【 摘 要 】

BackgroundThe problems associated with the poor water solubility of anticancer drugs are one of the most important challenges in achieving effective cancer therapy. The present study was designed to evaluate the effect of scutellarein on human colon cancer cells in vitro by using a target αvβ3 novel scutellarein (Scu)-loaded niosome nanoparticle (β-CD-CL-Scu-cRGD).Resultsβ-CD-CL-Scu-cRGD has a diameter of 140.2 nm and zeta potential of − 11.3 mV with constant physicochemical stability. The MTT assay showed both Scu and β-CD-CL-Scu-cRGD caused a decrease in cell proliferation and viability of LoVo, but β-CD-CL-Scu-cRGD showed better activity in vitro. Colony formation assay and flow cytometry assay showed that β-CD-CL-Scu-cRGD has a better effect on cell proliferation and apoptosis. In vivo, animal experimental results showed that β-CD-CL-Scu-cRGD can significantly inhibit tumor growth, and the bodyweight of mice decreases during the treatment of scutellarein and its derivatives. β-CD-CL-Scu-cRGD could inhibit the protein levels of Ki67 and αvβ3, thereby inhibiting tumor growth.ConclusionsAlthough further in vitro and in vivo studies are necessary, our results suggested that β-CD-CL-Scu-cRGD could be an outstanding carrier to deliver Scu for potential therapeutic approaches into colon cancer.
