Long-circulating and liver-targeted nanoassemblies of cyclic phosphoryl N-dodecanoyl gemcitabine for the treatment of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a serious cancer with high mortality worldwide. Gemcitabine (GEM) is easily degraded in the circulation and has no tumor-targeted effect. In our previous research, an amphiphilic GEM derivative, cyclic phosphoryl N-dodecanoyl gemcitabine (CPDG) was prepared based on the techniques of HepDirect prodrug and self-assembled drug delivery systems (SADDS), which self-assembled into the stable nanoassemblies in water.
