A process for the preparation of hydroxyl substituted anthraquinones is described. The process couples a phthalic anhydride (substituted or unsubstituted) to benzene ring moiety substituted with at least two hydroxyl groups. Remaining hydroxy groups were converted to methoxy groups in some anthraquinones. The compounds are particularly useful for the treatment of parasitic diseases. Also, a method of treating or preventing malaria, filariasis schistosomiasis and other parasitic diseases using anthraquinones.
描述了一种制备羟基取代蒽醌的方法。该方法将邻苯二甲酸酐(取代或未取代)与至少有两个羟基取代的苯环部分偶联。在一些蒽醌中,剩余的羟基被转化为甲氧基基团。这些化合物特别适用于治疗寄生虫病。此外,还提供了一种使用蒽醌治疗或预防疟疾、丝虫病和血吸虫病等寄生虫病的方法。
