  Novel inhibitors of bacterial protein synthesis: structure–activity relationships for 1,8-naphthyridine derivatives incorporating position 3 and 4 variants

  摘要：

  Structure-activity relationships for a recently discovered novel ribosome inhibitor (NRI) class of antibacterials were investigated. Preliminary efforts to optimize protein synthesis inhibitory activity of the series through modification of positions 3 and 4 of the naphthyridone lead template resulted in the identification of several biochemically potent analogues. A lack of corresponding whole cell antibacterial activity is thought to be a consequence of poor cellular penetration as evidenced by the enhancement of activity observed for a lead analogue tested in the presence of a cell permeabilizing agent.

  摘要：

  尝试通过标准方法合成吡啶基ze庚酮羧酸（如33）仅导致异常和意想不到的重排产物。尝试通过六元环的扩环和羟醛环的闭合来形成七元环。在每种情况下，主要产品都是由于未检测到所需产品而对原料进行了重排而产生的。最终，制备了吡啶并ze庚酮乙酯的异构体。然而，尝试皂化导致了另一种异常的重新排列。[反应：看文字]

  We describe the synthesis and antibacterial activity of a series of tetracyclic naphthyridones. The members of this series act primarily via inhibition of bacterial translation and belong to the class of novel ribosome inhibitors (NRIs). In this paper we explore the structure-activity relationships (SAR) of these compounds to measure their ability both to inhibit bacterial translation and also to inhibit the growth of bacterial cells in culture. The most active of these compounds inhibit Streptococcus pneumoniae translation at concentrations of < 5 mu M and have minimum inhibitory concentrations (MICs) of < 8 mu g/mL against clinically relevant strains of bacteria.

  products. Seven-membered ring formation was attempted by ring expansion of a six-membered ring and by aldol ring closure. In each case, the major product resulted from rearrangement of the starting material without detection of the desired product. Ultimately, an isomeric pyridoazepinone ethyl ester was prepared; however, attempted saponification resulted in another unusual rearrangement. [reaction: see
