ANTHRAQUINONE QUENCHER DYES, THEIR METHODS OF PREPARATION AND USE

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.

15N NMR STUDY OF AMINO-IMINO TAUTOMERISM IN DERIVATIVES OF 1,4-BIS(SUBSTITUTED AMINO)-9,10-ANTHRAQUINONES AND 1,4-BIS(SUBSTITUTED AMINO)-2,3-DIHYDRO-9,10-ANTHRAQUINONES

The 15N chemical shifts and 1J(15N,H) coupling constants of 1,4-bis(substituted amino)-9,10-anthraquinones and 1,4-bis(substituted amino)-2,3-dihydro-9,10-anthraquinones indicate that these derivatives exist as true aminoderivatives except for 1,4-bis(phenylamino)-2,3-dihydro-9,10-anthraquinone which forms a tautomeric mixture of the amino and imino forms in deuteriochloroform and hexadeuteriodimethyl sulphoxide.
