A novel series of indole-3-alkanoic acids with varied N-benzyl substituents were synthesized as nonsteroidal inhibitors of steroid 5 alpha-reductase. The structure-activity relationships in this series were studied and the optimum carboxylic acid side chain was butyric acid. Furthermore, compounds with a diaryl substituent at the 1-position of the indole ring displayed strong inhibitory activities
合成了一系列具有变化的N-苄基取代基的新型吲哚-3-链烷酸作为甾体5α-还原酶的非甾体抑制剂。研究了该系列中的构效关系,最佳羧酸侧链为丁酸。此外,在吲哚环的1-位具有二芳基取代基的化合物在体外显示出强的抑制活性。在这些衍生物中,4- [1-(6,6-二甲基-6H-二苯并[b,d]吡喃-3-基)甲基吲哚-3-基]丁二酸(FR119680)在体外具有很高的抑制活性。在rat割的年轻大鼠模型中具有抗大鼠前列腺5α-还原酶(IC50 = 5.0 nM)的良好体内活性。
