(In Vitro) | 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[1].
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[1].
VS 8 is shown to be a pro-oxidant molecule that enhances the ROS level in Hep G2 cells[1].
VS 8 inhibits wound healing and migration of MCF-7 cancer cells[1].
VS 8 downregulates human vascular endothelial growth factor (hVEGF) and hVEGFR-2 expression in HUVECs[1].
VS 8 (257.80 nM, 48 h) arrests cell cycle at ‘G0/G1’ and ‘S’ phase in CD44+ and CD133+ CSCs, respectively[1].
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[1].
Cell Proliferation Assay[1] | Cell Line: | MCF-7, MDA-MB-231, Hep G2, and HUVECs cells | | Concentration: | 0.01, 0.1, 1, 10, 50, and 100 μM | | Incubation Time: | 24 h | | Result: | Showed significantly potent anti-proliferative activity against all the selected cell lines in a dose-dependent manner, with IC50values of 953.30, 1413, 257.80, and 1954 nM against MCF-7, MDA-MB-231, Hep G2, and HUVECs cells. |
Apoptosis Analysis[1] | Cell Line: | MDA-MB-231, Hep G2, and HUVECs cells | | Concentration: | 1413, 257.80, and 1954 nM for MDA-MB-231, Hep G2, and HUVECs cells, respectively. | | Incubation Time: | 72 h for MDA-MB-231 cells; 24 h for Hep G2 and HUVECs cells | | Result: | Resulted in high population of early apoptotic MDA-MB-231 cells (68.34 ± 0.18%). A significant increase in % apoptotic index (~86.66%) was observed in Hep G2 cells. The percentage of early apoptotic cells were found to be ~37.53% in HUVECs cells. |
Cell Cycle Analysis[1] | Cell Line: | CD44+ and CD133+ CSCs isolated from Hep G2 cells | | Concentration: | 257.80 nM | | Incubation Time: | 48 h | | Result: | Arrested cell cycle at ‘G0/G1’ and ‘S’ phase in CD44+ and CD133+ CSCs, respectively. |
