Binding of aminoglycoside antibiotics to acidic mucopolysaccharides.
Binding of aminoglycoside antibiotics to acidic mucopolysaccharides has been studied by means of physicochemical methods. Reactivity was affected markedly by the ionic environment , e.g. pH and ionic strength of the medium, the concentrations and the molar ratios of the constituents. The ionic character of binding was further confirmed by gel chromatography. The reduction of metachromasis by an...
متن کاملDNA-Aptamers Binding Aminoglycoside Antibiotics
Aptamers are short, single stranded DNA or RNA oligonucleotides that are able to bind specifically and with high affinity to their non-nucleic acid target molecules. This binding reaction enables their application as biorecognition elements in biosensors and assays. As antibiotic residues pose a problem contributing to the emergence of antibiotic-resistant pathogens and thereby reducing the eff...
متن کاملModulation of RNA function by aminoglycoside antibiotics.
One of the most important families of antibiotics are the aminoglycosides, including drugs such as neomycin B, paromomycin, gentamicin and streptomycin. With the discovery of the catalytic potential of RNA, these antibiotics became very popular due to their RNA-binding capacity. They serve for the analysis of RNA function as well as for the study of RNA as a potential therapeutic target. Improv...
متن کاملSerum protein binding of the aminoglycoside antibiotics.
The binding of four aminoglycoside antibiotics by human serum was investigated under controlled conditions of physiological pH and temperature, by means of an ultrafiltration technique. No serum binding was demonstrable for gentamicin, tobramycin, or kanamycin, whereas streptomycin was 35% bound. Previous conflicting studies are discussed, and some of the pharmacological implications are consid...
متن کاملAminoglycoside antibiotics bind to the influenza A virus RNA promoter.
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.
