developed as Lamellarin isosters. Synthesis was achieved from indoles after a four-step pathway sequence involving C-3 iodination, a Suzuki cross-coupling reaction, and a one pot deprotection/lactonisation step. Twenty final compounds were tested in order to determine their activity against topoisomerase I and kinases, the two major biological activities of Lamellarins. One newly synthesized derivative exhibited
开发了取代的chromeno [3,4- b ]吲哚文库作为lamellarin等位基因。在涉及C的四步路径序列之后,由吲哚完成合成-3碘化,Suzuki交叉偶联反应和一锅脱保护/内酯化步骤。测试了二十种最终化合物以确定它们对拓扑异构酶I和激酶(Lamellarins的两种主要生物学活性)的活性。一种新合成的衍生物显示出强大的拓扑异构酶活性,可与参比化合物(例如喜树碱和lamellarin)相比,但激酶抑制作用较弱。其他两种先导化合物被鉴定为新的纳摩尔DYRK1A抑制剂,其他几种药物影响亚微摩尔范围内的激酶。这些结果将使我们能够使用chromeno [3,4- b ]吲哚作为药效团来开发有效治疗涉及DYRK1A的神经系统或肿瘤性疾病的方法。
