Methylstat is a novel and potent inhibitor of the Jumonji C domain-containing histone trimethyl demethylases (JHDMs) with anti-proliferative activity and low cytotoxicity. It induces apoptosis and cell cycle arrest at G0/G1 phase.
| ln Vitro |
Mmethylstat is non-cytotoxic to HUVEC at 1-2 µM and exhibits anti-proliferative action at 0-5 µM over 48 and 72 hours [1]. In the G0/G1 phase, mmethylstat (0, 1, 2 µM; 48 hours) dose-dependently promotes cell cycle arrest [1]. Mmethylstat (0, 1, 2 µM; 48 hours) inhibits the protein levels of cyclinD1, but enhances the expression of p53 mRNA, H3K27 methylation, and the accumulation of p53 and p21 [1]. Mmethylstat (0, 1, 2 µM) suppresses capillary formation during CAM (chick chorioallantoic membrane) growth and shows anti-angiogenic activity produced by VEGF, bFGF, and TNF-α in HUVEC cells. No symptoms of bleeding or thrombosis were seen. 1]. Mmethylstat dramatically promoted apoptosis in ARH77 and U266 cells (2.1, 4.2 mM for ARH77 cells, and 1.1, 2.2 mM for U266 cells; 72 hours) [2].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
