  • Schizophyllans carrying oligosaccharide appendages as potential candidates for cell-targeted antisense carrier

    Schizophyllans carrying β-lactoside and α-mannoside appendages were prepared from native schizophyllan through NaIO4 oxidation followed by reductive amination using aminoethyl-β-lactoside and α-mannoside, respectively. The resulting schizophyllans form stable macromolecular complexes with polynucleotides, such as poly(C) and poly(dA). Specific affinity between these macromolecular complexes and saccharide-binding proteins was demonstrated by surface plasmon resonance and agarose gel staining assays. β-Lactoside-appended schizophyllan enhanced an antisense activity in hepatocytes which express lactoside-binding proteins on their cell surfaces.
    通过NaIO4氧化原生裂褶菌多糖,随后分别使用基乙基-β-半乳糖苷和α-甘露糖苷进行还原胺化反应,制备了带有β-半乳糖苷和α-甘露糖苷侧链的裂褶菌多糖。由此得到的裂褶菌多糖能与多聚核苷酸(如聚胞苷酸和聚dA)形成稳定的巨分子复合物。通过表面等离子体共振和琼脂糖凝胶染色实验,证明了这些巨分子复合物与糖结合蛋白之间存在特定的亲和力。带有β-半乳糖苷侧链的裂褶菌多糖增强了表达细胞表面半乳糖苷结合蛋白的肝细胞中的反义活性。

    A new biotinylated lactose derivative bearing a nitro-substituted chromogenic diazirine was synthesized. The biotinyl group within the structure enabled the performance of a convenient assay of GM3 synthase based on avidin-biotin technology, and the Km values of this biotinylated photoprobe were determined as 40 and 47 μM using bovine brain and rat liver Golgi as enzyme sourced, respectively. Furthermore, the sialylation of lactosylceramide, a natural acceptor substrate for GM3 synthase, was completitively inhibited by this synthetic analog. The reagent could be a useful chromogenic photoprobe for GM3 synthase.

    metalloproteinases (MMPs), especially MMP-13. The design of heterobifunctional inhibitors that can block galectin binding and MMPs both directly and by preventing their galectin-dependent induction selectively offers a perspective to dissect the roles of lectins and proteolytic enzymes. We describe the synthesis of such a reagent with a bivalent galectin ligand connected to an MMP inhibitor and of two tetravalent
    聚糖与组织凝集素配对可控制(病理)生理学中的多种效应途径。一个临床相关的例子是半乳糖凝集素-1和-3(Gal-1和-3)通过基质蛋白酶(MMP),特别是MMP-13在骨关节炎(OA)进展中的促降解活性。异双功能抑制剂的设计可以直接阻断半乳糖凝集素和基质蛋白酶的结合,也可以选择性地阻止其半乳糖凝集素依赖性诱导,这为剖析凝集素和蛋白解酶的作用提供了一个视角。我们描述了这种试剂的合成,其具有连接到 MMP 抑制剂的二价半乳糖配体和两个四价糖簇,其头基呈现发生细微变化,以进一步阐明对配体结合的影响。使用固定组织切片对含有体内半乳糖凝集素混合物的临床材料进行测试。优化实验参数后,双色荧光显微镜监测与细胞糖组的结合。在存在抑制剂的情况下,半乳糖凝集素与 OA 样本的结合显着减少。这些结果开启了使用已知半乳糖凝集素和 MMP 对疾病进展影响的临床材料切片来检查定制二位化合物对混合物中凝集素结合的抑制能力的视角。
