Abstract |
Purpose |
Co-delivery of two or more drugs into the same cancer cells or tissues in the same nanocarriers provides a new paradigm in cancer treatment. In this study, two kinds of nanocarriers: lipid-polymer hybrid nanoparticles (LPNs) and polymeric nanoparticles (PNPs) were constructed and compared for co-delivery of cisplatin (DDP) and curcumin (CUR).
Methods |
DDP and CUR loaded LPNs (D/C/LPNs) and PNPs (D/C/PNPs) were prepared. Two kinds of nanocarriers were characterized in terms of particle size, zeta potential, drug encapsulation efficiency (EE), and drug release. Their in vitro cytotoxicity and in vivo anti-tumor efficacy was studied on human cervix adenocarcinoma cell line (HeLa cells) and mice bearing cervical cancer model.
Results |
Compared with D/C/PNPs, D/C/LPNs showed significantly higher cytotoxicity in vitro. D/C/LPNs also displayed the best antitumor activity than other formulations tested in vivo.
Conclusions |
The results demonstrated that LPNs could improve the anticancer efficacy of drugs to higher levels than PNPs and free drugs, thus could serve as an effective drug system for targeted and synergistic co-delivery nanomedicine for cervical cancer chemotherapy.
