Candidate ID: R0196
Source ID: DB00684
Source Type: approved; investigational
Compound Type: small molecule
Compound Name: Tobramycin
Synonyms:
Molecular Formula: C18H37N5O9
SMILES: NC[C@H]1O[C@H](O[C@@H]2[C@@H](N)C[C@@H](N)[C@H](O[C@H]3O[C@H](CO)[C@@H](O)[C@H](N)[C@H]3O)[C@H]2O)[C@H](N)C[C@@H]1O
Structure:
DrugBank Description: An aminoglycoside, broad-spectrum antibiotic produced by Streptomyces tenebrarius. It is effective against gram-negative bacteria, especially the pseudomonas species. It is a 10% component of the antibiotic complex, nebramycin, produced by the same species.
CAS Number: 32986-56-4
Molecular Weight: 467.5145
DrugBank Indication: For the treatment of pseudomonas aeruginosa lung infections. Also being investigated for use in the treatment of sinus infections.
DrugBank Pharmacology: Tobramycin, an aminoglycoside antibiotic obtained from cultures of <i>Streptomyces tenebrarius</i>, is used in combination with other antibiotics to treat urinary tract infections, gynecologic infections, peritonitis, endocarditis, pneumonia, bacteremia and sepsis, respiratory infections including those associated with cystic fibrosis, osteomyelitis, and diabetic foot and other soft-tissue infections. It acts primarily by disrupting protein synthesis, leading to altered cell membrane permeability, progressive disruption of the cell envelope, and eventual cell death. Tobramycin has in vitro activity against a wide range of gram-negative organisms including <em>Pseudomonas aeruginosa</em>.
DrugBank MoA: Tobramycin binds irreversibly to one of two aminoglycoside binding sites on the 30 S ribosomal subunit, inhibiting bacterial protein synthesis. Tobramycin may also destabilize bacterial memebrane by binding to 16 S 16 S r-RNA. An active transport mechanism for aminoglycoside uptake is necessary in the bacteria in order to attain a significant intracellular concentration of tobramycin.
Targets: 16S ribosomal RNA; 23S ribosomal RNA; Bacterial outer membrane; NA
