Drug entrapment efficiency, drug-loading capacity, and release properties in vitro were tested. The in vitro growth inhibition activity, cellular uptake efficiency, and cell apoptosis of FA-modified CUR LPs were also investigated by a cervical cancer HeLa cell model.Results: The optimized distearoyl-l-a-phosphatidylethanolamine (DSPE)-PEG2000-FA-LPs/CUR formed spherical vesicles of nanometer sizes and had particle sizes of 112.3±4.6 nm, polydispersity index of 0.19±0.03, and zeta potential of −15.3±1.4 mV. In addition, the EE% and DL% of (DSPE)-PEG2000-FA-LPs/CUR were 87.6% and 7.9%, respectively. Compared with the free drug, FA-modified CUR LPs had sustained-release properties in vitro. In vivo, a strong green fluorescence was observed in the cytoplasmic region after incubation of (DSPE)-PEG2000-FA-LPs/CUR for 2 hrs.Conclusion: (DSPE)-PEG2000-FA-LPs/CUR showed a superior antiproliferative effect on HeLa cells and had a better antitumor effect in vivo than the non-modified LPs. These results indicated that (DSPE)-PEG2000-FA-LPs/CUR was a promising candidate for antitumor drug delivery.Keywords: curcumin, folic acid, liposome, release, cell uptake, antiproliferative, antitumor study, HeLa
