In order to improve the antioxidant and antifungal activity of chitosan, eight chitosan
derivatives containing Schiff bases and quaternary ammonium salts were synthesized via an …

In this work, chitosan derivatives modified with Schiff base bearing benzenoid/heterocyclic
moieties were successfully prepared via amidation reaction. Specific structural …

In the present work, quaternary chitosans as water‐soluble compounds were prepared
based on three‐step process. Schiff bases were firstly synthesized by the reaction between …

Three kinds of Schiff bases of carboxymethyl chitosan (CMCTS) were prepared, and their
antifungal activities were assessed according to Jasso de Rodríguez's method. The results …

In this paper, several novel chitosan derivatives bearing benzenoid/heterocyclic moieties
were synthesized via introducing aminobenzene and heterocyclic compounds onto …

In this study, to investigate the influence of glyoxylate bearing Schiff base on bioactivity to
chitosan quaternary ammonium salts, different chitosan derivatives were synthesized by ion …
