Product Description

High Quality 99%Min CAS32986-56-4 Tobramycin base

 

Molecular Formula: C18H37N5O9
Molecular Weight: 467.52 g/mol
CAS: 32986-56-4
Appearance: white powder
Tobramycin is an aminoglycoside antibiotic derived from Streptomyces tenebrarius with bacteriostatic activity. Following active transport into the cell, tobramycin binds irreversibly to a specific aminoglycoside receptor on the bacterial 30S ribosomal subunit and interferes with the initiation complex between messenger RNA and the 30S subunit, thereby inhibiting initiation of protein synthesis, consequently leading to bacterial cell death. In addition, tobramycin induces misreading of the mRNA template causing incorrect amino acids to be incorporated into the growing polypeptide chain, consequently interfering with protein elongation.
