of isoquinolin-5,8-dione. This hydroxyl group-guided substitution was also applied to selected heterocycles and addressed the regioselectivity issue of quinones. This study has provided an expeditious pathway from isoquinolin-5-ol (5) to ellipticine (1) and isoellipticine (2), which benefits the comprehensive comparison of their activity. Compounds 1 and 2 displayed marked MYLK4 inhibitory activity

氨基醌的生成有助于
异喹啉-5,8-二酮的区域选择性取代。这种羟基引导的取代也适用于选定的杂环,并解决了醌的区域选择性问题。本研究提供了从isoquinolin-5-ol (5)到
玫瑰树碱(1)和异
玫瑰树碱(2)的快速途径,有利于综合比较它们的活性。化合物1和2表现出显着的MYLK4抑制活性,IC50值分别为7.1和6.1 nM。在
