    convenient procedure for the preparation of the fluorescent dye 4′,5′-dichloro-2′,7′-dimethoxy-5(6)-carboxyfluorescein (JOE) is reported; the overall yield achieved starting from isovanillin is 10 times higher (40% vs 4%) compared to the known procedure. Isomers (5- and 6-) are easily chromatographically separable as pentafluorophenyl esters of 3′,6′-O-bis(cyclohexylcarbonyl) derivatives. Four non-nucleoside
    报道了一种方便的制备荧光染料4',5'-dichloro-2',7'-dimethoxy-5(6)-羧基荧光素(JOE)的方法。与已知方法相比,从异香草醛开始获得的总收率要高10倍(40%比4%)。异构体(5-和6--)易于色谱分离为3',6'- O-双(环己基羰基)衍生物五氟苯基酯。四种基于5和6异构体以及柔性6-己醇(AH)或刚性4- trans的非核苷JOE亚酰胺已经制备了-环己醇(ACH)接头,并将其用于寡核苷酸标记。已经研究了5'-JOE修饰的寡核苷酸的光谱和光物理性质。染料的荧光量子产率与接头的性质(刚性或柔性)以及与JOE残基非常接​​近的dG核苷的存在有关。
  • RADIOSENSITIVITY OF FLUOROPHORES AND USE OF RADIOPROTECTIVE AGENTS FOR DUAL-MODALITY IMAGING
    申请人:Immunomedics, Inc.
    公开号:US20160199524A1
    公开(公告)日:2016-07-14
    The present application discloses compositions and methods of use of dual-labeled molecules comprising a fluorescent probe and a radionuclide. The labeled molecules are of use for detection, imaging and/or diagnosis of diseased tissues, such as tumors. In preferred embodiments, the dual-labeled molecules are of use in pre-operative and/or intraoperative imaging, for example to detect margins of malignant tissues to facilitate surgical resectioning. In more preferred embodiments, a radioprotective agent such as an oxygen radical scavenger is used to decrease radiolysis of the fluorescent signal. The labeled molecules bind to a disease-associated antigen, such as a tumor-associated antigen. Exemplary molecules include antibodies, antibody fragments, bispecific antibodies, targetable constructs and targeting peptides, such as bombesin analogues.
    本申请公开了一种包含荧光探针和放射性核素的双标记分子的组合物及其使用方法。这些标记分子可用于检测、成像和/或诊断疾病组织,如肿瘤。在优选实施例中,双标记分子可用于术前和/或术中成像,例如检测恶性组织的边缘以便于手术切除。在更优选的实施例中,使用放射保护剂,如氧自由基清除剂,以减少荧光信号的辐解。标记分子结合到与疾病相关的抗原,如肿瘤相关抗原。示例分子包括抗体抗体片段、双特异性抗体、可靶向构建物和靶向肽,如炸弹素类似物。
