  7-Azetidinylquinolones as antibacterial agents. Synthesis and structure-activity relationships

  摘要：

  A series of novel antibacterial quinolones and naphthyridones has been prepared which contain 7-azetidinyl substituents in place of the usual piperazine or aminopyrrolidine groups. These azetidinyl derivatives were evaluated for in vitro activity by determining minimum inhibitory concentrations against a variety of bacteria. In vivo efficacy in the mouse infection model and blood levels in the mouse were determined for several compounds. The influence on the structure-activity relationships of varying substituents in the azetidine ring and at position 8 (CH, CF, CCl, N) and N-1 (ethyl, fluoroethyl, cyclopropyl, tert-butyl, 4-fluorophenyl, and 2,4-difluorophenyl) was also studied. Compounds with outstandingly broad-spectrum activity, particularly against Gram-positive organisms, improved in vivo efficacy, and high blood levels were identified in this work. 7-Azetidinyl-8-chloroquinolones were considered as warranting further development.

  摘要：

  各种7-（3-取代的氮杂环丁烷-1-基）-1-环丙基-6,8-二氟-1,4-二氢4-氧代喹啉-3-羧酸的定量构效关系（QSAR），研究了14-25，以阐明3-取代的氮杂环丁烷增强抗菌活性的结构要求。在针对五个代表性革兰氏阴性细菌的相对平均抗菌活性指数GNM与这些分子的计算疏水参数CLOG P之间似乎存在良好的抛物线关系。最有效的导数的CLOG P值预计约为2.3。另一方面，相对于五个代表性的革兰氏阳性细菌，相对于平均抗菌活性指数GPM仍然很高，并且相当恒定，而与氮杂环丁烷部分的结构变化无关。为了证实这些发现，QSAR分析成功地扩展到了喹诺酮羧酸26-34，它带有各种取代的吡咯烷，哌嗪和哌啶衍生物，而不是氮杂环丁烷。结果表明，将任何酰胺取代基引入这些杂环胺部分将导致GNM显着降低，而在远离N-1位置的两个或三个碳原子处引入一些氨基取代基会大大增强GNM。由于氮杂环丁烷喹诺酮类药物在体内的抗菌
