Two methods of N-substitution were applied to 5-arylidene-6-methyl-3-(4H)-pyridazinones. The resulting derivatives were tested in order to determine the area of pharmacological activity. Most compounds exhibited a dose-dependent analgesic activity. Introduction of a benzoyl substituent in the 2-position of the pyridazinone ring 2j induced the most potent activity.
