Cyanine dye bioconjugates useful for diagnostic imaging and therapy are disclosed. The conjugates include several cyanine dyes with a variety of bis- and tetrakis (carboxylic acid) homologs. The compounds 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 1300 nm, the exact range being dependent upon the particular dye. The use of 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 sonofluoresence tumor imaging, detection and therapy.
揭示了用于诊断成像和治疗的青菁染料生物共轭物。这些共轭物包括几种青菁染料,具有各种双和四(羧酸)同系物。这些化合物可以与生物活性肽、碳水化合物、激素、药物或其他生物活性剂结合。与分子量较大的成像试剂相比,这些化合物的小尺寸使其更有利于输送到肿瘤细胞。各种染料在350到1300纳米范围内是有用的,确切范围取决于特定的染料。二甲基亚砜的使用有助于保持化合物的荧光。这些创新的化合物在诊断成像和治疗中很有用,用于内窥镜应用以检测肿瘤和其他异常,用于局部治疗,用于光声肿瘤成像、检测和治疗,以及用于声荧光肿瘤成像、检测和治疗。
