• Beschreibung

  Progesterone, along with pregnenolone, is the biosynthetic precursor of all other steroid hormones. Progesterone is synthesized from cholesterol by the sequential action of desmolase in the mitochondria, which produces pregnenolone, followed by Δ^4,5-isomerase in the outer mitochondrial membrane and smooth endoplasmic reticulum of steroid-secreting cells. Progesterone activates the human progesterone receptor with an EC₅₀ value of 0.5 nM.

• Chemische Eigenschaften

  White powder. Melting point 121°C. Stable in air. Insoluble in water. A female sex hormone. Low toxicity.

• Occurrence

  Colchicum luteum also yields this alkaloid.

• Verwenden

  Steroid hormone produced by the corpus luteum. Induces maturation and secretory activity of the uterine endothelium; suppresses ovulation. Progesterone is implicated in the etiology of breast cancer.This compound is a contaminant of emerging concern (CECs).

• Verwenden

  Progesterone is used as a contraceptive, for amenorrhea, for premenopausal syndrome, infertility, incomplete pregnancies, and anovulatory uterine bleeding.

• Definition

  ChEBI: Progesterone is a C21-steroid hormone in which a pregnane skeleton carries oxo substituents at positions 3 and 20 and is unsaturated at C(4)-C(5). As a hormone, it is involved in the female menstrual cycle, pregnancy and embryogenesis of humans and other species. It has a role as a contraceptive drug, a progestin, a progesterone receptor agonist, a human metabolite and a mouse metabolite. It is a 20-oxo steroid, a 3-oxo-Delta(4) steroid and a C21-steroid hormone. It derives from a hydride of a pregnane.

• Trademarks

  Crinone (Columbia); Prometrium (Unimed).

• Biologische Funktion

  Progesterone is a hormone, produced primarily by the corpus luteum of the ovary but also by the placenta, that prepares the inner lining of the uterus for implantation ofa fertilized egg cell. If implantation fails, the corpus luteum degenerates and progesterone production ceases accordingly. If implantation occurs,the corpus luteum continues to secrete progesterone, under the influence of luteinizing hormone and prolactin, for several months of pregnancy,by which time the placenta has taken over this function. Duringpregnancy, progesterone maintains the constitution of the uterus and prevents further release of eggs from the ovary. Small amounts of progesterone are produced by the testes.

• Allgemeine Beschreibung

  Progesterone, pregn-4-en-3,20-dione, is so rapidly metabolized that it is not particularlyeffective orally, being only one twelfth as active as intramuscularly.An oral formulation of micronized progesterone(Prometrium) is available. Progesterone given intramuscularlycan be very irritating. A vaginal gel containing 4% or8% progesterone offers an alternative dosage form.Progesterone was originally obtained from animal ovariesbut is now prepared synthetically from plant sterol precursors.The discovery of 19-nortestosterones with progesteroneactivity made synthetically modified progestins of tremendoustherapeutic importance.
  Progesterone (and all other steroid 4-ene-3-ones) is lightsensitive and should be protected from light.

• Air & Water Reaktionen

  Insoluble in water.

• Reaktivität anzeigen

  Progesterone is sensitive to light .

• Hazard

  A carcinogen (OSHA).

• Health Hazard

  ACUTE/CHRONIC HAZARDS: Progesterone may be absorbed through the skin.

• Brandgefahr

  Flash point data for Progesterone are not available; however, Progesterone is probably combustible.

• Biologische Aktivität

  Endogenous progesterone receptor (PR) agonist (EC 50 = 0.5 nM).

• Biochem/physiol Actions

  Induces maturation and secretory activity of the uterine endothelium; suppresses ovulation. Progesterone is implicated in the etiology of breast cancer.

• Pharmakologie

  During the second half of the menstrual cycle, progesterone promotes glandular growth in the endometrium, hyperemia of the uterus, thickening of the endometrium in preparation for implantation of a fertilized egg, and reduces the excitability of the uterus during pregnancy, inhibiting its activity and relaxing smooth muscles , allowing the embryo to grow safely. Under the joint action of estrogen, progesterone promotes the development of breast lobules and glands, so that the breasts can fully develop and prepare for lactation. Progesterone closes the cervix, reduces and thickens the mucus, and makes it difficult for sperm to penetrate; in large doses, it inhibits the secretion of pituitary gonadotropin through a negative feedback effect on the hypothalamus, resulting in the inhibition of ovulation. After ovulation, on the basis of the action of progesterone hormone, the endometrium continues to thicken and hyperemia, the glands proliferate and branch, from the proliferative phase to the secretory phase, which is conducive to the implantation and embryonic development of pregnant eggs. Progesterone inhibits uterine contractions and reduces the sensitivity of the uterus to oxytocin, allowing the fetus to grow safely. Progesterone competes against aldosterone, thereby promoting Na and Cl excretion and diuresis. Progesterone can slightly increase body temperature in normal women, so the basal body temperature in the luteal phase of the menstrual cycle is higher than that in the follicular phase.

  NTP 10th Report on Carcinogens. IARC Cancer Review: Animal Lirmted Evidence IMEMDT 21,491,79; Animal Sufficient Evidence IMEMDT 6,135,74. EPA Genetic Toxicology Program. Reported in EPA TSCA Inventory. SAFETY PROFILE: Confirmed carcinogen with experimental carcinogenic, neoplastigenic, tumorigenic, and teratogenic data. Poison by intravenous and intraperitoneal routes. Human teratogenic effects by ingestion and parenteral routes: developmental abnormalities of the urogenital system. Human male reproductive effects by intramuscular route: changes in spermatogenesis, the prostate, seminal vesicle, Cowper's gland and accessory glands, impotence, and breast development. Human female reproductive effects by ingestion, parenteral, and intravaginal routes: ferthty changes; menstrual cycle changes and disorders; uterus, cervix, and vagina changes. Experimental reproductive effects. Human mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes.

• Synthese

  Progesterone, pregn-4-en-3,20-dione (28.3.1), is made by oxidizing pregnenolon with aluminum isopropylate in the presence of cyclohexanone as a proton acceptor (Oppenauer oxidation). Pregnenolon itself is made by subsequent oxidation and further cleavage of the side chain of stigmasterin, a sterin of plant origin that is isolated from soybeans.

  

• Carcinogenicity

  Progesterone is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
