4-dimethylpyrano[2,3-c]pyrazol-6-one derivatives and 1-substituted 1,6-dihydro-4-methyl-6-oxopyrano[2,3-c]pyrazole-3-acetic acids were synthesized and examined for their analgesic and antiinflammatoryactivities. Most of these compounds showed more prominent analgesic activities than antiinflammatoryactivities, and this result was similar to that of aminopyrine. Among these compounds, 1,3,4-trimethylpyrano[2
