• Beschreibung

  Streptomycin was found in the culture broth of Streptomyces griseus by S. A. Waksman of Rutgers University in 1944; it was the second antibiotic introduced clinically (after penicillin). This drug is a water soluble, basic substance having an aminoglycoside structure and showing strong activity against a wide range of gram-positive and gram-negative bacteria including Mycobacterium. Streptomycin is the first choice among antituberculotic antibiotics and has been used for the therapy of Spirochaeta and Treponema infections.

• Chemische Eigenschaften

  White to off-white powder

• Verwenden

  Antibiotic substance produced by aerobic fermentation. Antibacterial (tuberculostatic).

• Verwenden

  Streptomycin sulfate is a sulfate salt of streptomycin that is a protein synthesis inhibitor. Streptomycin is an antibiotic drug, the first of a class of drugs called aminoglycosides to be discovered, and was the first antibiotic remedy for tuberculosis.

• Verwenden

• Definition

  ChEBI: Streptomycin sulfate is an aminoglycoside sulfate salt. It is functionally related to a streptomycin.

  SYMPTOMS: Symptoms of exposure to Streptomycin sulfate include skin rashes, eosinophilia, blood dyscrasias, stomatitis, anaphylactic shock, pruritus, scaling, and fever.

• Brandgefahr

  Flash point data for Streptomycin sulfate are not available, however Streptomycin sulfate is probably combustible.

• Clinical Use

  Streptomycin sulfate is a white, odorless powder that is hygroscopicbut stable toward light and air. It is freely solublein water, forming solutions that are slightly acidic or nearlyneutral. It is very slightly soluble in alcohol and is insolublein most other organic solvents. Acid hydrolysis yields streptidineand streptobiosamine, the compound that is a combinationof L-streptose and N-methyl-L-glucosamine.
  Streptomycin acts as a triacidic base through the effectof its two strongly basic guanidino groups and the moreweakly basic methylamino group. Aqueous solutions maybe stored at room temperature for 1 week without any lossof potency, but they are most stable if the pH is between 4.5and 7.0. The solutions decompose if sterilized by heating,so sterile solutions are prepared by adding sterile distilledwater to the sterile powder. The early salts of streptomycincontained impurities that were difficult to remove andcaused a histamine-like reaction. By forming a complexwith calcium chloride, it was possible to free the streptomycinfrom these impurities and to obtain a product thatwas generally well tolerated.
  The organism that produces streptomycin, S. griseus, alsoproduces several other antibiotic compounds: hydroxystreptomycin,mannisidostreptomycin, and cycloheximide (q.v.).Of these, only cycloheximide has achieved importance as amedicinally useful substance. The term streptomycin A hasbeen used to refer to what is commonly called streptomycin,and mannisidostreptomycin has been called streptomycin B.Hydroxystreptomycin differs from streptomycin in having ahydroxyl group in place of one of the hydrogen atoms of thestreptose methyl group. Mannisidostreptomycin has a mannoseresidue attached in glycosidic linkage through the hydroxylgroup at C-4 of the N-methyl-L-glucosamine moiety.The work of Dyer et al. to establish the stereochemicalstructure of streptomycin has been completed, and confirmedwith the total synthesis of streptomycin and dihydrostreptomycinby Japanese scientists.

• Sicherheitsprofil

  Poison by ingestion and intravenous routes. Moderately toxic by subcutaneous route. An experimental teratogen. Human systemic effects by intraperitoneal route: flaccid paralysis without anesthesia, motor activity changes and pulmonary changes. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx and SOx. See also STREPTOMYCIN and SULFATES.

• läuterung methode

  The sulfate is recrystallised from H2O/EtOH, washed with a little EtOH, Et2O and dried in a vacuum. [UV and IR: Grove & Randall Antibiotics Monographs 2 163 1855, Heuser et al.

J Biol Chem 165 631 1946.] During protein synthesis it inhibits initiation and causes misreading of mRNA [Zierhut et al. Eur J Biochem 98 577 1979, Chandra & Gray Methods Enzymol 184 70 1990].
