  • Publication number: 20240159744
    Abstract: The present disclosure relates to a cancer cell-specific complex for targeting cancer. The complex for targeting cancer according to the present disclosure includes EGF, but is affected more by lysosomal activity rather than the EGFR signaling pathway, and thus can overcome the shortcomings of the existing EGF therapy-based diagnostic and therapeutic compositions and provide successfully personalized and improved effects of treating, preventing and alleviating cancer. A diagnostic composition according to the present disclosure enables the prediction of the anticancer performance of a therapeutic composition of the present disclosure in a subject, and thus enables anticancer treatment to be designed stably.

  • Patent number: 11618916
    Abstract: A probe for measuring the activity of caspase-1 according to the present disclosure can specifically image cells or tissues where inflammatory response is induced because it is cleaved by reacting specifically with the active caspase-1 enzyme in vivo and in vitro and re-emits fluorescence. The probe for measuring the activity of caspase-1 can be used for various purposes, such as for imaging of cells or tissues where inflammatory response is induced, as a drug carrier, for screening of a drug inhibiting inflammatory response, etc. The probe for measuring the activity of caspase-1 is applicable both in vivo and in vitro, and can be used for various applications such as high-throughput screening for new drug development, early diagnosis of diseases, etc.

  • Patent number: 10610602
    Abstract: Disclosed is a drug conjugate as a prodrug that is degraded by cathepsin B specifically expressed in tumor tissues to release doxorubicin. The drug conjugate can form self-assembled nanoparticles. In addition, the drug conjugate specifically responds to and is activated in tumor cells. Therefore, the use of the drug conjugate eliminates the incidence of side effects (for example, cell damage and apoptosis) during the course of cancer prevention or treatment.
