  • Patent number: 6664315
    Abstract: In the present invention, an inorganic reactant is, or reactants are, localized with respect to a dendritic polymer by physical constraint within or by a non-covalent conjugation to the dendritic polymer. The localized inorganic reactant or reactants is/are subsequently transformed to form a reaction product which is immobilized with respect to the dendritic polymer. This immobilization occurs on a nanoscopic scale as a consequence of the combined effects of structural, chemical and physical changes without having covalent bonds between the product(s) and the dendritic container and results in new compositions of matter called dendritic nanocomposites. The resulting nanocomposite material can be used to produce revolutionary products such as water soluble elemental metals, with specific applications including magnetic resonance imaging, catalytic, magnetic, optical, photolytic and electroactive applications.

  • Patent number: 6641999
    Abstract: This invention concerns a family of chimeric antibodies with high affinities to a high molecular weight, tumor-associated sialylated glycoprotein antigen (TAG-72) of human origin. These antibodies have (1) high affinity animal VH and VL sequences which mediate TAG-72 binding and (2) human CH and CL regions. They are thought to produce significantly fewer side-effects when administered to human patients by virtue of their human CH and CL antibody domains. The nucleotide and amino acid sequences of VH&agr;TAG VH, CC46 VH, CC49VH, CC83 VH, and CC92 VH, and CC49VL, CC83 VL, and CC92 VL idiotype sequences are disclosed, as well as in vivo methods of treatment and diagnostic assay using these chimeric antibodies.

  • Patent number: 6627772
    Abstract: Compounds represented by the formula wherein R and R1 independently represent H, —CH2CN or —CH2CO2X, with the proviso that R and R1 can not be both H or —CH2CO2X; and X represents hydrogen, an alkali metal or alkaline earth metal are disclosed. These compounds are useful as intermediate compounds in the preparation of N-[2-(carboxymethoxy)ethyl]-N-(carboxy-methyl)glycine. These intermediates can be formed by contacting 3-morpholinone with glycolonitrile under alkaline conditions to form an aminonitrile which can be hydrolyzed and contacted with additional glycolonitrile to form the nitrile intermediate which can be converted to N-[2-(carboxymethoxy)ethyl]-N-(carboxymethyl)glycine via hydrolysis.
