A series of (1H-1,2,3-triazol-4-yl)methoxybenzaldehyde derivatives containing an anthraquinone moiety were synthesized and identified as novel xanthine oxidase inhibitors. Among them, the most promising compounds 1h and 1k were obtained with IC50values of 0.6?μM and 0.8?μM, respectively, which were more than 10-fold potent compared with allopurinol. The Lineweaver-Burk plot revealed that compound 1h acted as a mixed-type xanthine oxidase inhibitor. SAR analysis showed that the benzaldehyde moiety played a more important role than the anthraquinone moiety for inhibition potency. The basis of significant inhibition of xanthine oxidase by 1h was rationalized by molecular modeling studies.

The invention belongs to the technical field of medicine, and particularly relates to 2-substituted-9,10-anthraquinone compounds represented by the general formula I, the general formula II, the general formula III and the general formula IV, and pharmaceutically acceptable salts, hydrates or solvates and pharmaceutically acceptable carriers thereof. A preparation method comprises the steps: with phthalic anhydride as a starting material, carrying out a Friedel-Crafts reaction, concentrated sulfuric acid dehydration, NBS bromization and sodium azide substitution, generating a key intermediate 2-azide methyl-9,10-anthraquinone, and finally in the presence of copper sulfate pentahydrate and vitamin C, carrying out a Husigen cycloaddition reaction with substituted alkyne; or carrying out concentrated sulfuric acid dehydration, cyclization, chromium trioxide oxidation and thionyl chloride chlorination, to obtain anthraquinone-2-formyl chloride, then carrying out an acylation reaction with various L-amino acid methyl esters, further hydrolyzing, and thus obtaining the target compounds. The prepared compounds show good results in in-vitro antitumor activity tests.
