  Design, Synthesis, and Biological Characterization of a Caspase 3/7 Selective Isatin Labeled with 2-[¹⁸F]fluoroethylazide

  摘要：

  Imaging of programmed cell death (apoptosis) is important in the assessment of therapeutic response in oncology and for diagnosis in cardiac and neurodegenerative disorders. The executioner caspases 3 and 7 ultimately effect cellular death, thus providing selective molecular targets for in vivo quantification of apoptosis. To realize this potential, we aimed to develop F-18-labeled isatin sulfonamides with high metabolic,stability and moderate lipophilicity while retaining selectivity and affinity for caspase 3/7. A small library of isatins modified with fluorinated aromatic groups and heterocycles was synthesized. A lead compound incorporating 2'-fluoroethyl-1,2,3-triazole was identified with subnanomolar affinity for caspase 3. "Click labeling" provided the F-18-labeled tracer in 65 +/- 6% decay-corrected radiochemical yield from 2-[F-18]fluoroethylazide. The compound showed high stability in vivo with rapid uptake and elimination in healthy tissues and tumor. The novel F-18-labeled isatin is a candidate radiotracer for further preclinical evaluation for imaging of apoptosis.

  有机锗烷的正交 C-O 键结构

  摘要：

  我们报告了一种完全正交的 C-O 键形成策略，该策略涉及芳基锗烷与烷基醇（伯醇、仲醇和叔醇）以及羧酸的选择性偶联，耐受其他广泛使用的偶联处理，例如芳香族（伪）卤素（ C–I、C–Br、C–Cl、C–F、C–OTf、C–OFs)、硅烷和硼酸衍生物。这种前所未有的基于 [Ge] 的 C-O 键结构快速（15 分钟到几个小时的反应时间）、耐空气性、操作简单且温和，因为它是无碱的并且在室温下进行。

  involves the selective coupling of arylgermanes with alkyl alcohols (primary, secondary and tertiary) as well as carboxylic acids, tolerating otherwise widely employed coupling handles, such as aromatic (pseudo)halogens (C–I, C–Br, C–Cl, C–F, C–OTf, C–OFs), silanes and boronic acid derivatives. This unprecedented [Ge]-based C–O bond construction is rapid (15 min to few hours reaction time), air-tolerant
