ABSTRACT
Piperlongumine (PL) is a biologically active alkaloid derived from peppers, has significant cytotoxic effects on cancer with no cytotoxicity. This study used NabTM technology to prepare PL albumin nanoparticles (PL-BSA-NPs) to improve water solubility and bioavailability. We carried out a pharmacological evaluation of the PL-BSA-NPs. The morphological profile of the PL-BSA-NPs was relatively uniform, with an average particle size of approximately 210 nm, with drug load of 2.1% and encapsulation rate of 87.6%. PL-BSA-NPs were stable for 4 weeks when stored at 4°C. In vitro release behavior of the PL-BSA-NPs showed a sustained release, with a cumulative release of 67.24% in approximately 24 hours. The pharmacokinetic properties of PL-BSA-NPs were shown that PL-BSA-NPs could maintain a certain level of blood drug concentration for a long time, thus demonstrating the sustained release and increased bioavailability of PL. Finally, we investigated the in vitro antitumor activity of the PL-BSA-NPs and found that PL can significantly inhibit HepG2 cell proliferation, and that PL-BSA-NPs enhanced the inhibitory effect of PL on this proliferative effect. Thus, we concluded that PL can destroy liver cancer cells by increasing ROS levels. These results suggested that PL-BSA-NPs show promising potential as a targeted anti-tumor drug.
