A series of 2-phenyl-4,5,6,7-tetrahydro[b]benzothiophene derivatives were synthesized and evaluated for in vitro COX inhibitory potential. Within the series, compounds 4a, 4j, 4k, and 4q were identified as potential and selective COX-2 inhibitors with COX-2 IC50 in 0.31-1.40µM range; COX-2 selectivity index (SI)=48.8-183.8 range and they showed percent PGE-2 inhibitory activity in the range of 25.4-46
合成了一系列的2-苯基-4,5,6,7-四氢[b]苯并噻吩衍生物,并对其体外COX抑制潜力进行了评估。在该系列中,化合物4a,4j,4k和4q被鉴定为潜在的和选择性的COX-2抑制剂,COX-2 IC50在0.31-1.40µM的范围内。COX-2选择性指数(SI)= 48.8-183.8范围,它们显示的PGE-2抑制活性百分比在25.4-46.9范围内。此外,化合物4a,4j,4k和4q表现出有效的抗炎活性,在180分钟时爪体积百分比增加范围为21.1-30.5,而在角叉菜胶诱导的大鼠爪水肿测定中,塞来昔布在180相同剂量下显示19.6%的百分比升高。通过MTT测定法测定的细胞活力在浓度达到80μM时均未显示出细胞毒性。
