摘要

Background: Doxorubicin (DOX) is a leading chemotherapeutic in cancer treatmentbecause of its high potency and broad spectrum. Liposomal doxorubicin (Doxil?) is the firstFDA-approved PEG-liposomes of DOX for the treatment of over 600,000 cancer patients, andit can overcome doxorubicin-induced cardiomyopathy and other side effects and prolong lifespan. The addition of MPEG2000-DSPE could elevate the total cost of cancer treatment.Objective: We intended to prepare a novel DOX liposome that was prepared with inexpensivematerials egg yolk lecithin and Kolliphor HS15, thus allowing it to be much cheaper for clinicalapplication.Methods: DOX liposomes were prepared using the combination of thin-film dispersion ultrasonicmethod and ammonium sulfate gradient method and the factors that influenced formulationquality were optimized. After formulation, particle size, entrapment efficiency, drug loading,stability, and pharmacokinetics were determined.Results: DOX liposomes were near-spherical morphology with the average size of 90 nm andpolydispersity index (PDI) of less than 0.30. The drug loading was up to 7.5%, and the entrapmentefficiency was over 80%. The pharmacokinetic studies showed that free DOX could beeasily removed and the blood concentration of free DOX group was significantly lower thanthat of DOX liposomes, which indicated that the novel DOX liposome had a certain sustainedreleaseeffect.Conclusion: In summary, DOX liposome is economical and easy-prepared with prolonged circulationtime.Lay Summary: Doxorubicin (DOX) is a leading chemotherapeutic in cancer treatment becauseof its high potency and broad spectrum. Liposomal doxorubicin (Doxil?) is the first FDAapprovedPEG-liposomes of DOX to treat over 600.000 cancer patients, overcoming doxorubicin-induced cardiomyopathy and other side effects and prolonging life span. The addition ofMPEG2000-DSPE could elevate the total cost of cancer treatment. We intend to prepare a novelDOX liposome prepared with inexpensive materials egg yolk lecithin and Kolliphor HS15, thusallowing it to be much cheaper for clinical use. The novel DOX liposome is economical andeasy-prepared with prolonged circulation time.
