Neomycin Sulfate is the sulfate salt form of neomycin, a broad spectrum aminoglycoside antibiotic derived from Streptomyces fradiae with antibacterial activity. Neomycin is an antibiotic complex consisting of 3 components: the two isomeric components B and C are the active components, and neomycin A is the minor component. Neomycin irreversibly binds to the 16S rRNA and S12 protein of the bacterial 30S ribosomal subunit. As a result, this agent interferes with the assembly of initiation complex between mRNA and the bacterial ribosome, thereby inhibiting the initiation of protein synthesis. In addition, neomycin induces misreading of the mRNA template and causes translational frameshift, thereby results in premature termination. This eventually leads to bacterial cell death.

Neomycin sulphate Usage And Synthesis

Chemical Properties NEOMYCIN SULFATE is  white or yellowish-white powder, hygroscopic.

NEOMYCIN SULFATE is an aminoglycoside antibiotic found in many topical medications. NEOMYCIN SULFATE has been used as a preventive measure for hepatic encephalopathy and hypercholesterolemia.
NEOMYCIN SULFATE is an aminoglycoside antibiotic produced by S. fradiae that inhibits protein translation by binding to the small subunit of prokaryotic ribosomes. It blocks voltage-sensitive Ca2+ channels and is a potent inhibitor of skeletal muscle sarcoplasmic reticulum Ca2+ release. NEOMYCIN SULFATE has been shown to inhibit inositol phospholipid turnover, phospholipase C, and phosphatidylcholine-phospholipase D activity (IC50 = 65 μM). It is highly effective against Gram-positive and Gram-negative bacteria and is commonly used for the prevention of bacterial contamination of cell cultures.
Neomycin sulfate is an antibiotic (can be used effectively against most bacteria that cause skin, eye and outer ear infections); broad-spectrum antibiotic in topical creams, powders, ointments, eye and ear drops; systemic antibiotic and growth promotor in veterinary use.
