  • Controlled release of thioamide moiety-containing therapeutic agents
    Patent number: 6468522
    Abstract: This invention pertains to disulfide-linked conjugates of therapeutic agents containing at least one thioamide group with polymer comprising at least one thiol group, so as to provide a controlled release pharmaceutical composition for administration to animals for the prophylaxis or treatment of various conditions or diseases. The therapeutic agent conjugate may comprise an inactive or weakly active prodrug form which may be converted into the original therapeutic compound by the natural action of reducing agents in vivo. The composition may comprise a mixture of polymers each with a different thioamide-containing agent attached, or a polymer conjugated with a mixture of thioamide-containing agents.
    Type: Grant
    Filed: July 21, 2000
    Date of Patent: October 22, 2002
    Assignees: University of Medicine and Dentistry of New Jersey, Rutgers, the State University of New Jersey
    Inventors: Stanley Stein, Guobao Zhang, Bo Qiu
  • Materials and processes for controlled release of thioamide moiety-containing therapeutic agents by linking to thiol-containing polymers

  • Multiple phase cross-linked compositions and uses thereof
    Publication number: 20020076443
    Abstract: The present invention is directed to pharmaceutical compositions, and method for preparing pharmaceutical compositions, comprising a cross-linked matrix physically entrapping at least one therapeutic agent. The matrix may comprise one or more phases in addition to an aqueous phase, such as a solid and/or oil phase. The matrix of the invention has at least one controlled release in-vivo kinetic profile, and may have additional profiles for the same agent. The matrix may also comprise more than one therapeutic agent, and each additional therapeutic agent may have one or more controlled release in-vivo kinetic profile.
