Abstract
Ampelopsins A and C are resveratrol oligostilbenes whose role in cancer development remains unknown. This study evaluated the antimetastatic and apoptosis-inducing properties of ampelopsins A and C in MDA-MB-231 cells. The IC50 values of ampelopsins A and C against MDA-MB-231 cells at 72 h were 38.75 ± 4.61 and 2.71 ± 0.21 μM, respectively. However, at 24 h, ampelopsins A and C decreased cell metastasis significantly. Among the 71 proteins present on the human phosphoreceptor tyrosin kinase array, ampelopsin C decreased the phosphorylated protein level of AXL, Dtk (TYRO3), EphA2, EphA6, Fyn, Hck, and SRMS. Additionally, antiproliferation effects of ampelopsin C were enhanced when combined with luteolin and chrysin compared to either two or a single agent in MDA-MB-231 cells. Overall, ampelopsins A and C extracted from Vitis thunbergii are both novel antimetastatic agents and potential therapeutic targets in patients with breast cancer.
