting group on the hydrophobic auxiliary material is conducive to increasing the solubility of the drug in the hydrophobic auxiliary material, and improving the stability of the drug-loaded fat emulsion.
本发明涉及一种疏水性药用辅助材料和载药脂肪乳剂的制备方法,特别是涉及一种结构式如下的疏水性辅助材料,其中R为具有1-3个羟基(n=1-3)的疏水性天然化合物或疏水性合成化合物;当 m = 0 时,R 通过酯化反应与带有保护基的氨基酸衍生物反应,形成带有保护基的氨基酸衍生物的疏水辅助材料;或当 m = 1 时,R 首先通过酯基引入不同链长(1 = 1、2、4、6)的氨基酸连接臂,然后引入带保护基的氨基酸衍生物,形成携带带保护基的氨基酸衍生物多肽的疏水性辅助材料。在疏水辅助材料上引入带有芳香族或烷氧基羰基或酰氨基保护基团的氨基酸衍生物,有利于增加药物在疏水辅助材料中的溶解度,提高载药脂肪乳剂的稳定性。
