Photooxidation of primaquine (1) and 5-hydroxyprimaquine (5) afforded a blue dye for which o-quinone structure 4 was elaborated. Similar oxidation of N-ethoxyacetylprimaquine (10) afforded o-quinone 11. Tissue schizontocidal activity of 4 and 11, and bisquinolylmethine 3 prepared earlier, showed that none of them had noteworthy antimalarial activity, but all three produced methemoglobin.
伯氨喹(1)和5-羟基伯氨喹(5)的光氧化反应生成了一种蓝色染料,据此阐述了邻醌结构4。N-乙氧基乙酰伯氨喹(10)的类似氧化反应生成了邻醌11。4、11以及之前制备的双喹啉甲碱3的组织裂殖体杀灭活性表明,它们均无显著的抗疟活性,但这三种化合物都会产生高铁血红蛋白。
