ABSTRACT:
The present invention relates to polymer-modified quinone-containing and carbonyl-containing therapeutic agents, including polymer-modified β-lapachone compounds, and methods of treating cancer by administering the polymer-modified therapeutic agents to a subject. Polymer-modification of therapeutic agents, such as β-lapachone compounds, provides effective transport of polymer-modified therapeutic agents to tumor cells or tumor tissues by exploiting the EPR effect in tumor tissues.
