    Journal of the American Chemical Society, 2011
    Co-Authors: Jeremiah A Johnson, Alan O Burts, Yeonhee Lim, M G Finn, Jeffrey T Koberstein, Nicholas J Turro, David A Tirrell, Robert H Grubbs
    Abstract:

    The combination of highly efficient polymerizations with modular "click" coupling reactions has enabled the synthesis of a wide variety of novel nanoscopic structures. Here we demonstrate the facile synthesis of a new class of clickable, branched nanostructures, polyethylene glycol (PEG)-branch-azide bivalent-brush polymers, facilitated by "graft-through" ring-opening metathesis polymerization of a branched norbornene-PEG-chloride macromonomer followed by halide-azide exchange. The resulting bivalent-brush polymers possess azide groups at the core near a polynorbornene backbone with PEG chains extended into solution; the structure resembles a unimolecular micelle. We demonstrate copper-catalyzed azide-Alkyne cycloaddition (CuAAC) "click-to" coupling of a photocleavable doxorubicin (DOX)-Alkyne Derivative to the azide core. The CuAAC coupling was quantitative across a wide range of nanoscopic sizes (∼6-∼50 nm); UV photolysis of the resulting DOX-loaded materials yielded free DOX that was therapeutically effective against human cancer cells.
