A number of polychlorinated (phenoxyphenyl)acetic acids were prepared as close structural analogues of the antiinflammatory compound fenclofenac, [2-(2,4-dichlorophenoxy)phenyl]acetic acid. Increased potency was shown in several of these compounds, in particular, [2-(2,3,5,6-tetrachlorophenoxy) phenyl]acetic acid (8), which was 40 times more potent than fenclofenac in the adjuvant-induced arthritis
制备了许多多氯代(苯氧苯基)乙酸作为抗炎化合物芬氯芬酸[2-(2,4-二氯苯氧)苯基]乙酸的紧密结构类似物。这些化合物中的几种化合物,特别是[2-(2,3,5,6-四氯苯氧基)苯基]乙酸(8),显示出更高的效价,在佐剂诱导的关节炎筛查中,其效价比芬氯芬酸高40倍。 。在进一步的测试中,发现与消炎痛是等效的,但急性毒性(LD50和致溃疡性)的发生率大大降低。然而,在长期给药时,出现严重的毒性问题(包括贫血,中性粒细胞增多和严重的腹膜炎),这导致对该化合物的进一步研究工作被放弃。制备了另外三个类似物,它们含有桥接苯环的NH,S和SO部分。尽管NH化合物与上述O-连接的化合物和强效抗炎药双氯芬酸[2-[((2,6-二氯苯基)亚氨基]苯基]乙酸都具有非常相似的结构相似性,但在初筛中显示出较低的活性。同样,S桥或SO桥的类似物均未达到8的效价。
