  • Publication number: 20200330625
    Abstract: The present invention describes new compounds that are useful for image-guided surgery and photodynamic therapy. In particular the compounds may be targeted to the nucleus or the mitochondria after compounds were delivered to diseased tissues such as cancer using a ligand that target receptor that express on the diseased tissue and followed by receptor mediated endocytosis and provide effective activity against cancer cells as well as other disorders. Methods and compositions for use of the same are described.
