We report in vitro antimycobacterial properties of ring-substituted quinolines (series 1-4) constituting 56 analogues against drug-sensitive and drug-resistant If. tuberculosis H37Rv strains. The most effective compounds 2h (R-1 = R-2 = c-C6H11, R-3 = NO2, series 1) and 13g (R-1 = OC7H15, R-2 = NO2, series 4) have exhibited an MIC value of 1 mug/mL against drug-sensitive If. tuberculosis H37Rv strain that is comparable to first lisle anti-tuberculosis drug, isoniazid. :Selected analogues (2d, 2g 2h, 4e, 6b, 13b, 13g, and 14e, MIC: less than or equal to6.25 mug/mL) upon further evaluation against single-drug-resistant (SDR) strains of M. tuberculosis H37Rv 9 have produced potent efficacy in the range between 6.25 and 50 mug/mL.
