A series of novel 5-substituted-2, 3-diarylthiophenes has been synthesized and found to be active in the rat adjuvant arthritis (AA) model and/or in the yeast-induced hyperalgesia (Randall-Selitto) assay. Among the compounds synthesized herein, 2-(4-fluorophenyl)-3-[4-(methylsulfonyl)phenyl]-5-(trifluoromethyl)thiophene (6a) exhibited the most potent activities on AA, collagen-induced arthritis (CIA) and the delayed-type hypersensitivity response to type II collagen. 5-Bromo-2-[4-(methylamino)phenyl]-3-[4-(methylsulfinyl)phenyl]thiophene (38) is also a potent inhibitor of AA, CIA, hyperalgesia and in vitro tumor necrosis factor-α production.
一系列新型的5-取代-2,3-二芳基噻吩被合成,并发现它们在大鼠佐剂性关节炎(AA)模型和/或酵母诱导的高痛敏(Randall-Selitto)测定中具有活性。在这里合成的化合物中,2-(4-氟苯基)-3-[4-(甲基磺酰基)苯基]-5-(三氟甲基)噻吩(6a)对AA、胶原诱导的关节炎(CIA)以及对II型胶原的迟发型超敏反应表现出最强的活性。5-溴-2-[4-(甲基氨基)苯基]-3-[4-(甲基亚磺酰基)苯基]噻吩(38)同样是AA、CIA、高痛敏和体外肿瘤坏死因子-α产生的有效抑制剂。
