Quaternized Chitosan as an Antimicrobial Agent: Antimicrobial Activity, Mechanism of Action and Biomedical Applications in Orthopedics
Chitosan (CS) is a linear polysaccharide with good biodegradability, biocompatibility and antimicrobial activity, which makes it potentially useful for biomedical applications, including an antimicrobial agent either alone or blended with other polymers. However, the poor solubility of CS in most solvents at neutral or high pH substantially limits its use. Quaternary ammonium CS, which was prep...
متن کاملNovel guanidinium and phosphonium polysulfones: synthesis and antimicrobial activity
The possibility of obtaining of new polymeric salts on the basis of guanidinium and phosphonium polysulfones was investigated. Guanidinium and phosphonium polysulfones were synthesized by free radical copolymerization technique. Polysulfonylpyrrolidinium and polysulfonylpyrrolidinylphosphonium hydroxides were obtained by ion chromatography. Chemical modification of hydroxides results in new opt...
متن کاملQuaternized chitosans bind onto preexisting biofilms and eradicate pre-attached microorganisms.
Quaternized chitosans, N,N,N-trimethylchitosans (TMC) with different degree of quaternization were synthesized by reacting methyl iodide with chitosan. The reaction was confirmed by FT-IR and 1H-NMR characterization. Antimicrobial assay showed that the prepared TMC had potent biocidal effects against planktonic Gram-positive bacteria Staphylococcus epidermidis, Gram-negative bacteria Escherichi...
متن کاملAntimicrobial Activity of Chitosan Derivatives Containing N-Quaternized Moieties in Its Backbone: A Review
Chitosan, which is derived from a deacetylation reaction of chitin, has attractive antimicrobial activity. However, chitosan applications as a biocide are only effective in acidic medium due to its low solubility in neutral and basic conditions. Also, the positive charges carried by the protonated amine groups of chitosan (in acidic conditions) that are the driving force for its solubilization ...
متن کاملEffect of glycounits on the antimicrobial properties and toxicity behavior of polymers based on quaternized DMAEMA.
Polymers with quaternary ammonium groups such as quaternized poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMAQ) have been used as antimicrobial agents because of their demonstrated good antimicrobial activities against a huge number and types of microbes, although their cytotoxicity is also well-known. In this work block copolymers based on PDMAEMAQ were synthesized containing hydrophobic seg...
