Subacute Toxicity of Chitosan Oligosaccharide in Sprague-Dawley Rats

Arzneimittelforschung, 2011
A subacute oral toxicity study of chitosan oligosaccharide was performed in Sprague-Dawley rats of both sexes. Each 36 male and female rats were administered by gavage with 500, 1,000 and 2,000 mg/kg/day for 4 weeks (7 days/week), respectively.

Microencapsulation of norfloxacin in chitosan/chitosan oligosaccharides and its application in shrimp culture

International Journal of Biological Macromolecules, 2016
Norfloxacin chitosan/chitosan oligosaccharide microcapsules (NCCM) were prepared by emulsion-chemical crosslinking method. The characteristics of obtained microcapsules were evaluated by scanning electron microscopy, Fourier transform infrared spectroscopy and release experiments.

Geraniol grafted chitosan oligosaccharide as a potential antibacterial agent

Carbohydrate Polymers, 2017
The novel derivatives of geraniol grafted chitosan oligosaccharide were synthesized via substitution and deprotection reaction, respectively. The products were identified by Fourier transform infrared (FT-IR), 1H nuclear magnetic resonance (NMR), X-ray diffraction analysis (XRD), Thermogravimetric analysis (TGA) and UV-vis absorption spectroscopy.

Sustained release of ATP encapsulated in chitosan oligosaccharide nanoparticles

International Journal of Pharmaceutics, 2010
The chemical cross-linked chitosan oligosaccharide (CSO) nanoparticles containing ATP/CSO ionic complex nano-components were prepared using combination techniques of W/O miniemulsion, chemical cross-linking and ionic complexation. The resulted nanoparticles had about 110 nm diameter and 20 mV surface zeta potential.

Modification of Chitosan/Chitin and Its Oligosaccharides

2019
In view of rapidly growing interest in the amino polysaccharide chitosan/chitin and its oligosaccharides as functional biopolymer, a recent progress of basic and application studies in chitosan/chitin oligosaccharides chemistry is reviewed as well as some basic aspects of this specialty biomass resource.

Valorization of shrimp processing waste-derived chitosan into anti-inflammatory chitosan-oligosaccharides (CHOS)

Carbohydrate Polymers
Bioconversion of chitosan into soluble anti-inflammatory chitosan oligosaccharides (CHOS) using a Bacillus chitosanase, BsCsn46A, was investigated, including food-grade approaches. After 48 h of enzymatic reaction, most of the final products were dimers and trimers. None of the CHOS products showed toxicity to human fibroblasts.

Chitosan and its oligosaccharide derivatives (chito‐oligosaccharides) as feed supplements in poultry and swine nutrition

Journal of Animal Physiology and Animal Nutrition, 2014
SummaryChitosan is a non‐toxic polyglucosamine, widespread in nature, which is deacetylated to varying degrees form of chitin, a component of exoskeleton of shrimps, crabs and insects. Because chitosan contains reactive functional groups, that is, amino acids and hydroxyl groups, it is characterised by antimicrobial, anti‐inflammatory, anti‐oxidative ...

Methotrexate-Loaded Chitosan Oligosaccharide-ES2 for Targeted Cancer Therapy

ACS Applied Materials & Interfaces
Cancer presents a significant health threat, necessitating the development of more precise, efficient, and less damaging treatment approaches. To address this challenge, we employed the 1-ethyl-(3-dimethyl aminopropyl) carbodiimide/N-hydroxy succinimide (EDC/NHS) catalytic system and utilized quaternized chitosan oligosaccharide (HTCOSC) as a drug ...
