Antibiotics, Aminoglycoside (C0003233)

Definition (NCI) Any antibiotic containing amino-modified sugars originally isolated from various Streptomyces and Micromonospora species. Aminoglycoside antibiotics bind to the 16S RNA of the bacterial 30S ribosomal subunit, inhibiting translation and protein synthesis. Aminoglycoside use is associated with ototoxicity, neurotxicity and nephrotoxicity.
Definition (NCI_NCI-GLOSS) A family of antibiotics that works against many types of bacteria and includes streptomycin, gentamicin, and neomycin. Aminoglycosides are used to treat bacterial infections.
Definition (CSP) any of a group of antibiotics derived from various species of Streptomyces or produced synthetically; they inhibit protein synthesis by binding with the 30S ribosomal subunit.

Definition (CHV) a kind of antibiotics
Definition (MSH) A complex antibiotic substance produced by MICROMONOSPORA purpurea, with three components: gentamicin C1, C2 , and C1A sulfates.
Definition (NCI) The sulfate salt form of gentamycin, a broad-spectrum aminoglycoside antibiotic complex produced by the fermentation of Micromonospora purpurea or M. echinospora, with antibacterial activity. Gentamicin is a thermostable complex containing the gentamicins C1, C1a, C2, C2a and C2b.
Definition (NCI) A broad-spectrum aminoglycoside antibiotic produced by fermentation of Micromonospora purpurea or M. echinospora. Gentamicin is an antibiotic complex consisting of four major (C1, C1a, C2, and C2a) and several minor components. This agent irreversibly binds to the bacterial 30S ribosomal subunit. Specifically, this antibiotic is lodged between 16S rRNA and S12 protein within the 30S subunit. This leads to interference with translational initiation complex, misreading of mRNA, thereby hampering protein synthesis and resulting in bactericidal effect. Aminoglycosides are mostly ineffective against anaerobic bacteria, fungi and viruses.
Definition (CSP) complex of three different closely related aminoglycoside sulfates, obtained from Micromonospora purpurea and related species; broad-spectrum antibiotics; may cause ear and kidney damage; they act to inhibit protein synthesis.
