(COX-1/2) and 5/15-lipoxygenases (5/15-LOX) that exhibit vivo antiinflammatory and analgesic activities. Among this class of compounds, 3-(4-methanesulfonylphenyl)-1-(4-fluorophenyl)prop-2-yn-1-one (13h) was identified as a potent and selective inhibitor of COX-2 (COX-2 IC50 = 0.1 microM; SI = 300), being 5-fold more potent than rofecoxib (COX-2 IC50 = 0.5 microM; SI > 200). In a rat carrageenan-induced
设计,合成和评估了一组具有C-3 p-SO2Me COX-2药效基团的1,3-二芳基丙-2-yn-1-ones(13、17、23、26和27),作为潜在的双重抑制剂环氧合酶1/2(COX-1 / 2)和5 / 15-脂氧合酶(5 / 15-LOX)具有体内抗炎和镇痛作用。在这类化合物中,3-(4-甲磺酰基苯基)-1-(4-氟苯基)丙-2-炔-1-酮(13h)被确定为有效和选择性的COX-2抑制剂(COX-2 IC50 = 0.1 microM; SI = 300),效力比罗非昔布高5倍(COX-2 IC50 = 0.5 microM; SI> 200)。在大鼠角叉菜胶诱导的爪水肿测定中,口服30 mg / kg剂量后3 h,13h表现出中等的抗炎活性(炎症抑制26%)。相关的双重COX-1 / 2和5 / 15-LOX抑制剂3-(4-甲磺酰基苯基)-1-(4-氰基苯基)丙-2-炔-1-酮(13g,COX-1
