  Synthesis and antimycobacterial evaluation of newer 1-cyclopropyl-1,4-dihydro-6-fluoro-7-(substituted secondary amino)-8-methoxy-5-(sub)-4-oxoquinoline-3-carboxylic acids

  摘要：

  Thirty-four newer 1-cyclopropyl-1,4-dihydro-6-fluoro-7-(substituted secondary amino)-8-methoxy-5-(sub)-4-oxoquinoline-3-carboxylic acids were synthesized from 1,2,3,4-tetrafluoro benzene and evaluated for in vitro and in vivo antimycobacterial activities against Mycobacterium tuberculosis H37Rv (MT13), multi-drug resistant M. tuberculosis (MDR-TB) and Mycobacterium sinegmatis (MC2) and also tested for the ability to inhibit the supercoiling activity of DNA gyrase. Among the synthesized compounds, 7-(1-(4-methoxybenzyl)-3,4,5,6,7,8-hexahydroisoquinolin-2(1H)-yl)-1-cyclopropy1-6-fluoro-1,4-dihydro-8-methoxy-5-nitro-4-oxoquinoline-3-carboxylic acid (13n) was found to be the most active compound in vitro with MIC of 0.16 and 0.33 mu M against MT13 and MDR-TB, respectively. In the in vivo animal model 13n decreased the bacterial load in lung and spleen tissues with 2.54 and 2.92 - log 10 protections, respectively, at the dose of 50 mg/kg body weight. Compound 13n also inhibited the supercoiling activity of mycobacterial DNA gyrase with IC50 of 30.0 mu g/ml. (C) 2007 Elsevier Ltd. All rights reserved.
