    An Activity-Based Near-Infrared Glucuronide Trapping Probe for Imaging β-Glucuronidase Expression in Deep Tissues
    摘要:
    beta-glucuronidase is an attractive reporter and prodrug-converting enzyme. The development of near-IR (NIR) probes for imaging of beta-glucuronidase activity would be ideal to allow estimation of reporter expression and for personalized glucuronide prodrug cancer therapy in preclinical studies. However, NIR glucuronide probes are not yet available. In this work, we developed two fluorescent probes for detection of beta-glucuronidase activity, one for the NIR range (containing IR-820 dye) and the other for the visible range [containing fluorescein isothiocyanate (FITC)], by utilizing a difluoromethylphenol-glucuronide moiety (TrapG) to trap the fluorochromes in the vicinity of the active enzyme. beta-glucuronidase-mediated hydrolysis of the glucuronyl bond of TrapG generates a highly reactive alkylating group that facilitates the attachment of the fluorochrome to nucleophilic moieties located near beta-glucuronidase-expressing sites. FITC-TrapG was selectively trapped on purified beta-glucuronidase or beta-glucuronidase-expressing CT26 cells (CT26/m beta G) but not on bovine serum albumin or non-beta-glucuronidase-expressing CT26 cells used as controls. beta-glucuronidase-activated FITC-TrapG did not interfere with beta-glucuronidase activity and could label bystander proteins near beta-glucuronidase. Both FITC-TrapG and NIR-TrapG specifically imaged subcutaneous CT26/m beta G tumors, but only NIR-TrapG could image CT26/m beta G tumors transplanted deep in the liver. Thus NIR-TrapG may provide a valuable tool for visualizing beta-glucuronidase activity in vivo.

    FORMATION OF HYDROGEL IN THE PRESENCE OF PEROXIDASE AND LOW CONCENTRATION OF HYDROGEN PEROXIDE
    摘要:
    通过使用含有过氧化氢(H2O2)、辣根过氧化物酶(HRP)和一种包含交联酚基的聚合物的混合物来形成水凝胶的过程中,当H2O2的摩尔浓度限制在一定范围内,而HRP的浓度限制在阈值以上时,可以通过选择溶液中H2O2的摩尔浓度和HRP的浓度来独立调节或控制溶液中的凝胶化速率和水凝胶中的交联密度。公开了确定范围和阈值的方法。水凝胶可用于培养细胞,在这种情况下,可以选择H2O2的摩尔浓度来影响水凝胶中细胞的分化或生长速率。

The biological activities of the glycopeptide dendrimer conjugates were evaluated in HeLa tumor cells and non-transformed mouse embryonic fibroblasts (MEFs).
