N-substituted chitosan derivatives were synthesized through condensation with a number of selected aryl and heteroaryl aldehydes. The synthesis of the amino-derivatives has been carried out by reductive amination with sodium borohydride as reducing agent. Their structures were characterized by (FT-IR, 1HNMR, and XRD). The antimicrobial activity of Chitosan Schiff’s base (CSB) derivatives were investigated against four types of bacteria and two crop-threatening pathogenic fungi, and the results indicated that the antibacterial and antifungal activities of the investigated derivatives are very promising. Additionally, different concentrations of the triazolo-Schiff’s base derivative 3c were used for cytotoxicity screening against Human Breast Adenocarcinoma Cells (MCF-7), Human Colon Carcinoma Cells (HCT-116), and Human Hepatocellular Liver Carcinoma Cells (HepG-2), and the obtained data revealed that the examined compounds have an excellent cell growth inhibitory effects on the cell lines as compared to standard.
