title: Preparation and antitumor activity of 1-aryl-3,3-dimethyltriazene derivatives.
abstract: Several 1-aryl-3,3-dimethyltriazene derivatives have been synthesized and tested for their antitumor activity against the TLX5 lymphoma in mice. These compounds are characterized by the presence of a carbonyl group bound to the benzene nucleus in the para position to the triazene funciton. Three p-sulfamoyl derivatives have also been included and proved to be inactive. Among the carbonyl derivatives compounds 1 and 20, which can be used as reference, cause ILS of about 50%, respectively, at four and three dose levels. Compound 16, the o-nitro-phenylhydrazone of the hydrazide 1, is active at all six dose levels studied. The adduct 19, obtained from the same hydrazide and p-nitrobenzaldehyde, is active at four dose levels, and the ILS values at two optimum doses are significantly greater than those caused by compound 1.
