体外研究:
VS 8 (Compound VS 8) (0.01-100 μM, 24 h) shows potent anti-proliferative activity against MCF-7, MDA-MB-231, Hep G2, and HUVECs cells.VS 8 induces early apoptosis in MDA-MB-231 (1413 nM, 72 h), Hep G2 (257.80 nM, 24 h), and HUVECs (1954 nM, 24 h) cells.VS 8 is shown to be a pro-oxidant molecule that enhances the ROS level in Hep G2 cells.VS 8 inhibits wound healing and migration of MCF-7 cancer cells.VS 8 downregulates human vascular endothelial growth factor (hVEGF) and hVEGFR-2 expression in HUVECs.VS 8 (257.80 nM, 48 h) arrests cell cycle at ‘G0/G1’ and ‘S’ phase in CD44+ and CD133+ CSCs, respectively.VS 8 inhibits TGF-β-induced epithelial-mesenchymal transition (EMT) in hepatocellular carcinoma by the upregulation of E-cadherin and the suppression of vimentin and SNAIL.
