Abstract
Infections caused by non-tuberculous mycobacteria and multidrug-resistant Mycobacterium tuberculosis are difficult to treat, and so new compounds potentially active against these bacteria are being sought. A series of 2-pyridinecarboxamidrazone derivatives, recently synthesized, have been evaluated for their inhibitory activity against 17 Mycobacterium avium isolates; the agar dilution method showed different degrees of susceptibility to the new molecules. Four molecules, three of which are chlorine derivatives, inhibited 94% of the strains tested with an MIC of 32 mg/L. These data indicate that these new pyridine-2-carboxamidrazones merit further study as antimycobacterial agents.

Abstract
After preliminary in vitro screening of 15 newly synthesized compounds belonging to the chemical class of N1-(aryliden)-4-pyridinecarboxyamidrazones against Mycobacterium tuberculosis reference strain H37 Rv, we determined the minimum inhibitory concentrations (MICs) of the six most promising chemicals against different species of Mycobacterium and different strains of M. tuberculosis. The agar dilution method was employed against M. gordonae, M. bovis, M. kansasi, M. avium, M. fortuitum and on eighteen different strains of M. tuberculosis, isolated from human bronchial aspirates. The results obtained confirmed that the newly synthesized chemicals possessed a very interesting antitubercular activity, their MICs ranging from 4 micrograms/ml to 16 micrograms/ml.

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.

Abstract
The synthesis of new benzylidenaminoguanidine compounds is described. Some of these compounds were tested for antihypertensive activity in conscious unrestrained spontaneously hypertensive rats. The compounds examined possess a significant antihypertensive activity, qualitatively different from that of clonidine. For the tested compounds, the absence of the transient rise in blood pressure, which appears immediately after administration of clonidine-like drugs, is noteworthy.
