Retinoic acid receptor alpha (RARα) antagonist ER-50891 and 15 analogs were prepared and tested in vitro for potency and selectivity at RARα, RARβ, and RARγ using transactivation assays. Minor modifications to the parent molecule such as the introduction of a C4 tolyl group in place of the C4 phenyl group on the quinoline moiety slightly increased the RARα selectivity but larger substituents significantly
制备视黄酸受体 α (RARα) 拮抗剂 ER-50891 和 15 种类似物,并使用反式激活测定在体外测试对 RARα、RARβ 和 RARγ 的效力和选择性。对母体分子进行细微修饰,例如引入 C4 甲苯基取代喹啉部分上的 C4 苯基,略微提高了 RARα 的选择性,但较大的取代基显着降低了效力。用三唑、酰胺或双键取代 ER-50891 的吡咯部分,产生非活性化合物。 ER-50891被发现在雄性小鼠肝微粒体中稳定,并在雄性小鼠中进行了测试,以评估其对精子发生的影响。观察到对精子发生的特征性影响,尽管是适度且短暂的。
