Synthesis, physicochemical properties, and antitumor activities of analogs of 1-phenyl-3-benzyl-3-methyltriazenes.

To study the effect of substituents on the antitumor activities of analogs of 1-phenyl-3-benzyl-3-methyltriazenes, a series of compounds was designed and synthesized in which the substituent on the 1-phenyl was an electron-withdrawing group and the substituent on the 3-benzyl had a broad range of physicochemical properties. Of the 13 analogs prepared and tested against Sarcoma-180 in the mouse, five showed significant activity. The results were submitted to discriminant analysis to determine structure-activity relationships.
