Abstract
According to our previous study 29 derivatives of 2-hydroxy-3-(4-phenylpiperazin-1-yl)-propylphenylcarbamates were tested for in vitro antimycobacterial activity against potential pathogenic strains Mycobacterium kansasii and Mycobacterium avium. The variations in group of compounds were by the substitution on phenyl rings. The Free-Wilson method was used to evaluate structure-antimycobacterial activity relationships. The advantage of compounds under study is in the activity against M. kansasii.
