• Beschreibung

  Testosterone (Item No.15645) is an analytical reference material categorized as an anabolic androgenic steroid. Testosterone is an endogenous metabolite of androstenedione (Item Nos. ISO60161 | 15874) and estradiol (Item Nos. ISO60155 | 10006315). Anabolic steroids, including testosterone, have been used to enhance physical performance in athletes. Testosterone is regulated as a Schedule III compound in the United States. This product is intended for research and forensic applications.

• Verwenden

  androgen, antineoplastic

• Verwenden

  Testosterone secreted by the testis is converted to dihydrotestosterone in the target tissues where it appears to mediate many of the biological actions of testosterone. Androgens direct the development of the male phenotype during embryogenesis and at puberty.

• Verwenden

  Testosterone, Principal hormone of the testes, produced by the interstitial cells. Major circulating androgen; converted by 5α-reductase in androgen-dependent target tissues to 5α-dehydrotestosterone which is required for normal male sexual differentiation. Also converted by aromatization to Estradiol. Testerone is a controlled substance (anabolic steroid). Androgen.

• Verwenden

  Rivastigmine metabolite

• Definition

  ChEBI: An androstanoid having 17beta-hydroxy and 3-oxo groups, together with unsaturation at C-41C-5..

• Allgemeine Beschreibung

  Testosterone, 17β-hydroxyandrost-4-en-3-one, is a naturally occurring androgen in men. Inwomen, it mainly serves as a biosynthetic precursor to estradiolbut also has other hormonal effects. It is rapidly metabolizedto relatively inactive 17-ones, however,preventing significant oral activity. Testosterone is availablein a transdermal delivery system (patch), a gel formulation, abuccal system, and as implantable pellets.

• Hazard

  A confirmed carcinogen.

• Health Hazard

  Controls secondary male sex characteristics Maintains functional competence of male reproductive ducts and glands
  Increases protein anabolism; maintains spermatogenesis; inhibits follotropin
  Increases male sex behavior; increases closure of epiphyseal plates

• Biologische Aktivität

  Endogenous androgen receptor agonist.

• Biochem/physiol Actions

  Testosterone secreted by the testis is converted to dihydrotestosterone in the target tissues where it appears to mediate many of the biological actions of testosterone. Androgens direct the development of the male phenotype during embryogenesis and at puberty.

• Sicherheitsprofil

  Confirmed carcinogen with experimental neoplastigenic and teratogenic data. Poison by intraperitoneal route. Human teratogenic effects by unspecified route: developmental abnormalities of the urogenital system. Experimental reproductive effects. Human mutation data reported. Workers engaged in manufacture and packagmg have shown effects from this hormone, e.g., enlargement of the breasts in male workers. A promoter. When heated to decomposition it emits acrid smoke and irritating fumes. Used as a drug for the treatment of hypogonadism and metastatic breast cancer.

• Synthese

  Testosterone, 17|?-hydroxyandrost-4-ene-3-one (29.1.5), is made in a number of ways from different substances, including cholesterol, although it is most often made from androstenolone acetate. In order to do this, the keto-group at C17 of the steroid system of androstenolone acetate is reduced to a hydroxyl group by either sodium borohydride, lithium aluminum hydride, or hydrogen over Raney nickel, all of which result in a 17|?-hydroxy compound. In the given example, reduction by sodium borohydride or hydrogen over Raney nickel leads to the formation of 3|?-acetoxy-5-androsten-17|?-ol (29.1.1). The hydroxyl group resulting from reduction then undergoes acylation by benzoyl chloride in pyridine, which forms a diester (29.1.2). After that, taking into consideration the differences in the acidic region of the two ester groups present in the molecule as well as the long-known fact that 17-hydroxy-group ester derivatives are harder to hydrolyze than 3-hydroxy-group ester derivatives, the acetyl protection of the hydroxyl group at C3 is removed by selective hydrolysis using potassium hydroxide in ethanol, and the resulting alcohol (29.1.3) is oxidized to a ketone (29.1.4) by aluminum isopropylate in the presence of cyclohexanone as a hydrogen acceptor, during which isomerization of the double bond from position C5¨CC6 to C4¨CC5 simultaneously takes place. Subsequent hydrolysis of the remaining ester region of the molecule using an alkali gives the desired testosterone (29.1.5) . When necessary to convert this into the corresponding ester (propionate, enantate, cypionate, and a few other testosterone esters), the necessary acylation can be accomplished.

  

• läuterung methode

  Crystallise testosterone from aqueous acetone, hexane or isoPrOH. The long needles that separated from EtOH/AcOH were used for X-ray crystallography [Roberts et al. J Chem Soc Perkin Trans II 1978 1973.] The acetate [1045-69-8] crystallises from MeOH or aqueous Me2CO, with m 140-141o and [] D 20 +87.8o (c 1, EtOH). [Ruzicka et al. Helv Chim Acta 18 1478 1935 and 19 99, 842 1936, Beilstein 8 IV 974.]
