Chitin and chitosan, typical marine polysaccharides as well as abundant biomass resources,
are attracting a great deal of attention because of their distinctive biological and …

A novel water-soluble chitosan derivative, O-fumaryl-chitosan (OFCS), was prepared by
using the selective partial acylation of chitosan and fumaric acid in the presence of H2SO4 …

Chitosan derivatives were prepared by dialkylaminoalkylation and reductive amination
followed by quaternization. In this study, the cytotoxic activity of the chitosan derivatives was …

Chitosan (CS) derivatives with improved water solubility, antibacterial activity and adequate
biocompatibility are attracting increasingly interest in medical application. Herein, we have …

Three novel quaternary chitosan derivatives were successfully synthesized by reaction of
chloracetyl chitosan (CACS) with pyridine (PACS), 4-(5-chloro-2-hydroxybenzylideneamino) …

Chitosan and its oligosaccharides, which are known to possess multiple functional
properties, have attracted considerable interest due to their biological activities and potential …

A novel water-soluble chitosan oligosaccharide (COS) derivative, chitosan
oligosaccharide/kojic acid grafts assigned as COS/KA, was prepared by using the selective …

The novel chitosan oligosaccharide derivatives modified with cinnamyl onto the NH 2
position were synthesized through a one-step reaction and their in vitro antibacterial …

Biodegradable chitin is the second-most abundant natural polysaccharide, widely existing in
the exoskeletons of crabs, shrimps, insects, and the cell walls of fungi. Chitosan and …

Chitosan has received much attention for its role in designing and developing novel
derivatives as well as its applications across a broad spectrum of biological and …
