General description

Chemical structure: aminoglycoside

Biochem/physiol Actions

Mode of action: This product acts by binding to the 30S and 50S subunits, causing miscoding and inhibiting initiation and elongation during protein synthesis. Neomycin also blocks voltage-sensitive Ca2+ channels without affecting the Na+/Ca2+ antiporter in neurons.

Antimicrobial spectrum: Neomycin acts against both gram-positive and gram-negative bacteria.

Use of neomycin eardrops in nonintact tympanic membranes (NITMs) due to tympanic membrane (TM) perforation or tympanostomy tubes (TTs) is controversial because of the potential for ototoxicity. We sought to compare the risk of sensorineural hearing loss (SNHL) in patients

Microemulsions are thermodynamically stable isotropic systems comprising of oil, surfactant and water. Cinnamon oil (Cinnamomum zeylanicum) microemulsion was formulated using non-ionic surfactant Tween 20 and water. With oil to surfactant (v/v) ratio of 1:4, cinnamon oil microemulsion (CMF4) was formulated

Previously, we showed that aminoglycoside phosphotransferases catalyze the formation of a specific inhibitor of the SWI2/SNF2 proteins. Aminoglycoside phosphotransferases, for example neomycin-resistant genes, are used extensively as selection markers in mammalian transfections as well as in transgenic studies. However, introduction
