Aminoglycosides bind to the influenza A virus promoter (vRNA) at submicromolar concentration. The complex structure between the vRNA and neomycin illustrates that binding of neomycin causes a conformational change which would affect further transcription processes. Thus, aminoglycosides represent lead compounds for the discovery of antiviral therapeutics against influenza A virus.

Cellulose phosphate powder can be added to serum to selectively bind aminoglycosides by ionic interaction without binding or inactivation of the penicillins, the cephalosporins, clindamycin, vancomycin, chloramphenicol, or trimethoprim. This simple, rapid technique permits the measurement of non-aminoglycoside antibiotics in the presence of aminoglycosides.

A spontaneous kanamycin-resistant Escherichia coli mutant, showing cross resistance to five other aminoglycosides and absence of the OppA protein was isolated. [H]dihydrostreptomycin uptake is reduced in this mutant, implying that the oligopeptide transport system is involved in accumulation of aminoglycosides, although apparently not related with aminoglycoside permeability alteration due to b...

Several lines of evidence indicate that the first steps in the pathogenesis of anlinoglycoside nephrotoxicity involve the accumulation of the antibiotic in the proximal tubule where it interacts with the plasma membrane of epithelial cells' 2) . In brush border membranes, acidic phospholipids and most particularly phosphoinositides, phosphatidylinositol (PI), phosphatidylinositol-4phosphate (PI...

Aminoglycosides are chemically diverse, broad-spectrum antibiotics that target functional centers within the bacterial ribosome to impact all four principle stages (initiation, elongation, termination, and recycling) of the translation mechanism. The propensity of aminoglycosides to induce miscoding errors that suppress the termination of protein synthesis supports their potential as therapeuti...

Severe sepsis and septic shock are major problems as the result of high rates morbidity and mortality in intensive care units (ICUs). In the presence of septic shock, each hour of delay in the administration of effective antibiotics is associated with a measurable increase in mortality. Aminoglycosides are effective broad-spectrum antibiotics that are commonly used in ICUs for the treatment of ...

Within recent years, it has been established that extracellular DNA is a key constituent of the matrix of microbial biofilms. In addition, it has recently been demonstrated that DNA binds positively charged antimicrobials such as aminoglycosides and antimicrobial peptides. In the present study, we provide evidence that extracellular DNA shields against aminoglycosides in Pseudomonas aeruginosa ...
