  Coumarinyl pyrazole derivatives of INH: promising antimycobacterial agents

  摘要：

  The purpose of this study was to evaluate the antimycobacterial activity of various pyrazole derivatives derived from the isoniazid pharmacophore along with coumarin scaffold. The synthesized title compounds (4a-4k) were investigated for their in vitro antimycobacterial activity against Mycobacterium tuberculosis H(37)Rv using Resazurin MIC assay. The synthesized compounds exhibited MIC ranging from 0.625 to 2.50 mu g/ml. Among the series tested, compound 3-[3-(4-fluorophenyl)-1-isonicotinoyl-1H-pyrazol-5-yl]-2H-chromen-2-one 4i was found to be the most active with MIC of 0.625 mu g/ml.
