Abstract:
The invention relates to the dyeing of keratin materials using thiol and disulfide, indole-derived, styryl fluorescent dyes. The invention relates to a dye composition comprising thiol and disulfide, indole-derived, styryl fluorescent dyes and to a dyeing process with a lightening effect on keratin materials, in particular keratin fibers, especially human keratin fibers such as the hair, using said composition. It similarly relates to novel thiol and disulfide, indole-derived, styryl fluorescent dyes and to the uses thereof in lightening keratin materials. This composition makes it possible to obtain a lightening effect which is particularly resistant and visible on dark keratin fibers.
Abstract:
Cyanine dyes, as well as bioconjugates thereof, useful for diagnostic imaging and therapy are disclosed. The conjugates include several cyanine dyes with a variety of bis- and tetrakis (carboxylic acid) homologues. Dyes of the invention may be conjugated to bioactive peptides, carbohydrates, hormones, drugs, or other bioactive agents. The small size of the compounds allows more favorable delivery to tumor cells as compared to larger molecular weight imaging agents. The various dyes are useful over the range of 350 to 1,300 nm; the exact range being dependent upon the particular dye. The use of a biocompatible organic solvent such as dimethylsulfoxide helps to maintain the fluorescence of the compounds. The inventive compounds are useful for diagnostic imaging and therapy, in endoscopic applications for the detection of tumors and other abnormalities, for localized therapy, for photoacoustic tumor imaging, detection and therapy, and for sonofluorescence tumor imaging, detection and therapy.
