Journal ArticleDOI
Antibacterial activity of quaternary ammonium chitosan containing mono or disaccharide moieties: preparation and characterization
TL;DR: The results showed that the presence of hydrophobic moiety such as the N-benzyl group enhanced the antibacterial activity compared to the hydrophilic moiety against both bacteria.
Journal ArticleDOI
Quaternization of N-aryl chitosan derivatives: synthesis, characterization, and antibacterial activity.
TL;DR: 17 derivatives of chitosan consisting of a variety of N-aryl substituents bearing either electron-donating or electron-withdrawing groups are synthesized and it is found that derivatives with higher ES exhibited reduced antibacterial activity due to low quaternary ammonium moiety content.
Journal ArticleDOI
Physicochemical properties and antioxidant activity of chitosan from the blowfly Chrysomya megacephala larvae.
TL;DR: The blowfly larvae could be a novel alternative source of chitosan and might be used as a natural antioxidant.
Journal ArticleDOI
Insecticidal and fungicidal activity of new synthesized chitosan derivatives.
Entsar I. Rabea,Mohamed E. I. Badawy,Tina Rogge,Christian V. Stevens,Monica Höfte,Walter Steurbaut,Guy Smagghe +6 more
TL;DR: In a radial hyphal growth bioassay with both plant pathogens, all derivatives showed a higher fungicidal action than chitosan, and the effect of different substitutions is discussed in relation to insecticidal and fungicidal activity.
