Antituberculotic 4'-Cyclohexylthiobenzanilides: Combination of Free-Wilson Method in QSAR with Topliss Approach

Abstract

On the basis of a preliminary study of antimycobacterial activity of thiobenzanilides against Mycobacterium kansasii, a group of 4'-cyclohexylthiobenzanilids have been prepared which exhibit a significant activity against the microorganism mentioned. The whole set of 35 thiobenzanilides was tested with Mycobacterium tuberculosis, and on the basis of QSAR analysis conclusions have been made with regard to prognostics of structures suitable for further studies. The problem was solved by the method by Free and Wilson combined with the Topliss approach and by a Hansch type analysis.
