Metarrestin
Based on 1 Customer Validation
Metarrestin (ML246) is an orally active, first-in-class and specific perinucleolar compartment inhibitor. Metarrestin disrupts the nucleolar structure and inhibits RNA polymerase (Pol) I transcription, at least in part by interacting with the translation elongation factor eEF1A2. Metarrestin blocks metastatic development and extends survival in mouse cancer models.

Metarrestin (ML246) disrupts perinucleolar compartments in PC3M-GFP-PTB cells with an IC50 of 0.39 μM[2].
Metarrestin (1 μM; 24 hours) reduces perinucleolar compartment prevalence in different human cancer cell lines. Metarrestin impacts cell growth in cancer cell line PC3M but not in normal fibroblasts (GM02153)[2].
Metarrestin (0.6 μM; 24 hours) effectively blocks the invasion of PC3M and PANC1 cells[2].
Metarrestin (1 μM; 24 hours) does not significantly change the amounts of Pol I large subunit RPA194 and UBF in the three cell lines, PANC1, PC3M, and HeLa. Metarrestin shows a substantial reduction of 5’ETS RNA in cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Metarrestin (drug-infused chow; 10 mg/kg; 70 ppm) extends survival in the NSG PANC1 pancreatic cancer metastasis mice model[2].
Metarrestin (5, 25 mg/kg; ip; for 4 additional week) reduces metastasis of prostate cancer (PC3M) and growth of metastatic breast cancer PDX mice models[2].
Metarrestin (5 and 25 mg/kg; IP) has a half-life of 4.6 to 5.5 hours[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- 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 (4.38 mM); Suspended solution; Need ultrasonic
