  来自三氮烯基前体的放射性标记生物素酰胺：合成、结合和体内特性

  摘要：

  N-(4-[127/125/123l]碘苄基)生物素酰胺4a-4c的合成通过N-[4-(3',3'-二甲基三氮烯基)苄基)生物素酰胺与碘化钠的直接分解进行描述了 CF3COOH 的存在。以这种方式碘化的生物素与抗生物素蛋白 (Kd = 2.84 ± 0.45 × 10−15 M, n = 3.9 ± 0.6) 形成稳定的复合物，其在过量天然生物素存在下以 0.034 ± 0.006 hr1 的速率常数解离。血液清除研究和甲状腺摄取不足表明该化合物在体内未脱碘，并且在循环中的表现与天然生物素非常相似。这种芳基三氮烯前体方法适用于用短寿命放射性卤化物进行标记。它可用于生产无载体添加的生物素衍生物，用于涉及抗生物素蛋白或链霉抗生物素蛋白的生物学研究和测定。

  Design and Synthesis of Biotin Chain-Terminated Glycopolymers for Surface Glycoengineering

  摘要：

  Biotin chain-terminated glycopolymers were generated by cyanoxyl-mediated free-radical polymerization using a biotin-derivatized arylamine initiator with high conversion (75%) and low polydispersity (1.30). Streptavidin-biotinylated glycopolymer binding was verified by SDS-PAGE gel shift assay and patterned glycocalyx-mimetic surfaces successfully fabricated.

  Polymeric molecules including glycopolymers useful for biomolecular recognition processes are provided comprising anchoring groups by which they can be immobilized onto surfaces. These molecules are easily synthesized. They are broadly described as molecules comprising a polymer backbone with pendent multivalent groups attached to the polymer backbone and an anchoring group attached to the polymer backbone for covalently or noncovalently attaching the molecule to a surface or another molecule. Such polymeric molecules can be attached to other molecules or surfaces to provide a wide range of bioactive materials. In addition, this invention provides sulfated glycopolymers which are useful for reducing blood coagulation, stimulating growth factors to bind to their receptors, stimulating cell proliferation and preventing degradation of soluble growth factors under conditions of low pH, heat, and proteolytic enzymes.
