Abstract: The invention relates to novel anthracene compounds useful in the treatment of allergic, inflammatory conditions, tumor conditions and therapeutic compositions containing such compounds. The compounds of the present invention are 9-acyloxy-substituted 1,5-dichloroanthracene or analogs thereof. According to the practice of the invention, there are provided 9-acyloxy substituted 1,5-dichloroanthracene compounds according to formula III: wherein R represents a straight or branched chain alkyl group having 1 to 6 carbons which may be substituted with one or more groups of R1, or R represents phenyl or benzyl which may be substituted with one or two groups of R2; wherein R1 is selected from the group consisting of halogen, —NO2, —OCH3, OCH2CH3, and —OCH2CH2CH3; and wherein R2 is selected from the group consisting of a straight or branched chain alkyl group having 1 to 4 carbons, halogen, —NO2, —OCH3, —OCH2CH3, and —OCH2CH2CH3.
