摘要

We report the synthesis and biological in vitro activities of 16 new 2-quinoxalinecarbonitrile 1,4-di-N-oxides. These compounds present new basic lateral chains (piperazines and anilines) in the 3 position as well as different substituents in the 6 and/or 7 positions of the quinoxaline ring. Among piperazine derivatives, 4b (a 7-chloro-3-(4-methylpiperazin-1-yl) derivative) was the most potent (P = 0.5 x10(-6) M). In general, aniline derivatives were more potent and selective than the former, compound 12b (with a 4-(methylphenyl)amino moiety in the 3 position and a chlorine atom in the 7 position) being the best one (P = 3 x 10(-6) 16).
