Tobramycin BiologicalActivity

Description	Tobramycin is an aminoglycoside, broad-spectrum antibiotic produced by Streptomyces tenebrarius.Target: AntibacterialTobramycin is an aminoglycoside antibiotic derived from Streptomyces tenebrarius and used to treat various types of bacterial infections, particularly Gram-negative infections. It is especially effective against species of Pseudomonas [1]. Tobramycin works by binding to a site on the bacterial 30S and 50S ribosome, preventing formation of the 70S complex. As a result, mRNA cannot be translated into protein and cell death ensues. Tobramycin is preferred over gentamicin for Pseudomonas aeruginosa pneumonia due to better lung penetration.
