acid derivatives attached to a tricyclic skeleton were prepared and evaluated as 5alpha-reductase inhibitors. Structure activity relationships for these compounds in terms of rat epididymis (type 2) 5alpha-reductase inhibitory activities reveal that 1) the substitution pattern at the 11-position of dibenz[b,e]oxepin influenced potency, 2) higher lipophilicity of the tricyclic skeleton improved potency
制备了一系列与三环骨架相连的4-苯氧基丁酸衍生物,并将其作为5α-还原酶抑制剂进行了评估。这些化合物在大鼠附睾(2型)5α-还原酶抑制活性方面的结构活性关系显示:1)苯并[b,e]氧杂环丁酮11位的取代模式影响药效; 2)三环的亲脂性更高骨架提高了效能,而该骨架中碱性氮原子的存在不利于效能,并且3)容忍了氮杂骨架8位正丁基的异丁基取代。在研究的三环化合物中,4- [3- [5-苄基-8-(2-甲基)丙基-10,11-二氢二苯并[b,f]氮杂-2-2-羧酰胺基]苯氧基]丁酸(26)是大鼠2型5α-还原酶的最有效抑制剂,浓度为0.1 microM。
