COX-2: IC50 = 0.17 μM, SI >588). Molecular docking studies using the catalytic site of COX-1 and COX-2, respectively, provided complementary theoretical support for the obtained experimental biological structure–activity relationship data. Results of molecular docking studies revealed that COX-2 pharmacophore SO2NH2 in compound 30 is positioned in the secondary pocket of COX-2 active site; with the
通过引入连接到一个芳基环和各种取代基(H,F,Cl,CH 3或CH 3的环氧化酶-2(COX-2)药效团SO 2 NH 2),设计和合成一组新的1,4-二芳基取代的三唑。OCH 3)连接到另一个芳基环上。通过增加烷基接头链的大小[(–CH 2)n,其中n = 0、1、2],研究了化合物大小和柔韧性对COX-1 / COX-2抑制效能和选择性的影响。体外COX-1 / COX-2抑制的研究表明,所有的化合物(14 - 18,21 - 25和28 - 与COX-1同工酶(IC 50 = 21.0至> 100μM范围)相比,32)是更有效的COX-2同工酶抑制剂(IC 50 = 0.17–28.0μM范围)。在1,4二芳基取代的三唑类中,4- 2- [4-(4-氯-苯基)-[1,2,3]三唑-1-基]-乙基}-苯磺酰胺(化合物30)表现出最高的COX-2抑制效能和选择性(COX-1:IC 50
