A series of 4,5-diaryl-2-(substituted thio)-1H-imidazoles was synthesized and evaluated as antiinflammatory and analgesic agents in the rat adjuvant induced arthritis assay and the mouse phenyl-p-benzoquinone writhing (PQW) assay. Several analogues were found to be more potent than phenylbutazone and indomethacin. Structure-activity relationships are discussed. One of the compounds, 4,5-bis(4-fluorophenyl)-2-[(1
合成了一系列的4,5-二芳基-2-(取代硫代)-1H-咪唑,并在大鼠佐剂诱导的关节炎试验和小鼠苯基-对苯醌扭曲(PQW)试验中用作抗炎和镇痛药。发现几种类似物比苯基丁a和消炎痛更有效。讨论了构效关系。发现其中一种化合物4,5-双(4-氟苯基)-2-[((1,1,2,2-四氟乙基)-磺酰基] -1H-咪唑(8d,tiflamizole)是在大鼠佐剂诱导的关节炎试验中具有消炎痛的作用,目前正在作为抗关节炎药进行临床试验。
