Abstract: Condensation of chlorides of substituted pyrazine-2-carboxylic acids with ring-substituted anilines yielded a series of anilides of 6-chloropyrazine-2-carboxylic, 5-(1,1-dimethylethyl) pyrazine-2-carboxylic or 6-chloro-5- (1,1-dimethylethyl)pyrazine-2-carboxylic acids. Products were tested for their antimycobacterial. antifungal, and photosynthesis-inhibiting activity. Some of them exhibited significative activity against Mycobacterium tuberculosis (inhibition > 50 % at MIC = 12.5 μg cm-3). The most active compound (88 %) was 6-chloro-5-(1,1-dimethylethyl)pyrazine-2- carboxylic acid 3-fluoroanilide.
