| Hazard Information | Back Directory | [Uses]
2,4,3',5'-Tetramethoxystilbene acts as an inhibitor of human cytochrome P450 1B1 and has been seen to inhibit cell growth as well as induce apoptosis in cancer cells. | [Uses]
CYP1B1 is mainly an extrahepatic enzyme which oxidatively metabolizes both endogenous (steroids; eicosanoids) and exogenous xenobiotics such aspolyaromatic hydrocarbons. TMS is a potent and selective inhibitor of CYP1B1, with an IC50 of 6 nM. It is 50-fold selective for the inhibition of CYP1B1 versus CYP1A1, making it a useful tool to differentiate between various CYP450 families. In cultured human colon cancer cells, TMS induces apoptosis and inhibits cell growth with an IC50 of 0.8 μg/ml. | [Definition]
ChEBI:1-[2-(2,4-dimethoxyphenyl)ethenyl]-3,5-dimethoxybenzene is a stilbenoid. | [Biological Activity]
Potent, selective and competitive inhibitor of cytochrome P450 1B1, an enzyme overexpressed in certain tumors (IC 50 = 6 nM). 50- and 520-fold selective over P450 1A1 and 1A2 respectively. Inhibits cancer cell growth in vitro . | [storage]
