    摘要: A composition, or article for inhibition of bone growth and resorption comprises an anti-inflammatory agent(s), optionally other agents and carriers, monomer(s), oligomer(s), polymer(s), salt(s), mixtures(s), dispersion(s) and/or blend(s) thereof, which composition, device, or implant upon polymer erosion releases a bone growth and/or bone resorption retarding, reducing or inhibiting amount of the agent(s). The monomers, oligomers and polymers, releasing active or activatable agent(s), have pre­selected properties such as molecular weight, flexibility, hardness, adhesiveness, and other valuable properties. The monomers, oligomers and polymers may be prepared by a process involving various alternative and sequential steps that allow the design a priori of products with specific characteristics. The composition, device, implant or dressing of this patent are suitable for retarding, reducing or inhibiting bone growth or bone resorption, comprising administering or applying to a subject's pre-selected site a bone growth or resorption reducing amount of the agent(s).

    摘要: The present invention relates to a conjugate that includes a nucleic acid ligand bound to a controlled release polymer system, a pharmaceutical composition that contains the conjugate, and methods of treatment using the conjugate. The controlled release polymer system includes an agent such as a therapeutic, diagnostic, prognostic, or prophylactic agent. The nucleic acid ligand that is bound to the controlled release polymer system, binds selectively to a target, such as a cell surface antigen, and thereby delivers the controlled release polymer system to the target.

    摘要: Provided herein are water-soluble prodrugs. The prodrugs of the invention comprise a water-soluble polymer having three or more arms, at least three of which are covalently attached to an active agent, e.g., a small molecule. The conjugates of the invention provided an optimal balance of polymer size and structure for achieving improved drug loading, since the conjugates of the invention possess three or more active agents releasably attached to a multi-armed water soluble polymer. The prodrugs of the invention are therapeutically effective, and exhibit improved properties in-vivo when compared to unmodified parent drug.
