  N-Acetylgalactosamino Dendrons as Clearing Agents to Enhance Liver Targeting of Model Antibody-Fusion Protein

  摘要：

  Dendrimer clearing agents represent a unique class of compounds for use in multistep targeting (MST) in radioimmunotherapy and imaging. These compounds were developed to facilitate the removal of excess tumor-targeting monoclonal antibody (mAb) prior to administration of the radionuclide to minimize exposure of normal tissue to radiation. Clearing agents are designed to capture the circulating mAb, and target it to the liver for metabolism. Glycodendrons are ideally suited for MST applications as these highly branched compounds are chemically well-defined, thus advantageous over heterogeneous macromolecules. Previous studies have described glycodendron 3 as a clearing agent for use in three-step MST protocols, and early in vivo assessment of 3 showed promise. However, synthetic challenges have hampered its availability for further development. In this report we describe a new sequence of chemical steps which enables the straightforward synthesis and analytical characterization of this class of dendrons. With accessibility and analytical identification solved, we sought to evaluate both lower and higher generation dendrons for hepatocyte targeting as well as clearance of a model protein. We prepared a series of clearing agents where a single biotin is connected to glycodendrons displaying four, eight, sixteen or thirty-two alpha-thio-N-acetylgalactosamine (alpha-SGalNAc) units, resulting in compounds with molecular weights ranging from 2 to 17 kDa, respectively. These compounds were fully characterized by LCMS and NMR. We then evaluated the capacity of these agents to clear a model I-131-labeled single chain variable fragment antibody-streptavidin (I-131-scFv-SAv) fusion protein from blood and tissue in mice, and compared their clearing efficiencies to that of a 500 kDa dextran-biotin conjugate. Glycodendrons and dextran-biotin exhibited enhanced blood clearance of the scFv-SAv construct. Biodistribution analysis showed liver targeting/uptake of the scFv-SAv construct to be 2-fold higher for compounds 1 to 4, as well as for the 500 kDa dextran, over saline. Additionally, the data suggest the glycodendrons clear through the liver, whereas the dextran through reticuloendothelial system (RES) metabolism.

  酰胺基烷基吲哚作为有力和选择性的多发性硬化症小鼠模型体内功效的选择性大麻素2型受体激动剂。

  摘要：

  选择性CB 2激动剂代表了一种有吸引力的治疗策略，可用于治疗各种疾病，而无需CB 1受体介导的精神病副作用。我们对黑市设计师药物SDB-001进行了合理的优化，从而确定了有效的和选择性的CB 2激动剂。3-氨基烷基吲哚处的7-甲氧基或7-甲硫基取代产生有效的CB 2拮抗剂（27或28，IC 50 = 16-28 nM）。从吲哚环的3位到2位取代酰胺基烷基大大提高了CB 2上的激动剂选择性，而不是CB 1上受体。特别是，化合物57对CB 2受体表现出有效的激动剂活性（EC 50 = 114–142 nM），而对CB 1受体没有明显的激动剂或拮抗剂活性。此外，在多发性硬化症的实验性自身免疫性脑脊髓炎（EAE）小鼠模型中，有57个显着减轻了临床症状并保护了小鼠中枢神经系统免受免疫损伤。
