19-Norpregna-4,9-diene-3,20-dione,11-[4-(dimethylamino)phenyl]-17-hydroxy-, (11b)-

Description:

19-Norpregna-4,9-diene-3,20-dione,11-[4-(dimethylamino)phenyl]-17-hydroxy-, (11b)-, commonly referred to by its CAS number 159811-51-5, is a synthetic steroid compound that exhibits characteristics typical of steroid hormones. It features a steroid backbone with modifications that include a dimethylamino group and a hydroxyl group, which can influence its biological activity and solubility. The presence of the 19-nor configuration indicates the absence of a methyl group at the C19 position, which can affect its receptor binding and metabolic stability. This compound may exhibit pharmacological properties, potentially acting as an anabolic agent or influencing hormonal pathways. Its structural modifications suggest that it could interact with androgen or progesterone receptors, making it of interest in both medicinal chemistry and pharmacology. As with many steroid derivatives, its synthesis and application would require careful consideration of its biological effects, potential therapeutic uses, and regulatory status.

Ulipristal acetate is a progesterone receptor modulator that prevents ovulation. It is used for the treatment of uterine fibroids and as an emergency contraceptive. This drug binds to the progesterone receptor, which leads to an inhibition of estrogen-dependent processes, such as endometrial proliferation and ovarian follicular development. Ulipristal acetate has been shown to be effective in premenopausal women with a body mass index (BMI) greater than or equal to 30 kg/m2. This drug also has a short half-life and is rapidly metabolized by glucuronidation in the liver. The concentration–time curve for ulipristal acetate is linear over the therapeutic dose range.
