Following our previous research on anti-inflammatory drugs (NSAIDs), we report on the design and synthesis of 4-(aryloyl)phenyl methyl sulfones. These substances were characterized for their capacity to inhibit cyclooxygenase (COX-1 and COX-2) isoenzymes. Molecular modeling studies showed that the methylsulfone group of these compounds was inserted deep in the pocket of the human COX-2 binding site
在我们先前对消炎药(NSAIDs)的研究之后,我们报告了4-(芳酰基)苯基甲基砜的设计和合成。这些物质的特征在于它们具有抑制环氧合酶(COX-1和COX-2)同工酶的能力。分子模型研究表明,这些化合物的甲基砜基团以无法阻止氢与Arg120,Ser353和Tyr355通过氧原子键合的方向插入人COX-2结合位点的口袋深处。所述Ñ -arylindole 33是COX-2的最有效的抑制剂,也是最选择性(COX-1 / COX-2的IC 50之比为262)。吲哚衍生物33进一步在体内测试了其在大鼠中的抗炎活性。该化合物显示出比布洛芬更大的抑制活性。其它化合物(20,26,9,和30)显示出对角叉菜胶诱导的炎症活性强。后一种化合物在体外抑制人细胞株K562,NCI-H460和HT-29增殖的能力较弱。
