General description

Mifepristone, a synthetic steroid, can be utilized for the management of Cushing′s syndrome and uterine leiomyomas. At low doses, it selectively antagonizes progesterone by binding to the intracellular progesterone receptor. At higher doses, mifepristone blocks cortisol at the glucocorticoid receptor, affecting the hypothalamic-pituitary-adrenal axis and leading to increased circulating cortisol, thereby controlling hyperglycemia in some patients. Additionally, mifepristone has a higher affinity for the glucocorticoid II receptor than for the glucocorticoid I receptor. In cases of pregnancy termination, mifepristone disrupts progesterone.[1]

Application

Mifepristone has been used:
  • to induce damage against the proliferative and secretory phase of endometrial stromal cells[2]
  • to establish a preterm birth (PTB) mice model in order to study the difference in cervical ripening mechanism between term and PTBs[3]
  • to activate geneswitch gal4 in flies[4]
  • to study the effects of sex steroids on prostaglandin secretion[5]

Biochem/physiol Actions

Mifepristone (RU-486) has activity as both a progesterone receptor antagonist and a glucocorticoid receptor antagonist.
Therefore, mifepristone is considered to be a potent abortifacient. It is also known to inhibit human chorionic gonadotropin.[6] Mifepristone results in decidual necrosis.[7]

    1. Which document(s) contains shelf-life or expiration date information for a given product?

      If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

    2. How do I get lot-specific information or a Certificate of Analysis?

      The lot specific COA document can be found by entering the lot number above under the "Documents" section.

    3. What is Mifepristone, Product M8046, soluble in?

      Mifepristone is soluble in ethanol at 50 mg/mL; heat may be required to dissolve the compound at this concentration.  It is also soluble in DMSO at 20 mg/mL.

    4. Can solutions of Mifepristone, Product M8046, be stored?

      Stock solutions of 1 mM mifepristone in ethanol can be stored at -20 °C. The top of the container should be sealed with Parafilm to prevent solvent evaporation. Solutions in ethanol, properly stored and handled, are probably good for several months (based on the structure of the compound), but we have no specific information on this.

    5. Where can I find information on usage of Mifepristone, Product M8046?

      The Sigma-Aldrich website listing has several cited articles with hyperlinks to the abstracts. These references can be found under the reference tab on the M8046 product webpage.

    6. How do I find price and availability?

      There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.
