title: Studies on pyrazine derivatives. Part VII. Synthesis and tuberculostatic activity of some pyrazine amidines and amidoximes.
abstract: In the reaction of 2-cyano-6-alkylaminopyrazines with sec. amines in the presence of anhyd. AlCl3 amidines 1-13 were obtained. From pyrazine-2-imidoesters, 2-cyano-pyrazines and pyrazine-2-carbothioamides and hydroxylamine, amidoximes 14-49 were easily prepared. These new compounds were, however, of little tuberculostatic activity (MIC between 31.5-2000 mug/cm3).
