Abstract

We have developed a dual-function drug carrier, polyethylene glycol (PEG)-derivatized farnesylthiosalicylate (FTS). Here we report that incorporation of a drug-interactive motif (Fmoc) into PEG_5k-FTS₂ led to further improvement in both drug loading capacity and formulation stability. Doxorubicin (DOX) formulated in PEG_5k-Fmoc-FTS₂ showed sustained release kinetics slower than those of DOX loaded in PEG_5k-FTS₂. The maximum tolerated dose of DOX- or paclitaxel (PTX)-loaded PEG_5k-Fmoc-FTS₂ was significantly higher than that of the free drug. Pharmacokinetics and biodistribution studies showed that DOX/PEG_5k-Fmoc-FTS₂ mixed micelles were able to retain DOX in the bloodstream for a significant amount of time and efficiently deliver the drug to tumor sites. More importantly, drug (DOX or PTX)-loaded PEG_5k-Fmoc-FTS₂ led to superior antitumor activity over other treatments including drugs formulated in PEG_5k-FTS₂ in breast cancer and prostate cancer models. Our improved dual function carrier with a built-in drug-interactive motif represents a simple and effective system for targeted delivery of anticancer agents.
