  • Patent number: 5460807
    Abstract: The oligomers of the present invention are polyureas or polyamides having a number average molecular weight of <10,000. These oligomers are water-soluble, have a rigid backbone with a predictable anion spacing, and are pharmaceutically-acceptable. The oligomers are useful for inhibiting the proliferation of smooth muscle cell.
