Immunopotentiating Effect of N-Acetyl-Chito-Oligosaccharides
1986In our previous papers on this subject (1, 2), we revealed that chit in and chitosan were able to display growth-inhibitory effects against tumor cells or pathogenic microbes inoculated in the peritoneal cavity of mice. The action mechanism of both polysaccharides was assumed to involve the active tion of phagocytic cells attracted to the peritoneal ...

Phenylethanoid glycosides, the main active ingredients in Fructus Forsythiae extract possesses strong antibacterial, antioxidant and antiviral effects, and their contents were higher largely than that of other ingredients such as lignans and flavones, but their absolute bioavailability orally was significantly low, which influenced clinical efficacies ...

A chitosanase from Paecilomyces lilacinus with binding affinity for specific chito‐oligosaccharides
Biotechnology and Applied Biochemistry, 2005A purple‐spore, rhizosphere‐inhabiting nematophagous fungus, further identified as Paecilomyces lilacinus, was found to grow on chitosanase‐detecting plate. An induced endochitosanase having a molecular mass of 23 kDa was purified from the culture medium by a single cation‐exchange column‐chromatography step.

N-furoyl chitosan (NF-CS) and N-furoyl chitosan oligosaccharide (NF-COS) were prepared via acylation of chitosan and chitosan oligosaccharide. Their chemical structures and physical properties were characterized by Fourier transform infrared spectroscopy, (1)H NMR, X-ray diffraction, and elemental analysis.

We describe the synthesis of N-trifluoroacetyl chito-oligosaccharides and their use as ligands to probe the binding sites of wheat-germ agglutinin, a lectin specific for N-acetylglucosamine. The binding is monitored using intrinsic protein fluorescence, which is due to tryptophan side-chains.

[The inactivating effect of chito-oligosaccharides on TMV particles in vitro].
Bing du xue bao = Chinese journal of virology, 2008To confirm the inactivating effect of chito-oligosaccharides on Tobacco mosaic virus (TMV) par ticles in vitro, the difference of TMV pathogenicity was evaluated according to the decrease of local lesion numbers after inoculating with TMV mixed with chito-oligosaccharides (DP3-10) in Nicotiana glutinosa, and the virion structural change was studied by ...
