Progress of antibacterial activity and antibacterial mechanism of isoquinoline alkaloids
China Journal of Chinese Materia Medica, 2016This paper reviewed the antibacterial activity and structure-activity relationship of isoquinoline alkaloids, such as protoberberine, protopine, benzophenanthridine, aporphine, double benzyl isoquinoline, etc. The antibacterial mechanism of alkaloids were illustrated from cell wall and membrane damage, membrane permeability changes, related enzymes and

Antibacterial Carbon Dots: Mechanisms, Design, and Applications
Advanced Healthcare Materials, 2023AbstractThe increase in antibiotic resistance promotes the situation of developing new antibiotics at the forefront, while the development of non‐antibiotic pharmaceuticals is equally significant. In the post‐antibiotic era, nanomaterials with high antibacterial efficiency and no drug resistance make them attractive candidates for antibacterial ...

[Antibacterial mechanism of chitosan].
Wei sheng wu xue bao = Acta microbiologica Sinica, 2009In this study, we found that many metal ions could affect the antibacterial activity of chitosan, such as K+, Na+, Mg2+ and Ca2+. High concentration (about 0.5%) of metal ions could make chitosan completely lose its antibacterial activity, except for the effect of Na+ on the antibacterial activity against Staphylococcus aureus.

Mechanism of antibacterial activity of copper nanoparticles
Nanotechnology, 2014In a previous communication, we reported a new method of synthesis of stable metallic copper nanoparticles (Cu-NPs), which had high potency for bacterial cell filamentation and cell killing. The present study deals with the mechanism of filament formation and antibacterial roles of Cu-NPs in E. coli cells.

Mechanisms of antibacterial immunity of mucous membranes
Folia Microbiologica, 1984A survey based on both literary data and the authors own results, concerning the mechanisms of sIgA-mediated antibacterial immunity, is presented. Secretory IgA is characterized as a specific component of the immune system of mucous membranes, which can recognize harmful bacterial and distinguish them from indigenous microflora physiologically ...

Mechanism of the antibacterial action of spermine
Archives of Biochemistry and Biophysics, 1959Abstract 1. 1. Spermine was adsorbed by various bacterial cells, following an adsorption isotherm. No correlation was observed between the quantity of spermine adsorbed by the bacteria and their sensitivity to the drug. The adsorption of spermine decreased in the presence of high concentrations of hydrogen ions or other cations. 2. 2. Various

Antibacterial mechanisms of graphene-based composite nanomaterials
Nanoscale, 2017Pathogenic bacteria are gaining resistance to conventional antibiotics at an alarming rate due to overuse and rapid transfer of resistance genes between bacterial populations. As bacterial resistance to antibiotics causes millions of fatalities worldwide, it is of urgent importance to develop a new class of antibiotic materials with both broad-spectrum

Lasso-inspired peptides with distinct antibacterial mechanisms
Amino Acids, 2014Microcin J25 (MccJ25) is an antibacterial peptide with a peculiar molecular structure consisting of 21 amino acids and a unique lasso topology that makes it highly stable. We synthesized various MccJ25-derived peptides that retained some of the inhibitory activity of the native molecule against Salmonella enterica and Escherichia coli.

Antibacterial Effects of Chitosan Powder: Mechanisms of Action
Environmental Technology, 2007Chitosan, the deacetylated derivative of chitin, is a natural D-glucosamine polymer that can be extracted from the shells of seafood such as prawns crabs and lobsters. It can be used as a flocculent, plant disease resistant promoter, anti-cancer agent, wound healing promotion agent and antimicrobial agent.
