In a search for novel nonsteroidal inhibitors of human prostatic 5 alpha-reductase, we found a new series of phenoxybenzoic acid derivatives to be potent human prostatic 5 alpha-reductase inhibitors. Among them, 4-(biphenyl-4-yloxy)benzoic acid derivatives (2n, YM-31758), 2o and 2s showed more potent inhibitory activities than finasteride with IC50 values of 0.87, 0.67 and 0.56 nM, respectively. The
在寻找人类前列腺5α-还原酶的新型非甾体抑制剂时,我们发现了一系列新的苯氧基苯甲酸衍生物是有效的人类前列腺5α-还原酶抑制剂。其中,4-(联苯-4-基氧基)苯甲酸衍生物(2n,YM-31758),2o和2s显示出比非那雄胺更有效的抑制活性,IC50值分别为0.87、0.67和0.56 nM。通过分子建模分析计算出苯氧基苯甲酸衍生物2d-2i的优化结构,发现羧基碳原子与苯基质心(苯环C)之间的合适距离为9-11一个范围。
