title: Discovery of novel phenoxyacetic acid derivatives as antimycobacterial agents.
abstract: A series of 2-{4-[1-amino (thioxo) methyl-5-(substituted phenyl)-4,5-dihydro-1H-3-pyrazolyl]-2-methoxyphenoxy}acetic acid and 2-{4-[1-carbamoyl-5-(substituted phenyl)-4,5-dihydro-1H-3-pyrazolyl]-2-methoxyphenoxy}acetic acid were synthesized and the in vitro activity of the synthesized compounds against Mycobacterium tuberculosis H37Rv (MTB) and INH-resistant M. tuberculosis (INHR-MTB) was studied. Among the synthesized compounds, compound (3f) 2{-[4-(1-carbamoyl-5-(chlorophenyl)-4,5-dihydro-1H-3-pyrazolyl]-2-methoxyphenoxy}acetic acid was found to be the most active against M. tuberculosis H37Rv (MTB) and INH-resistant M. tuberculosis (INHR-MTB) with minimum inhibitory concentration of 0.06 microg/ml.
