Pinostilbene 是 Pterostilbene 的一种主要代谢物。Pinostilbene 对结肠癌细胞有抑制作用。
生物活性 | Pinostilbene is a major metabolite of Pterostilbene. Pinostilbene exhibits inhibitory effects on coloncancercells[1]. |
体外研究 (In Vitro) | Pinostilbene (0- 40 μM; 24 hours, 48 hours) does not cause significant inhibition on the growth of normal colon cells[1]. Pinostilbene (20 μM, 40 μM; 24 hours, 48 hours) causes a significant and dose-dependent increase in the percentage of cells in S phase in both HCT116 and HT29 cells compared to the control cells[1]. Pinostilbene at μM also induces a modest increase of cell population in G2/M phase in HT29 cells[1]. Pinostilbene(20 μM, 40 μM; 24 hours, 48 hours) modulates expression of key signaling proteins related to cell proliferation and apoptosis[1]. Pinostilbene also acts as a resveratrol methylated derivative and displays protective effects against 6-hydroxydopamine-induced neurotoxicity in SH-SY5Y cells[2].
Cell Viability Assay[1] Cell Line: | HCT116 cells, HT29 cells | Concentration: | 24 hours, 48 hours | Incubation Time: | 0-100 μM | Result: | Inhibited the growth of two human colon cancer cells. |
Apoptosis Analysis[1] Cell Line: | HCT116 cells, HT29 cells | Concentration: | 20 μM, 40 μM | Incubation Time: | 24 hours, 48 hours | Result: | Caused a significant and dose-dependent increase in the percentage of cells in S phase. |
Cell Viability Assay[1] Cell Line: | HCT116 cells | Concentration: | 20 μM,40 μM | Incubation Time: | 24 hours, 48 hours | Result: | Significantly increased the expression levels of p53, Bax, cleaved caspase-3, cleaved PARP and p21Cip1/Waf1, while decreased the expression levels of cyclin E and p-Rb. |
