Suppression of Metastasis and Angiogenesis by Taxifolin Ruthenium-p-cymene Loaded PLGA Nanoparticles in Lung Carcinoma.

Flavonoid-based organometallic complexes were revealed to be novel bioactive compounds. The taxifolin ruthenium-p-cymene nanoparticle (TaxRu-NPs) was produced in this study, and the toxicological assessment was done prior to in vivo chemotherapeutic research. Furthermore, the in vitro chemotherapeutic investigation used the A549 and NCI-H460 lung cancer cell lines. The in vitro study found that TaxRu-NPs induced apoptosis in lung cancer cells and hindered their ability to form colonies and migrate. The in vivo study showed that treatment with TaxRu-NPs restored the histological structure of a normal lung with less hyperplasia and lymphocytic infiltration. Furthermore, the treatment downregulated the angiogenic marker VEGF and the cell survival protein β-catenin and upregulated apoptotic markers like p53 and caspase-3. TaxRu-NPs treatment additionally raised the apoptotic index and decreased cancer cell growth. Finally, TaxRu-NPs effectively alleviate lung cancer by activating p53-mediated apoptosis and preventing angiogenesis and metastasis by decreasing the VEGF/β-catenin pathway.
