  摘要：

  通过固相肽合成制备肽树状聚合物。单体树状聚合物首先通过组装含有交替的标准α-氨基酸和二氨基酸作为分支单元的六肽序列而获得。然后通过在核心半胱氨酸处的二硫键形成二聚体来使单体树状聚合物二聚。合成策略与功能性氨基酸和不同的二氨基酸分支单元兼容。当组氨酸残基位于最外层时，由催化三联体氨基酸组氨酸，天冬氨酸和丝氨酸组成的肽树状聚合物催化N-甲基喹啉鎓盐的水解。树状聚合物催化的7-异丁酰基-N-甲基喹啉鎓的水解遵循饱和动力学，其催化速率常数/无催化速率常数（k（cat）/ k（uncat））值为3350，催化速率常数/ Michaelis常数（k（cat）/ K（M））值是4-甲基咪唑催化反应的二级速率常数的350倍; 这相当于每个组氨酸侧链的速率提高了40倍。催化作用可归因于在树枝状聚合物表面上组氨酸残基的存在。

  New methodologies for site-specifically radiolabeling proteins with the PET isotope [18F] are required to generate high quality radiotracers for imaging in both the preclinical and clinical settings. The enzymatic radiofluorination overcomes many of the limitations encountered to date with purely chemical approaches. The bacterial enzyme lipoic acid ligase was used to conjugate [18F]-fluorooctanoic acid to both a small peptide and a Fab antibody fragment. Labeling was site-specific and highly efficient under mild aqueous conditions using small amounts of peptide/protein (1-10 nmol). The labeled construct retained full epitope binding affinity and was stable in mouse serum. Using an optimized reaction scheme, mCi quantities of [18F]-Fab were generated, an amount sufficient for human imaging.

  用PET同位素[18F]对蛋白质进行特异性标记的新方法对于在临床前和临床环境中生成高质量放射示踪剂是必需的。酶促放氟反应克服了迄今为止纯化学方法所遇到的许多限制。细菌酶硫辛酸连接酶被用于将[18F]-氟辛酸与小肽和Fab抗体片段结合。在温和水性条件下，使用少量的肽/蛋白质（1-10 nmol），标记是特异性的且高效的。标记的构建物保留了完整的抗原结合亲和力，并在小鼠血清中稳定。使用优化的反应方案，产生了足够进行人体成像的mCi数量的[18F]-Fab。
