  • Patent number: 6683163
    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 present invention further provides novel compounds useful for imaging atherosclerosis, restenosis, cardiac ischemia, and myocardial reperfusion injury. The present invention still further provides novel compounds useful for the treatment of rheumatoid arthritis. 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.

  • Publication number: 20040014950
    Abstract: New ligands and compositions with bridged bis-aromatic ligands are disclosed that catalyze the polymerization of monomers into polymers. These catalysts with metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene into isotactic polypropylene.

  • Patent number: 6677441
    Abstract: A cationic Group 3 or Lanthanide metal complex for coordination polymerization of olefins is disclosed. The precursor metal complex is stabilized by a monoanionic bidentate ancillary ligand and two monoanionic ligands. The ancillary ligand and the transition metal form a metallocycle having at least five primary atoms, counting any &pgr;-bound cyclopentadienyl group in the metallocycle as two primary atoms. Olefin polymerization is exemplified.

  • Publication number: 20040002420
    Abstract: Surprisingly stable olefin polymerization catalysts and co-catalysts formed from hydroxyaluminoxanes are revealed. In one embodiment of the invention, a solid composition of matter is formed from a hydroxyaluminoxane and a treating agent, whereby the rate of OH-decay for the solid composition is reduced as compared to that of the hydroxyaluminoxane. Gelatinous compositions of matter formed from hydroxyaluminoxane and having similar stability characteristics are also disclosed. Processes for converting a hydroxyaluminoxane into a such compositions of matter, supported catalysts formed from such co-catalyst compositions of matter, as well as methods of their use, are described.
