• Beschreibung

  Aurothioglucose is highly water soluble, and its aqueous solutions decompose on long standing. It therefore is available as a suspension in sesame oil. Gold content is approximately 50%. Following IM injection, it is highly protein bound (95%), and peak plasma levels are achieved within 2 to 6 hours. Following a single 50-mg dose, the biological half-life ranges from 3 to 27 days, but following successive weekly doses, the half-life increases to 14 to 40 days after the third dose. The therapeutic effect does not correlate with serum plasma gold levels but appears to depend on total accumulated gold. Aurothioglucose is indicated for the adjunctive treatment of adult and juvenile rheumatoid arthritis.

• History

  In 1927, aurothioglucose was found to relieve joint pain when used to treat bacterial endocarditis. The area of chrysotherapy had begun. Subsequent investigations led to an extensive study of gold compounds in Great Britain by the Empire Rheumatism Council, which reported in 1961 that sodium aurothiomalate was effective in slowing the development of progressive joint diseases. Both aurothioglucose and sodium aurothiomalate are orally ineffective and are administered by IM injection. In 1985, the first orally effective gold compound for arthritis, auranofin, was introduced in the United States. Several other gold compounds have been evaluated clinically but do not appear to offer advantages in terms of efficacy or toxicity.

• Verwenden

  Aurothioglucose hydrate has been used in redox stress survival assay in human cell lines and for inducing obese phenotype in mice.

• Verwenden

  To produce obesity in experimental animals.

• Trademarks

  Solganal (Schering, USA, Yugoslavia), Aureotan (BYK Gulden, Germany).

• Biochem/physiol Actions

  Aurothioglucose, a gold compound used clinically to treat rheumatoid arthritis, has recently been found to be a potent PKCiota-Par6 interaction inhibitor, with an IC50 approximately 1 μM. Disruption of this interaction disrupts a rac1 signaling pathway that is required for transformed growth in non-small-cell lung cancer.

• Clinical Use

  Aurothioglucose is highly water soluble, and its aqueous solutions decompose on long standing. It therefore is available as a suspension in sesame oil. Gold content is approximately 50%. Following IM injection, it is highly protein bound (95%), and peak plasma levels are achieved within 2 to 6 hours.

Aurothioglucose is indicated for the adjunctive treatment of adult and juvenile rheumatoid arthritis.

• Sicherheitsprofil

  Confirmed carcinogen with experimental carcinogenic and neoplastigenic data. A deadly human poison by an unspecified route. An experimental poison by intramuscular route. Moderately toxic by subcutaneous and intravenous routes. Human systemic effects: nausea or vomiting, cholestatic jaundlce, and eye effects. An experimental teratogen. Other experimental reproductive effects. See also GOLD COMPOUNDS. When heated to decomposition it emits very toxic fumes of SOx. Used to treat rheumatoid arthritis.

• Synthese

  Synthesis: gold thioglucose is prepared by adding a solution of gold bromide to an aqueous solution of thioglucose that contains sulfur dioxide. After heating, the product is precipitated by the addition of ethanol.
  

• läuterung methode

  Purify it by dissolving it in H2O (0.05g in 1mL) and precipitating it by adding EtOH. It yields yellow crystals with a slight mercaptan odour. It decomposes slowly in H2O, and is soluble in propylene glycol but insoluble in EtOH and other common organic solvents. [Caterson & Taylor FEBS Lett 98 351 1979, Cooney et al. Biochem J 259 651 1989.]

• Dosage

  Aurothioglucose is an antirheumatic used to treat active progressing rheumatoid arthritis and nondisseminated lupus erythematosus. The drug is administered at weekly intervals by intramuscular injection (10 mg, 25 mg, then 50 mg) until 800 mg to 1 g has been given. If improvement takes place, the drug is then administered at levels that balance the urinary excretion of gold. During this maintenance therapy the interval between injections is lengthened to 3 – 4 weeks.
