    Novel Galactosylated Poly(ethylene glycol)-Cholesterol for Liposomes as a Drug Carrier for Hepatocyte-Targeting
    摘要:
    在这项研究中,合成了三种类型的半乳糖化胆固醇(即gal-PEG194-chol、gal-PEG1000-chol和gal-PEG2000-chol),它们的一个端基通过不同链长的聚乙二醇与半乳糖基团连接,另一个端基与胆固醇连接。通过薄膜水化法制备了半乳糖修饰的脂质体,并利用硫酸铵梯度法将阿霉素(DOX)装载到脂质体中。对含有半乳糖化胆固醇的脂质体进行了表征。流式细胞术和激光共聚焦扫描显微镜分析显示,半乳糖修饰的脂质体通过脱唾液酸糖蛋白受体(ASGP-R)介导的内吞作用促进了脂质体进入HepG2细胞的细胞内摄取。细胞毒性测定表明,半乳糖修饰脂质体的细胞增殖抑制效果高于未修饰脂质体。此外,对肝脏冷冻切片的研究表明,半乳糖修饰的脂质体增强了脂质体进入肝细胞的细胞内摄取。综上所述,这些结果表明,含有这种半乳糖化胆固醇(即gal-PEG-chol)的脂质体,作为肝细胞选择性靶向药物传递载体具有巨大的潜力。

    The invention relates to conjugates in which a sterol is functionalized by an ether bond with a water-soluble polymer to which a guiding ligand is bound. These conjugates improve the physico-chemical and delivery properties of their carrying vesicles, making these more stable, homogeneous and effective. A method for their preparation, a pharmaceutical composition containing said liposomes, and their therapeutic use are described as well.

    wide-angle X-ray diffraction (WAXD) technique. Analysis of the wide-angle X-ray diffraction data reveals that this class of molecules adopts a hexagonal columnar organization in the gel and in the solid state. Each slice of these hexagonal columnar structures is composed of a dimeric molecular-assembly as a building block. Significant changes in the conformation of the oxyethylene chains could be triggered
    合成了一系列新的2,4,6-三氯-嘧啶-5-甲醛的亲脂性胆固醇基衍生物。为了了解它们对这些化合物自组装的影响,在氢键促进嘧啶核心和胆固醇尾基之间插入了可变长度的氧乙烯间隔基。只有具有最短间隔基的化合物1a在有机溶剂(例如正丁醇和正十二烷)中形成凝胶。而其他具有较长间隔基的成员(1b和c)则导致正丁醇和n中的溶胶形成和沉淀-十二烷。使用依赖于温度的UV-Vis和CD光谱研究了与胶凝过程相关的自组装现象。通过扫描电子显微镜(SEM)和原子力显微镜(AFM)检查了从不同有机溶剂获得的冻干凝胶的形态特征。使用偏振光学显微镜(POM)和差示扫描量热法(DSC)探索了这些分子及其相关的碱金属离子配合物的固相行为。使用广角X射线衍射(WAXD)技术进一步探查了干凝胶和固态分子的排列方式。对广角X射线衍射数据的分析表明,这类分子在凝胶和固态时采用六边形柱状组织。这些六边形柱状结构的每个切片均由二聚体分子组

    In this study, three types of galactosylated cholesterol (i.e., gal-PEG194-chol, gal-PEG1000-chol and gal-PEG2000-chol) were synthesized with one terminal of polyethylene glycol of various chain lengths conjugated to the galactoside moiety, and the other terminal conjugated to the cholesterol. The galactose-modified liposomes were prepared by thin film-hydration method and doxorubicin (DOX) was loaded to the liposomes by using a ammonium sulfate gradient procedure. The liposomal formulations with galactosylated cholesterol were characterized. Flow cytometry and laser confocal scanning microscopy analyses showed that the galactose-modified liposomes facilitated the intracellular uptake of liposomes into HepG2 via asialoglycoprotein receptor (ASGP-R) mediated endocytosis. Cytotoxicity assay showed that the cell proliferation inhibition effect of galactose-modified liposomes was higher than that of the unmodified liposomes. Additionally, the study on frozen section of liver showed that the galactose-modified liposomes enhanced the intracellular uptake of liposomes into hepatocytes. Taken together, these results suggested that liposomes containing such galactosylated cholesterol (i.e., gal-PEG-chol), had a great potential as drug delivery carriers for hepatocyte-selective targeting.

    A straightforward synthesis of 2′-functionalized uridines was developed based on a Cu-catalyzed cycloaddition of 2′-azido-2′-deoxyuridine and functionalized alkynes. The functions comprise biochemically important groups such as lipids, a fluorescent marker (Cy5 analogue), pentaacetylglucose, lysine and biotin, and are linked to the 2′-position of uridine by a 1,2,3-triazole ring.
