  • Patent number: 6800273
    Abstract: The present invention describes novel compounds of the formula: (Q)d—Ln—Ch, useful for the diagnosis and treatment of cancer, methods of imaging tumors in a patient, and methods of treating cancer in a patient. The present invention also provides novel compounds useful for monitoring therapeutic angiogenesis treatment and destruction of new angiogenic vasculature. The pharmaceuticals are comprised of a targeting moiety that binds to a receptor that is upregulated during angiogenesis, an optional linking group, and a therapeutically effective radioisotope or diagnostically effective imageable moiety. The imageable moiety is a gamma ray or positron emitting radioisotope, a magnetic resonance imaging contrast agent, an X-ray contrast agent, or an ultrasound contrast agent.

  • Patent number: 5601800
    Abstract: A class of diagnostic and therapeutic compounds derived from phosphinimines that include ligands containing either a single phosphinimine functionality or both a phosphinimine group and a phosphine or arsine group, or an aminato group, or a second phosphinimine moiety. These phosphinimine ligands are complexed to early transition metal radionuclides (e.g. .sup.99m Tc or .sup.186 Re/.sup.188 Re) or late transition metals (e.g., .sup.105 Rh or .sup.109 Pd). The complexes with these metals .sup.186 Re/.sup.188 Re, .sup.99m Tc and .sup.109 Pd exhibit a high in vitro and high in vivo stability. The complexes are formed in high yields and can be neutral or charged. These ligands can also be used to form stable compounds with paramagnetic transition metals (e.g. Fe and Mn) for potential use as MRI contrast agents. Applications for the use of ligands and making the ligands are also disclosed.
