2-Methoxyestradiol
Based on 34 publication(s) in Google Scholar
2-Methoxyestradiol (2-ME2; NSC-659853) is an endogenous steroid metabolite generated from 17β-estradiol, possessing various activities such as antitumor and antiangiogenic effects. 2-Methoxyestradiol competitively binds to the colchicine-binding site of tubulin (tubulin), interfering with microtubule assembly dynamics. 2-Methoxyestradiol inhibits CYP1A1/CYP1B1, HIF-1α/2α, and superoxide dismutase, activates the JNK signaling pathway, elevates ROS levels, and induces cell cycle arrest and apoptosis (apoptosis). 2-Methoxyestradiol is used in cancer-related research, such as breast cancer, prostate cancer, and multiple myeloma.

体外実験
2-Methoxyestradiol has low ERα/ERβ binding affinity, and its antiproliferative/pro-apoptotic effects are independent of ER; its binding affinities for estrogen receptor α and β are 500-fold and 3200-fold lower than those of Estradiol (HY-B0141), respectively[1][2][4].
2-Methoxyestradiol competitively inhibits the binding of colchicine to tubulin and inhibits the polymerization of purified tubulin through the colchicine binding site[1][2][4].
2-Methoxyestradiol is demethylated to 2-hydroxyestradiol (HY-124489) by purified CYP1A1 and 1B1, and inhibits CYP1A1/1B1 in a concentration-dependent manner[2].
2-Methoxyestradiol (2ME2) binds to recombinant human ERα with a Ki of 21 nM and to ERβ with a Ki of 417 nM, showing low affinity for both estrogen receptor subtypes[3].
2-Methoxyestradiol is rapidly and extensively converted by liver microsomes from multiple species into catechol estrogens with estrogenic activity[4].
2-Methoxyestradiol exhibits antiproliferative activity against multiple human and murine tumor cell lines (IC50 = 0.08‑5 μM); moreover, it inhibits the growth of pancreatic cancer cell lines PaTu 8902, 8988t, and 8988s by 50-90% in a dose- and time-dependent manner[1][4].
2-Methoxyestradiol does not sustain the proliferation of estrogen-dependent MCF-7 cells[1].
2-Methoxyestradiol stimulates proliferation in ER-positive cells through CYP450-dependent metabolism and inhibits growth at higher concentrations[2].
2-Methoxyestradiol (HUVEC/MDA-MB-435 treated for 72 h; MCF7 treated for 8-10 days) exhibits antiproliferative activity in MDA-MB-435, HUVEC, and MCF7 cells, and this activity is not altered by the ER antagonist ICI 182,780 (HY-13636) and agonist E2, indicating that the antiproliferative effect is independent of ERα and ERβ[3].
2-Methoxyestradiol acts synergistically with radiotherapy, produces radiosensitizing effects in human lung cancer and breast cancer cell lines, and exhibits p53-dependent enhancement in human lung cancer cell lines[4].
2-Methoxyestradiol induces caspase-dependent apoptosis and G2-M phase arrest in SC-M1 and NUGC-3 gastric cancer cells[1].
2-Methoxyestradiol reduces aconitase activity by 53% in HL-60 human leukemia cells and supports increased superoxide production[1].
2-Methoxyestradiol disrupts microtubules and increases mitotic figures in V79, MCF-7, and endothelial cells, while inhibiting aromatase activity[1].
2-Methoxyestradiol (2 μM; 3 days) completely blocks bFGF-induced angiogenesis in the chick chorioallantoic membrane model[1].
2-Methoxyestradiol inhibits neovascularization in the rat aortic ring assay[1].
2-Methoxyestradiol (2.5 μM; 5 days) inhibits microvessel growth from rat aortic rings in collagen gels[4].
2-Methoxyestradiol inhibits the expression of HIF-1α/HIF-2α in cancer cell lines and the expression of HIF-1α in HUVECs, reducing VEGF transcription and secretion[2].
2-Methoxyestradiol upregulates DR5 and sensitizes tumor/endothelial cells to TRAIL, activating caspase 8/9 within 24 hours; in Ewing sarcoma cells, it induces H2O2-dependent JNK signaling and mitochondrial apoptosis[2].
2-Methoxyestradiol inhibits the proliferation of estrogen-independent MCF7, MDA-MB-435, and MDA-MB-231 cells with IC50 values of 1.5, 1.3, and 1.1 μM, respectively, and induces apoptosis independently of ER expression[3].
2-Methoxyestradiol upregulates DR5 and activates caspase 8/3 in endothelial cells and tumor cell lines, sensitizing them to TRAIL-induced apoptosis through a caspase-dependent mechanism[4].
2-Methoxyestradiol rapidly activates JNK and induces Bcl-2/Bcl-xL phosphorylation in multiple cancer cell lines; in wild-type p53 cells, it induces p53/p21 accumulation and regulates NF-κB in a p53 status-dependent manner in medulloblastoma and LNCaP cells[2].
2-Methoxyestradiol (24 h) increases superoxide in CLL cells, and higher basal superoxide levels correlate with greater sensitivity and loss of viability[2].
2-Methoxyestradiol inhibits the proliferation, adhesion, motility, and migration of Bcr-Abl-transformed mouse pre-B cells in a manner independent of superoxide generation[2].

- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (6.88 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (6.88 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
