    • The invention provides compositions and methods for the direct dyeing of keratinous fibers, with particular regard to human hair on the head. The compositions of the invention contain novel anthraquinone mixtures in which each of the component anthraquinones has similar polarities. Compared with the known, commercially-available anthraquinone hair dye colorant, Disperse Blue 3 (DB 3), which comprises a mixture of anthraquinones having dissimilar polarities, the anthraquinone mixtures of the present invention surprisingly and advantageously were found to color hair more intensely and also to synergize to a greater extent with other anthraquinones, such as Disperse Violet 1 (DV 1), when used in hair dye formulations. The novel compound 1-[(2-hydroxyethyl)amino]-4-[(2-hydroxypropyl)amino]-9,10-anthracenedione is also disclosed.
    • 本发明提供了用于直接染色角质纤维的组合物和方法,特别是关于头部上的人发。 本发明的组合物含有新颖的蒽醌混合物,其中每种组分蒽醌具有相似的极性。 与已知的商业上可获得的蒽醌染发剂着色剂(包含具有不同极性的蒽醌的混合物)的分散蓝3(DB 3)相比,令人惊奇地和有利地发现本发明的蒽醌混合物更加强烈地染色头发, 当用于染发剂制剂时,与其它蒽醌(例如分散紫1(DV 1))更大程度地协同作用。 还公开了新化合物1 - [(2-羟乙基)氨基] -4 - [(2-羟丙基)氨基] -9,10-蒽二酮。

    • The present invention provides di-substituted acetalanthraquinone- based compounds of the Formulae (l)-(IV) that are useful for cellular staining and for light-based detection of biological material, e.g. fluorescence-based detection of biological material. These compounds may be used in hydrolysed or non-hydrolysed form. Also provided is a fluorescent complex that comprises a nucleic acid and an acetalanthraquinone-based compound of the invention; and a method of staining a biological sample comprising cells or other biological material containing nucleic acid, which method comprises contacting the biological sample with an acetalanthraquinone-based compound of the invention. In the Formulae (l)-(IV), A and B are each independently of formula -R a CH 2 CH(OR b ) 2 ; or one of A and B is of formula -R a CH 2 CH(OR b ) 2 and the other one is of formula: -NR b 2 .
    • 本发明提供了用于细胞染色和生物材料的基于光的检测的式(I) - (IV)的基于二取代乙蒽蒽醌的化合物。 基于荧光的生物材料检测。 这些化合物可以以水解或非水解形式使用。 还提供了包含核酸和本发明的基于蒽醌醌的化合物的荧光复合物; 以及对包含细胞或其他含有核酸的生物材料的生物样品进行染色的方法,该方法包括使生物样品与本发明的基于乙二氮蒽醌的化合物接触。 在式(1) - (IV)中,A和B各自独立地为式-R-CH 2 CH(OR b) <子> 2 ; 或者A和B中的一个具有式-R甲基CH 2 CH(OR b)2 2 另一种是具有下式的化合物:-NR 2
