  • Publication number: 20200308184
    Abstract: The present disclosure provides compounds comprising a tetrapyrrole (e.g., a tetrapyrrole group) linked via a linker to one or more ligands and uses of the compounds. The compounds may be used as imaging agents (e.g., MRI contrast agents) or as both imaging and therapeutic agents. The compounds may be used to treat individuals in need of treatment for a hyperproliferative disorder, such as, for example, malignancy. The present disclosure also provides kits comprising pharmaceutical preparations containing any one or any combination of the compounds described herein.

  • Patent number: 8133473
    Abstract: A compound comprising a chemical combination of a photodynamic tetra-pyrrolic compound with a plurality of radionuclide element atoms such that the compound may be used to enhance MR imaging and also be used as a photodynamic compound for use in photodynamic therapy to treat hyperproliferative tissue. The preferred compounds have the structural formula: where R1, R2, R2a R3, R3a R4, R5, R5a R6, R7, R7a, and R8 cumulatively contain at least two functional groups that will complex or combine with an MR imaging enhancing element or ion. The compound is intended to include such complexes and combinations and includes the use of such compounds for MR imaging and photodynamic therapy treatment of tumors and other hyperproliferative tissue.

  • Patent number: 7078014
    Abstract: A method for MR imaging that comprises conducting the MR imaging after injecting compositions that are chemical combination of porphyrins, chlorins, bacteriochlorins, and related tetra-pyrrolic compounds with radioactive elements such as Technetium99, Gadolinium, Indium111 and radioactive iodine. When the element can form cations, the compound is usually a chelate with the porphyrin or chlorin structure. When the element forms anions, the compound is usually a direct chemical combination of the radioactive element into the porphyrin or chlorin structure. The method uses the compounds of the invention for diagnostic imaging of hyperproliferative tissue such as tumors and new blood vessel growth as is associated with the wet form of age related macular degeneration and methods of making the compounds.
