3-biphenylylacetic acids (5a-n) and several alpha-methyl derivatives (5o-v) were prepared as analogues of a newly developed nonsteroidal antiinflammatory agent, 5'-chloro-5-methoxy-3-biphenylylacetic acid [1 (DKA-9), R = 4-C1Ph; R' = Me], and evaluated for antiinflammatory and analgesic activities using both carrageenan rat paw edema and AcOH writhing assays. Among them, 5-fluoro-3-biphenylylacetic acid (5m) showed
制备了一系列5',5-二取代的3-联苯基乙酸(5a-n)和几种α-甲基衍生物(5o-v)作为新开发的非甾体类抗炎药5'-氯-5-甲氧基-的类似物3-联苯基乙酸[1(DKA-9),R = 4-ClPh; R'= Me],并使用角叉菜胶大鼠爪水肿和AcOH扭体试验评估抗炎和止痛活性。其中,5-氟-3-联苯基乙酸(5m)具有最高的抗炎活性,而2-(3-联苯基苯基)丙酸(5o)具有最高的止痛活性。但是,在这些测定中,它们的效力不及1(R = 4-C1Ph; R'= Me)。
