  Different Patterns of Mutagenicity of Arenediazonium Ions in V79 Cells and Salmonella typhimurium TA102: Evidence for Different Mechanisms of Action

  摘要：

  The edible mushroom Agaricus bisporus contains several arylhydrazines and arenediazonium ions that are genotoxins. The mechanism whereby arylhydrazines and arenediazonium ions are genotoxic is unknown and may be due to the arenediazonium ion itself or to aryl radicals. The reactions of four arenediazonium ions (p-X-C6H5N2+, X = -CH3, -CH2OH, -CH2OCH3, -CO2H) with purine bases, their mutagenicity, their ability to cause DNA damage, and their tendency toward free radical formation have been studied to elucidate the genotoxic species. It is suggested that either the arenediazonium or aryl radical can act as the ultimate genotoxin. Which species is dominant is dependent upon the arenediazonium ion reduction potential. This relationship may be useful in designing future studies of arenediazonium ion genotoxicity.

• Suzuki–Miyaura Cross‐Coupling of Unprotected Halopurine Nucleosides in Water—Influence of Catalyst and Cosolvent

  日期：2006.12

  Abstract Reaction conditions for the Suzuki–Miyaura cross‐coupling of unprotected halopurine nucleosides with arylboronic acids in aqueous media were investigated. A series of arylated purine nucleosides was prepared in water without an organic cosolvent, using either Pd(PPh3)4 or Pd(OAc)2/TPPTS as the catalyst.

  We report a simple and high-yielding two-step procedure for the preparation of 8-arylated guanosine mono- and triphosphates (8-aryl GXPs). The key step of our synthesis is the Suzuki–Miyaura coupling of unprotected 8-bromo GMP and 8-bromo GTP with various arylboronic acids in aqueous solution. The 8-bromoguanosine 5′-phosphates required as cross-coupling substrates were prepared from 8-bromoguanosine via an optimised Yoshikawa procedure.

  我们报告了一种简单而高产的两步法制备 8-芳基鸟苷酸单磷酸和三磷酸酯（8-芳基 GXP）。我们合成的关键步骤是在水溶液中将未受保护的 8-溴 GMP 和 8-溴 GTP 与各种芳基硼酸进行铃木-宫脲偶联。作为交叉耦合底物所需的 8-溴鸟苷 5′-磷酸酯是通过优化吉川程序从 8-溴鸟苷制备的。
