Anthraquinone as a Redox Label for DNA: Synthesis, Enzymatic Incorporation, and Electrochemistry of Anthraquinone-Modified Nucleosides, Nucleotides, and DNA
quinone. Polymeraseincorporations of the AQ‐labeled dNTPs into DNA by primer extension with KOD XL polymerase have been successfully developed. The electrochemical properties of the AQ‐labeled nucleosides, nucleotides, and DNA were studied by cyclic and square‐wave voltammetry, which show a distinct reversible couple of peaks around −0.4 V that make the AQ a suitable redoxlabel for DNA.
Target-Selective Fluorescence Imaging and Photocytotoxicity against H<sub>2</sub>O<sub>2</sub>High-Expressing Cancer Cells Using a Photoactivatable Theranostic Agent
and photoactivatabletheranosticagent 1 consisting of 1) an arylboronic acid moiety, 2) pro‐fluorophore moiety, and 3) photoactivatable moiety (photosensitizer), selectively and effectively reacted with H2O2 while simultaneously releasing resorufin for fluorescence detection under neutral aqueous conditions. In addition, 1 was cell‐permeable, and exhibited effective photocytotoxicityagainst fluorescently
一种专门设计和合成的H 2 O 2反应性和可光活化的治疗剂1,由1)芳基硼酸部分,2)前荧光团部分和3)可光活化的部分(光敏剂)组成,可与H 2 O选择性有效地反应2,同时释放试卤灵在中性水性条件下进行荧光检测。此外,有1种具有细胞渗透性,仅在光照射后才对荧光可视化细胞表现出有效的光细胞毒性。结果还表明1产生了对H 2 O 2的选择性荧光响应,甚至在活的培养细胞中也是如此。
