• Probe for imaging PARP-1 activity

  Provided are embodiments of a small molecule tracer for positron emission tomography (PET) imaging of the enzyme activity of PARP-1 that is responsible for DNA-damage sensing and critically involved in radiation therapy and some chemotherapy response mechanisms. These PARP-1 tracers are derivatives of nicotinamide adenine dinucleotide (NAD), which is the natural substrate for PARP-1. Provided are NAD derivatives that include a linker moiety to which may be attached a label moiety such as a PET detectable fluorine to generate a 6N-(triazo-PEG2-18F)-NAD. Especially advantageous for use in PET and MRI scanning detection systems is the attachment of a chelating agent that allows for the formation of a chelator-metal ion complex.

  本发明提供了一种小分子示踪剂的实施方案，用于对 PARP-1 的酶活性进行正电子发射断层扫描（PET）成像，PARP-1 负责 DNA 损伤感应，并严重参与放射治疗和某些化疗反应机制。这些 PARP-1 示踪剂是烟酰胺腺嘌呤二核苷酸（NAD）的衍生物，NAD 是 PARP-1 的天然底物。所提供的 NAD 衍生物包括一个连接基团，该连接基团可连接一个标签基团，如 PET 可检测的氟，从而生成 6N-(三氮杂-PEG2-18F)-NAD。在 PET 和 MRI 扫描检测系统中使用时，特别有利的是附加螯合剂，以形成螯合剂-金属离子复合物。

• Chemoselective Perfluoromethylation of Thio- and Selenoamides
  作者：Xianhong Xu、Jianyu Zhang、Tao Xu

  日期：2020.11.6

  A chemo- and regioselective perfluoromethylation using thioamides/selenoamides (prepared one step from corresponding lactams) as starting materials has been discovered. The reaction demonstrated complementary chemoselectivity to the C-H trifluoromethylation of (hetero)arenes as well as remarkable functional group compatibility especially toward radical sensitive olefin-, alkyne-, and arylhalide-bearing substrates. The examples of perfluorothio-/selenolated drug molecules indicated application potential of this strategy in drug modification and drug-analogue preparation.
