  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。

  The present invention is related to a compound that includes a lysosomal enzyme and a targeting moiety, for example, a compound that includes iduronate-2-sulfatase conjugated to Angiopep-2 through a linker formed by specific click chemistry reactions. In certain embodiments, these compounds, owing to the presence of the targeting moiety, can cross the blood-brain barrier or accumulate in the lysosome more effectively than the enzyme alone. The invention also features pharmaceutical compositions containing such compounds and methods for treating lysosomal storage disorders (e.g., mucopolysaccharidosis Type II) using such compounds.

  本发明涉及一种化合物，包括溶酶体酶和靶向基团，例如，包括通过特定点击化学反应形成的连接物将硫酸二糖醛酸酶与Angiopep-2结合在一起的化合物。在某些实施例中，由于存在靶向基团，这些化合物可以比单独的酶更有效地穿过血脑屏障或在溶酶体中积累。该发明还涉及含有这种化合物的药物组合物以及使用这种化合物治疗溶酶体贮积疾病（例如，粘多糖贮积症II型）的方法。
