  喹啉-2-羧酸盐、新德里金属-β-内酰胺酶-1 锌结合抑制剂对碳青霉烯类多药耐药细菌的动力学、热力学和结构效应

  摘要：

  由金属-β-内酰胺酶（MBL）如新德里金属-β-内酰胺酶-1（NDM-1）介导的碳青霉烯类耐药性已成为威胁必需β-内酰胺抗生素疗效的主要因素。从命中片段吡啶二羧酸 (DPA) 开始，8-羟基-和 8-磺酰胺基-喹啉-2-羧酸被开发为 NDM-1 抑制剂，具有高度改进的抑制活性和结合亲和力。天然蛋白质质谱和生物层干涉测量法证明，最活跃的化合物与两个锌离子形成可逆非活性三元蛋白质抑制剂复合物。通过等温滴定量热法和同位素标记蛋白质的核磁共振波谱显示 NDM-1 结构的修饰具有显着的熵增益。最好的化合物是 NDM-1 和其他代表性 MBL 的有效抑制剂，对人类锌结合酶没有或很少有抑制作用。这些抑制剂显着降低了美罗培南对重组表达bla NDM-1 的多重耐药细菌以及几种多重耐药临床菌株的最低抑菌浓度 (MIC)，其浓度对人体细胞无毒。

  Nonreductive Deiodination of ortho-Iodo-Hydroxylated Arenes Using Tertiary Amines

  摘要：

  [GRAPHIC]A convenient and nonreductive deiodination is reported for the ortho-iodo-hydroxylated arenes inch, ding derivatives of quinolinol, phenol, and naphthol. Tertiary amines pyridine, triethylamine, and N-methylmorpholine in the presence of water initiated deiodination of ortho-iodo-hydroxylated arenes without affecting para-iodine and other reduction-susceptible groups. This reported method also works efficiently for polyiodinated systems. Simplicity, short reaction times, and absence of reducing catalyst are features of this method.

  at the same time, blue-shifted of fluorescence emission wavelength was observed when the C-5 position of 8-hydroxyquinoline was substituted by electron-withdrawing group. When the C-4 position of 8-hydroxyquinolie was substituted by methyl or the C-5 position was substituted by sulfonic acid group, the corresponding zinc complexes had higher fluorescence intensity than 8-hydroxyquinolie zinc.

  A one-step transformation of heterocyclic N-oxides to 2-alkyl-, aryl-, and alkenyl-substituted N-heterocycles is described. The success of this broad-scope methodology hinges on the combination of copper catalysis and activation by lithium fluoride or magnesium chloride. The utility of this method for the late-stage modification of complex N-heterocycles is exemplified by facile syntheses of new structural
