Received: 8 September 2009; in revised form: 1 October 2009 / Accepted: 13 October 2009 / Published: 20 October 2009 Abstract: The condensation of chlorides of substituted pyrazinecarboxylic acids with ring- substituted anilines yielded twelve substituted pyrazinecarboxylic acid amides. The synthetic approach, analytical, and lipophilicity data of the newly synthesized compounds are presented. Two antituberculosis assays were used. Firstly, the antimycobacterial activity against four different Mycobacterium strains in a series of pyrazine derivatives was investigated. Secondly, the antimycobacterial evaluation was performed at the Tuberculosis Antimicrobial Acquisition and Coordinating Facility (TAACF) program.
