Abstract

The lysozyme (LZ)-entrapped mannosylated liposomes were prepared in this study by the use of N-octadecyl-D-mannopyranosylamine (SAMAN), which had been synthesized in-house and confirmed by characterization with FTIR and NMR. The reactant residues of synthesized SAMAN were found to be less than 1%. The mean sizes, zeta potentials, drug entrapment efficiencies, and loading capacities of all liposomal formulations were in the ranges of 234.7 to 431.0 nm, -10.97 to -25.80 mV, 7.52 to 14.10%, and 1.44 to 2.77%, respectively. The permeability of mannosylated LZ liposomes across Caco-2 cell monolayers was significantly enhanced to about 2.5- and 7-folds over those of conventional liposomes and solution, respectively, which might be due to the role of mannose receptor or mannose-binding protein on the intestinal enterocytes.

摘要

本研究通过使用 N-十八烷基-D-甘露吡喃胺(SAMAN)制备了溶菌酶(LZ)包封的甘露糖化脂质体,SAMAN 是在内部合成的,并通过傅里叶变换红外光谱和核磁共振进行了表征确认。合成的 SAMAN 的反应物残留量被发现小于 1%。所有脂质体制剂的平均粒径、ζ电位、药物包封效率和载药量分别在 234.7 至 431.0nm、-10.97 至-25.80mV、7.52 至 14.10%和 1.44 至 2.77%之间。甘露糖化 LZ 脂质体穿过 Caco-2 细胞单层的通透性显著提高,相对于普通脂质体和溶液分别提高了约 2.5 倍和 7 倍,这可能是由于肠上皮细胞上甘露糖受体或甘露糖结合蛋白的作用。
