Antifungal properties of Schiff bases of chitosan, N-substituted chitosan and quaternized chitosan.
TL;DR: The results showed that quaternized chitosan had better inhibitory properties than ch itosan, Schiff bases of chitOSan, and N-substituted chITosan.

Relevance of molecular weight of chitosan and its derivatives and their antioxidant activities in vitro
TL;DR: Low molecular weight chitosan had stronger scavenging effect on O(2)(.-) and (-.)OH than high molecular weight ChITosan and sulfated chitOSan derivatives and CTS4 showed more considerable ferrous ion-chelating potency than others.

Novel derivatives of chitosan and their antifungal activities in vitro
TL;DR: Three kinds of Schiff bases of carboxymethyl chitosan (CMCTS) were prepared, and their antifungal activities were assessed according to Jasso de Rodríguez's method.
183
The influence of molecular weight of quaternized chitosan on antifungal activity
TL;DR: Quaternized chitosan derivatives with different molecular weights were synthesized in the laboratory and test their antifungal activities against Botrytis cinerea Pers.

Preparation of high-molecular weight and high-sulfate content chitosans and their potential antioxidant activity in vitro
TL;DR: In this paper, the effect of preparation conditions of sulfated chitosans on their molecular weight and sulfur content, such as different reaction time, acid solvent and temperature, was described.
