We synthesized various glycolipid derivatives and examined the in vivo behaviors of liposomes modified with these movel glycolipid derivatives. Gal-t-pas (1, 8-(2-hexadecyloctadecanoylamino)-3, 6-dioxaoctyl}-β-D-galactoside), Lac-t-psa (3, 8-(2-hexadecyloctadecanoylamino)-3, 6-dioxaoctyl β-D-lactoside) and GalNAc-t-psa (4, 8-(2-hexadecyloctadecanoylamino)-3, 6-dioxaoctyl 2-acetamido-β-D-galactopyranoside) modified liposomes were recognized by the liver. Lac-t-psa (3) modified liposome was accumulated to the highest degree, followed by GalNAc-t-psa (4) modified liposome and then Gal-t-psa (1) modified liposome. The intrahepatic distributions of Gal-t-psa (1), GalNAc-t-psa (4), Glc-t-psa (2, 8-(2-hexadecyloctadecanoylamido)-3, 6-dioxaoctylβ-D-glucopyranoside) and Lac-t-psa (3) modified liposomes were investigated. GalNAc-t-psa (4) and Lac-t-psa (3) modified liposome were accumulated to greater extents than Gal-t-psa (1) modified liposome in hepatic parenchymal cells. The intrahepatic distribution of these liposomes showed that Lac-t-psa (3) and GalNAc-t-psa (4) were preferable to Gal-t-psa (1) for the selective delivery of liposomes to hepatic parenchymal cells.
我们合成了多种甘油脂衍生物,并检查了用这些新型甘油脂衍生物修饰的脂质体在体内的行为。Gal-t-pas (1, 8-(2-十六烷基十八酸酰胺)-3, 6-二氧八烯}-β-D-半乳糖苷)、Lac-t-psa (3, 8-(2-十六烷基十八酸酰胺)-3, 6-二氧八烯 β-D-乳糖苷) 和 GalNAc-t-psa (4, 8-(2-十六烷基十八酸酰胺)-3, 6-二氧八烯 2-乙酰氨基-β-D-半乳糖吡喃糖苷) 修饰的脂质体被肝脏识别。Lac-t-psa (3) 修饰的脂质体积累程度最高,其次是 GalNAc-t-psa (4) 修饰的脂质体,最后是 Gal-t-psa (1) 修饰的脂质体。我们研究了 Gal-t-psa (1)、GalNAc-t-psa (4)、Glc-t-psa (2, 8-(2-十六烷基十八酸酰胺)-3, 6-二氧八烯 β-D-葡萄糖吡喃糖苷) 和 Lac-t-psa (3) 修饰脂质体在肝脏内的分布情况。GalNAc-t-psa (4) 和 Lac-t-psa (3) 修饰的脂质体在肝实质细胞中的积累程度大于 Gal-t-psa (1) 修饰的脂质体。这些脂质体的肝内分布显示,Lac-t-psa (3) 和 GalNAc-t-psa (4) 在选择性地将脂质体输送至肝实质细胞方面比 Gal-t-psa (1) 更为理想。
