A new efficient total synthesis of the phenazine 5,10-dioxide natural products iodinin and myxin and new compounds derived from them was achieved in few steps, a key-step being 1,6-dihydroxyphenazine di-N-oxidation. Analogues prepared from iodinin, including myxin and 2-ethoxy-2-oxoethoxy derivatives, had fully retained cytotoxic effect against human cancer cells (MOLM-13 leukemia) at atmospheric and
吩嗪5,10-二氧化物天然产物碘和粘菌素以及由它们衍生的新化合物的新有效全合成方法只需几个步骤即可完成,其中关键步骤是1,6-二羟基吩嗪二-N-氧化。由碘丁宁制备的类似物,包括粘菌素和2-乙氧基-2-氧代乙氧基衍生物,在大气和低氧水平下完全保留了对人类癌细胞(MOLM-13白血病)的细胞毒作用。此外,碘首次首次显示出对缺氧的选择性。白血病细胞死亡诱导的构效关系表明,N-氧化物功能水平对细胞毒性至关重要。还揭示了活性仅需要两种酚官能团中的一种,从而使另一种酚官能团被修饰而没有效力的损失。
