We report the design of a platform for the delivery of hydrophobic drugs via a macromolecular prodrug approach combined with LbL-assembled polyelectrolyte multilayers. A hyaluronan ester prodrug of the chemotherapeutic drug paclitaxel has been synthesized. Conjugation of the drug to hyaluronan through a labile succinate ester did not inhibit its activity. Using quartz crystal microbalance, atomic force microscopy, and UV spectroscopy, we have shown that the presence of the hydrophobic paclitaxel moieties does not prohibit the layer-by-layer construction of the multilayers. Release of the drug from the paclitaxel-loaded multilayers upon hydrolysis of the ester linkage resulted in a drastic cell death. Application of this delivery platform to substrates such as colloids, biomedical implants, or vascular tissues may lead to new therapeutic strategies.
