Curcumin and baicalin loaded nanoliposomes for synergistic treatment of non-small cell lung cancer. - GreenMedInfo Summary

Currently, the treatment of patients with advanced non-small cell lung cancer (NSCLC) mainly relies on traditional chemotherapeutic drugs; however, most of them have limited therapeutic effects and high toxicity. Some natural products with good therapeutic efficacy and low toxicity and side effects are limited in clinical application due to their low solubility and bioavailability. In this study, a nanoliposome drug-carrying system (Lip-Cur/Ba) was developed for the co-delivery of curcumin (Cur) and baicalin (Ba) using the thin-film hydration method. In vitro experiments demonstrated that Lip-Cur/Ba had a strong killing effect on A549 cells, and the inhibitory effect of Lip-Cur/Ba on A549 cells was enhanced by 67.8% and 51.9% relative to that of the single-carrier system, which could reduce the use of a single-drug dose (Lip-Cur and Lip-Ba), delay the release rate of the drug and improve the bioavailability. In vivo experiments demonstrated the antitumor activity of Lip-Cur/Ba by intravitreal injection in BALB/c mice, and there were no obvious toxic side effects. This study provides a new idea for curcumin and baicalin to be used in the co-treatment of NSCLC by constructing a new vector.
