Abstract

Design, results of in vitro antimycobacterial evaluation, and study of structure-activity relationships of various pyrazinecarboxylic acid reversible derivatives are presented. This review deals with some pyrazinamide analogues/prodrugs derived from Nphenylpyrazine- 2-carboxamides (1), arylaminopyrazine-2,5-dicarbonitriles (2), aryl/alkylsulphanylpyrazines (3,4), and aroylpyrazines (5) effecting > 50% inhibition in the primary antimycobacterial screen. The promising pyrazine candidates for further antimycobacterial evaluation were discovered. Results give good view onto structure-activity relationships of these analogues and promise even better activity of new compounds prepared after some structure optimization experiments.
