2-Methoxyestradiol (2-MeOE2)使微管解聚,且抑制HIF-1α核积累和HIF转录活性。Phase 2。A disruptor of microtubule function and HIF-1 inhibitor
最大吸收波长:286(EtOH) nm
Information
2-Methoxyestradiol (2-MeOE2) 2-Methoxyestradiol (2-MeOE2, NSC 659853, 2-ME2) depolymerizes microtubules and blocks HIF-1α nuclear accumulation and HIF-transcriptional activity. 2-Methoxyestradiol induces both autophagy and apoptosis in various carcinoge
In vitro
2-Methoxyestradiol exhibits the inhibitory activity of cellular proliferation in a breast carcinoma cell line MDA-MB-435 and an ovarian carcinoma cell line SK-OV-3 with IC50 of 1.38 μM and 1.79 μM, respectively. Furthermore, 2-Methoxyestradiol also inhibits cellular microtubule depolymerization in rat aortic smooth muscle A-10 cells with EC50 of 7.5 μM. 2-Methoxyestradiol inhibits proliferation of MCF-7 and BM cells with IC50 of 52 μM and 8 μM. In MDA-MB-231 cells, 2-Methoxyestradiol inhibits HIF-1-mediated transcriptional activation of target genes without affecting the transcription of HIF-1α itself. A recent study shows that 2-Methoxyestradiol (0.5 μM), blocks TGF-β3-induced expression of collagen (Col) type I(αI), Col III(αI), plasminogen activator inhibitor (PAI) 1, connective tissue growth factor (CTGF), and α-smooth muscle actin (α-SMA). Moreover, 2-Methoxyestradiol ameliorates TGF-β3-induced Smad2/3 phosphorylation and nuclear translocation, and inhibits TGF-β3-induced activation of the PI3K/Akt/mTOR pathway.
In vivo
In a 9L rat glioma (9L-V6R) rat model, 2-Methoxyestradiol significantly decreases HIF-1 activity and inhibits the tumor growth in a dose-dependent manner by 4-fold reduction for 60 mg/kg/day, and 23-fold reduction for 600 mg/kg/day, respectively.
