  Novel pyrazole derivatives as potent inhibitors of type II topoisomerases. Part 1: Synthesis and preliminary SAR analysis

  摘要：

  In an attempt to search for a new class of antibacterial agents, we have discovered a series of pyrazole analogs that possess good antibacterial activity for Gram-positive and Gram-negative organisms via inhibition of type II bacterial topoisomerases. We have investigated the structure-activity relationships of this series, with an emphasis on the length and conformation of the linker. This work led to the identification of tetrahydroindazole analogs, such as compound 1, as the most potent class of compounds. (c) 2007 Elsevier Ltd. All rights reserved.

  A series of Novel Bacterial Topoisomerase Inhibitors (NBTIs) employing a linker derived from isomannide were synthesized and evaluated. Reduced hERG inhibition was observed compared to structure-matched analogues with different linkers, and compound 6 showed minimal proarrhythmic potential using an in vitro panel of cardiac ion channels. Compound 6 also displayed excellent activity against fluoroquinolone-resistant
