Page 23-24, (2008/06/13)
The invention provides novel anthraquinone compositions that are useful as broad-spectrum quenchers of fluorescence and provides methods for making and using them. The anthraquinone quenchers can be conjugated to a variety of biologically relevant compounds, including lipids, nucleic acids, polypeptides, and more specifically antigens, steroids, vitamins, drugs, haptens, metabolites, toxins, environmental pollutants, amino acids, peptides, proteins, nucleotides, oligonucleotides, polynucleotides, carbohydrates, and their analogs. The invention also provides kits comprising, in one or more containers, at least one anthraquinone quencher dye composition of the present invention, and instructions for using that composition.

Aminoanthraquinones are generally useful as dyes and coloring agents. But known methods of synthesizing unsymmetrically substituted 1,4-diaminoanthraquinones are tedious and complex. A simple and efficient method is provided for preparing 1,4-diaminoanthr

Various aminoathraquinones can be easily prepared from (tosyloxy)anthraquinone precursors.Unsymmetrical 1,4-diaminoanthraquinones are prepared via the intermediate monoamino mono(tosyloxy)anthraquinones derived from 1,4-bis(tosyloxy)anthraquinone.The ability to remove tosylate groups sequentially is controlled by the proper selection of solvent and temperature.Hindered 1,4-diamino and 1-aminoanthraquinones are prepared from their corresponding tosyl derivatives, and the amount of steric hindrance present can be succesfully correlated with spectral and color data.The methods described offer advantages over the literature preparations of these compounds.
