NOVEL ANTHRAQUINONES AND PROCESS FOR THE PREPARATION AND METHOD OF USE THEREOF

摘要

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.
