Özet

Some N-(3,5-di-/1,3,5-trimethylpyrazole-4-yl)-4-substitutedbenzamide derivatives were prepared as possible antiociceptive-antimicrobial agents. New amide derivatives (3-12) were synthesized by reacting 4-amino-3,5-di and 1,3,5-trimethylpyrazoles with 4-substitutedbenzoyl chlorides. Hotplate and tail-immersion tests were used for the determination of the antinociceptive activity. Morphine, was used as a standard test drug. All compounds were administered at a dose of 100 mg/kg ip and some of them had significant antinociceptive activity in both tests. Compound 10 (N-(1,3,5-trimethylpyrazole-4-yl)-4-bromobenzamide), was the most active one in both tests among the compounds. The antinociceptive activity of the compounds 10, 11 (N-(1,3,5-trimethylpyrazole-4-yl)-4-chlorobenzamide), and 12 (N-(1,3,5-trimethylpyrazole-4-yl)-4-fluorobenzamide), started at 30 minutes and continued up to 150 minutes in the hotplate test. Also compounds were tested for their in vitro antimicrobial activity, but exhibited weak antibacterial activity.
