The present invention relates to novel quinoline derivatives, such as substituted 1-(2-chloroquinolin-3-yl)-4-dimethylamino-2-(naphthalen-1-yl)-1- phenylbutan-2-ols, to a method for producing same, and also to the use thereof as antimycobacterial agents, in particular to 5,6,7-substituted 1-(2-chloroquinolin-3-yl)-4-dimethylamino-2-(naphthalen-1-yl)-1- phenylbutan-2-ols of general formula (I), where R1 is Н or methoxy, R2 is Н, methoxy or -O-(CH2)n-O-, R3 is Н, methoxy or -O-(CH2)n-O-, n=1-2, and also to the pharmaceutically acceptable salts thereof with acids which exhibit activity in relation to mycobacteria. The invention also relates to a method for producing compounds of formula (I), which consists in interacting corresponding arylquinolines with an aromatic ketone and using said compounds as an active principle in the creation of anti-tubercular medicinal preparations.
