Synthesis and antitumor activity of alkyltriazenopyrazoles.

The chemical synthesis of certain mono- and bis-dialkyltriazenopyrazoles is described. In antitumor studies it was found that none of the compounds produced increase in life span (ILS) of L 1210 bearing mice or inhibition of adenocarcinoma 755 growth above the criteria established. The introduction of a second triazenogroup increases the toxicity of the compounds tested.
