Antitumor activity of 4-nitropyridazine 1-oxides and related compounds was tested with AH-13 system. Among these nitro compounds, 3, 6-dimethoxy-4-nitropyridazine 1-oxide (III) and 4-nitrocinnoline 1-oxide (XIII) were the most effective. 4-Nitropyridazine 1-oxide (I), 3, 6-dimethyl-4-nitropyridazine 1-oxide (II) and 3-alkoxy-4-nitro-6-chloropyridazine 1-oxides (VI, VII) were effective to some extent.
