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 antiinflammatory activities. Most of these compounds showed more prominent analgesic activities than antiinflammatory activities, and this result was similar to that of aminopyrine. Among these compounds, 1,3,4-trimethylpyrano[2
一系列新的1-和2-取代的3,4-二甲基吡喃并[2,3-c]吡唑-6-一衍生物和1-取代的1,6-二氢-4-甲基-6-氧杂吡喃并[2,3-合成了c]吡唑-3-乙酸,并检查了它们的镇痛和抗炎活性。这些化合物大多数显示出比抗炎活性更突出的镇痛活性,并且该结果与氨基比林相似。在这些化合物中,显示1,3,4-三甲基吡喃并[2,3-c]吡唑-6(1H)-one和2,3,4-三甲基吡喃并[2,3-c]吡唑-6(2H)-one比氨基比林更有效的镇痛作用。
