  Design, Synthesis, and Efficacy Testing of Nitroethylene- and 7-Nitrobenzoxadiazol-Based Flavodoxin Inhibitors against Helicobacter pylori Drug-Resistant Clinical Strains and in Helicobacter pylori-Infected Mice

  摘要：

  Helicobacter pylori (Hp) infection is the main cause of peptic ulcer and gastric cancer. Hp eradication rates have fallen due to increasing bacterial resistance to currently used broad-spectrum antimicrobials. We have designed, synthesized, and tested redox variants of nitroethylene- and 7-nitrobenzoxadiazole-based inhibitors of the essential Hp protein flavodoxin. Derivatives of the 7-nitrobenzoxadiazole lead, carrying reduced forms of the nitro group and/or oxidized forms of a sulfur atom, display high therapeutic indexes against several reference Hp strains. These inhibitors are effective against metronidazole-, clarithromycin-, and rifampicin-resistant Hp clinical isolates. Their toxicity for mice after oral administration is low, and, when administered individually at single daily doses for 8 days in a mice model of Hp infection, they decrease significantly Hp gastric colonization rates and are able to eradicate the infection in up to 60% of the mice. These flavodoxin inhibitors constitute a novel family of Hp-specific antimicrobials that may help fight the constant increase of Hp antimicrobial-resistant strains.

  邻萘醌催化剂的基质混杂性：脱氧性交叉偶联和N-亚硝化的催化好氧胺氧化方案。

  摘要：

  基于邻萘醌的有机催化剂已被鉴定为通用的好氧氧化催化剂。伯胺很容易通过脱氨途径与伯硝基烷烃交联，从而以良好或优异的收率得到硝基烯烃衍生物。仲胺和叔胺对邻萘醌催化剂是惰性的。然而，仲硝基烷烃很容易通过邻萘醌催化剂转化为相应的亚硝酸盐类，后者将胺原位氧化为相应的N。-亚硝基化合物。在不以化学计量的量使用刺激性氧化剂的情况下，本催化好氧氧化方案利用底物的混杂特性在温和的反应条件下提供了容易的胺氧化产物的通道。
