Polyvinyl butyral DMN-conjugates for the controlled release of singlet oxygen in medical and antimicrobial applications
Damir Posavec, Rainer Muller, Udo Bogner, Gunther Bernhardt and Gunther Knor

    Covalent attachment of 1, 4-dimethylnaphthalene (DMN) based endoperoxide forming subunits to a polyvinyl butyral (PVB) backbone has been achieved. The functionalized polymer materials prepared and characterized here can serve as biocompatible carrier systems for studying cellular uptake, intermediate storage and delayed release of singlet oxygen, which opens up new doors for optimizing a variety of medical applications of photogenerated DMN-endoperoxides such as antiviral, antibacterial, antiplasmodial and antitumor activity.
Key Words
    dimethyl naphthalene; Polyvinyl butyral; endoperoxides; singlet oxygen; drug carriers
