  Synthesis and antibacterial evaluation of a novel tricyclic oxaborole-fused fluoroquinolone

  摘要：

  We have designed and synthesized a novel class of compounds based on fluoroquinolone antibacterial prototype. The design concept involved the replacement of the 3-carboxylic acid in ciprofloxacin with an oxaborole-fused ring as an acid-mimicking group. The synthetic method employed in this work provides a good example of incorporating boron atom in complex molecules with multiple functional groups. The antibacterial activity of the newly synthesized compounds has been evaluated. (C) 2012 Elsevier Ltd. All rights reserved.
