  Antipsoriatic Anthrones with Modulated Redox Properties. 2. Novel Derivatives of Chrysarobin and Isochrysarobin-Antiproliferative Activity and 5-Lipoxygenase Inhibition

  摘要：

  A novel series of 2- and 3-substituted 1,8-dihydroxy-9(10H)-anthracenones were synthesized and tested for their inhibitory activity against 5-lipoxygenase (5-LO) in bovine polymorphonuclear leukocytes and the growth of human keratinocytes. Structure-activity relationships are discussed with respect to the following redox properties of the compounds: reactivity against 2,2-diphenyl-1-picrylhydrazyl, generation of hydroxyl radicals as measured by deoxyribose degradation, and inhibition of lipid peroxidation in model membranes. Inhibition of cell proliferation seemed to be related to these properties, whereas 5-LO inhibition was not. Within a class of structural analogs the activity against 5-LO, which was markedly improved as compared to that of the antipsoriatic drug anthralin, correlated well with the overall lipophilicity. Even though a number of compounds in this series enhanced oxidative damage to nonlipid molecules such as deoxyribose, their antioxidant properties predominate in membrane lipids. Among the prooxidant compounds were also the most potent antiproliferative agents (IC50 values in the 10(-7) M range).

  Novel anthraquinone inhibitors of human leukocyte elastase and cathepsin G

  摘要：

  A large series of variously substituted anthraquinones has been synthesized and assayed for inhibitory capacity against human leukocyte elastase (HLE) and cathepsin G (CatG), two serine proteinases implicated in diseases characterized by the abnormal degradation of connective tissue, such as pulmonary emphysema and rheumatoid arthritis. It was found that 2-alkyl-1,8-dihydroxyanthraquinone analogues are competitive inhibitors of HLE with IC50 values ranging from 4 to 10-mu-M, and also inhibit CatG with IC50 values ranging from 25 to 55-mu-M. Consequently, analogues containing the 2-alkyl-1-hydroxy-8-methoxyanthraquinone substitution pattern inhibit HLE to the same magnitude as for the compounds above, but show very little inhibition of CatG. Anthraquinones containing long, hydrophobic n-butyl carbonate moieties in the 1- and 8-positions in conjunction with a third hydrophobic substituent in the 2- or 3-position are highly selective for HLE, with K(i) values in the range of 10(-7) M. All of the inhibitors described are completely reversible, with no evidence of acyl-enzyme formation detected.

• Syntheses of Anthracenones. 1. Sodium Dithionite Reduction of <i>peri</i>-Substituted Anthracenediones

  日期：1996.1.1

  The reaction of peri-substituted anthracenediones with sodium dithionite in dimethylformamide and water has been investigated. The system selectively reduces the carbonyl group flanked by the peri substituents of the anthracenediones to give the corresponding 4,5-disubstituted 9(10H)-anthracenones and thus provides a route to anthracenones which are otherwise difficult to obtain.

  研究了过取代的蒽二酮与连二亚硫酸钠在二甲基甲酰胺和水中的反应。该体系选择性地还原蒽二酮的周围取代基侧接的羰基，得到相应的4，5-二取代的9（10H）-蒽酮，因此提供了一种难以获得的蒽酮途径。可以容许许多官能团，该反应与起始的蒽二酮的周边烷氧基和不饱和侧链的存在相容，并且还原不超过蒽酮阶段。然而，蒽酮的形成取决于周围取代基的性质。从1，8-二甲基取代的蒽二酮和没有取代基的母体化合物没有得到产物。
