  • Platinum and palladium complexes
    Patent number: 4673754
    Abstract: Compositions of matter are provided wherein cis-platinum (II) and cis-palladium (II) moieties having amine substituents are bonded to anionic macromolecular entities. These compositions of matter may have improved solubility in the plasma and are effective antitrypanosomal and antitumor agents in mammals. Alternatively, the compositions of matter may be insoluble in water and particularly adapted for in situ implantation into tumerous masses.
    Type: Grant
    Filed: March 21, 1986
