Antitubercular active compounds based on oxyphosphorus acids derivatives of substituted salicylanilides of general formula I, wherein each R1, R2 is independently H, halogen, or NO2; each R3, R4 is independently H, halogen, NO2, or CF3; R5 is H, halogen, or NO2; R6 is C2- C16alkyl, C6-C18aryl, C6-C18aryloxy, or C6-C18arylC2-C16alkyloxy; R7 is C6-C18aryl, C6- C18aryloxy, C6-C18aryl C2-C16alkyloxy, or R7 is missing; R8 is H or single bond to phosphorus atom. These compounds can be obtained by simple synthetic procedures and they show high in vitro antimycobacterial activity including multidrug-resistant strains. The invention provides also the use of these compounds as antitubercular and/or antimycobacterial drugs as well as a pharmaceutical preparation containing as an active substance compound of general formula I.
