Product Overview:
Mifepristone-d3 is intended for use as an internal standard for the quantification of mifepristone (Item No. 10006317) by GC- or LC-MS. Mifepristone is an antagonist of glucocorticoid, progesterone, and androgen receptors (Kis = 0.1, 0.64, and 0.65 nM, respectively).{41967,41968,40657} It is selective for these receptors over the mineralocorticoid receptor (MR), estrogen receptor α (ERα), and ERβ (Kis = 640, >200, and >750 nM, respectively).{41967} In cell-based assays, mifepristone inhibits alkaline phosphatase activity stimulated by the progesterone receptor agonist R5020 as well as reporter transcription stimulated by either dexamethasone (Item No. 11015) or R5020 (IC50s = 7, 5.9, and 1.3 nM, respectively).{40657} It also inhibits synthetic androgen R1881-stimulated reporter transcription in a concentration-dependent manner.{41968} Mifepristone (10 µM) inhibits growth of 4-OHT-resistant MCF-7 breast cancer cells in vitro.{12451} It also inhibits tumor growth in an SKOV3 ovarian cancer nude mouse xenograft model when administered at doses of 0.5 or 1 mg per day.{41969} Formulations containing mifepristone have been used for the induction of medical abortions.

Cayman Chemical's mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.

Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.

Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.

Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
