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.
本发明涉及一种新型蒽醌化合物,可用于治疗过敏、炎症、肿瘤等疾病,以及含有该化合物的治疗组合物。本发明的化合物是9-酰氧基取代的1,5-二氯蒽醌或其类似物。根据本发明的实践,提供了式III所示的9-酰氧基取代的1,5-二氯蒽醌化合物:其中R表示直链或支链烷基,其具有1至6个碳原子,可以用一个或多个R1基团取代,或者R表示苯基或苄基,可以用一个或两个R2基团取代;其中R1选自卤素、—NO2、—OCH3、OCH2CH3和—OCH2CH2CH3组成的群;其中R2选自直链或支链烷基,其具有1至4个碳原子,卤素、—NO2、—OCH3、—OCH2CH3和—OCH2CH2CH3组成的群。
