    摘要: The present invention relates to a method for determining the modification conditions of a therapeutic agent comprising (1) assaying the biological activity of a first modified therapeutic agent after the first modified therapeutic agent has been administered to a subject; (2) assaying the biological activity of the first modified therapeutic agent after at least one booster dose of the first modified therapeutic agent has been administered to said subject (3) carrying out (1) and (2) with an additional modified therapeutic agent that has been modified differently than the first modified therapeutic agent, and (4) comparing the biological activity of the first modified therapeutic agent with the biological activity of the additional modified therapeutic agent. The present invention also relates to modified therapeutic agents.

    摘要: The present invention refers to a method for inducing tumor apoptosis by influencing the ROS (reactive oxygen species) signaling pathway in tumor cells. Increasing the level of ROS leads to the selective inactivation of a tumor cell catalase and subsequently to an apoptosis of these cells. The level of ROS can be increased by increasing the level of nitric oxide through inhibition of the enzymes nitric oxide dioxygenase or arginase.
    According to the present invention inhibitors of the nitric oxide dioxygenase or arginase can be used for the manufacture of a medicament for the treatment of cancer. The present invention further provides a method for identifying compounds which can be used for the treatment of cancer, wherein the method allows to specifically identify compounds which induce apoptosis through the ROS signaling pathway. The present invention also provides a kit for identifying compounds which induce tumor apoptosis by inactivating a catalase on the tumor cell surface.

    摘要: A creatine amidinohydrolase having the following physicochemical properties:

    Action: catalyzing the following reaction; creatine + H 2 O → sarcosine + urea
    Optimum temperature: about 40 - 50°C
    Optimum pH: pH about 8.0 - 9.0
    Heat stability: not more than about 50°C (pH 7.5, 30 min)
    Km value for creatine in a coupling assay using a sarcosine oxidase and a peroxidase: about 3.5 - 10.0 mM
    Molecular weight: about 43,000 (SDS-PAGE)
    Isoelectric point: about 3.5,
    a method for producing said enzyme, comprising culture of microorganism producing said enzyme, a method for the determination of creatine or creatinine in a sample using said enzyme, and a reagent therefor. According to the present invention, a creatine amidinohydrolase having a smaller Km value than that of the conventionally known creatine amidinohydrolase can be produced in an industrially large amount, and can be used as a routine reagent for clinical tests for determining creatine and creatinine in biological samples.
