Cyanine and Indocyanine dye compounds and bioconjugates are disclosed. The present invention includes several cyanine and indocyanine dyes, including bioconjugates of the same, with a variety of bis- and tetrakis (carboxylic acid) homologues. The compounds of the invention may be conjugated to bioactive peptides, carbohydrates, hormones, drugs, or other bioactive agents. The small size of compounds of the invention allows favorable delivery to tumor cells as compared to larger molecular weight imaging agents. Further, use of a biocompatible organic solvent such as dimethylsulfoxide may be said to assist in maintaining the fluorescence of compounds of the invention. The compounds and bioconjugates herein disclosed are useful in a variety of medical applications including, but not limited to, diagnostic imaging and therapy, endoscopic applications for the detection of tumors and other abnormalities, localized therapy, photoacoustic tumor imaging, detection and therapy, and sonofluorescence tumor imaging, detection and therapy.
本发明涉及靛青和吲哚青染料化合物及其生物共轭物。本发明包括多种靛青和吲哚青染料,包括其生物共轭物,具有多种双和四羧酸同系物。本发明的化合物可与生物活性肽、碳水化合物、激素、药物或其他生物活性剂相结合。与分子量较大的成像剂相比,本发明的化合物大小较小,有利于向肿瘤细胞传递。此外,使用生物相容性有机溶剂如二甲基亚砜可以帮助维持本发明的化合物的荧光。本发明所披露的化合物和生物共轭物在多种医疗应用中有用,包括但不限于诊断成像和治疗、用于检测肿瘤和其他异常的内窥镜应用、局部治疗、光声肿瘤成像、检测和治疗,以及声致荧光肿瘤成像、检测和治疗。
