title: Preliminary evaluation of in-vitro antimycobacterial properties of N1-(aryliden)-2-pyridinecarboxyamidrazones.
abstract: After preliminary in vitro screening of 17 newly synthesized compounds belonging to the chemical class of N1-(aryliden)-2-pyridinecarboxyamidrazones, active against Mycobacterium tuberculosis H37Rv, the minimum inhibitory concentrations (MICs) of the ten most promising agents against three clinical isolates were determined by agar dilution. Compounds 12 and 14 were the most active, each inhibiting strain H37Rv at concentrations of 8 microg/ml and having a MIC of 16 microg/ml against the human isolates. The results obtained in this preliminary study confirmed the interesting antitubercular properties of these newly synthesized compounds and allowed us to carry out our investigations over a large number of isolated clinical strains.
