Two New Phenylpropanoids and a Polyphenol with Anti‐Cervical Cancer Activity from Smilax china L.

Abstract Two novel phenylpropanoids (compounds 1 and 2 ) and 11 known compounds were isolated from Smilax china L. Their structures were determined by NMR (1D and 2D) and high‐resolution electrospray ionization mass spectrometry. Further, the cytotoxic activity of all the isolated compounds against HeLa, 4T1, and U251 tumor cells was evaluated using the cell counting kit‐8 assay, revealing that compound 13 showed significant cytotoxicity toward HeLa cells. Further investigations explored the impact of compound 13 on the mitochondrial membrane potential, concentration of reactive oxygen species, wound‐healing distance, and cell cycle of HeLa cells. Notably, compound 13 significantly decreased mitochondrial membrane potential, suppressed cell migration, and increased intracellular reactive oxygen species levels in HeLa cells. Furthermore, compound 13 inhibited HeLa cell‐cycle progression in the S phase. These findings indicate that compound 13 is a potential drug lead for the treatment of cervical cancer.
