海因改性N-季铵化壳聚糖衍生物的合成及其抗菌性能
Synthesis and antibacterial research of hydantoin modified quaternary ammonium chitosan
摘要
Abstract
Under acidic condition,N-(2-hydroxy)propyl-3-trimethyl ammonium chloride chitosan (HTCC) was synthesized by reaction of chitosan and glycidy quaternized salts. Then 3-glycidy-5,5-dimethyl hydantoin (made in our lab) was used to synthesize O-hydroxy-propyl (5,5-dimethyl hydantoin)-N-(2-hydroxy)propyl-3-trimethyl ammonium chloride chitosan (GH-HTCC). The products were confirmed by FTIR,1H NMR,UV-VIS,EA. The results of antibacterial tests indicated antibacterial activity of these products with better antimicrobial activity against S. aureus than against E. coil. Antibacterial activity of GH-HTCC was stronger than HTCC and increased as the degree of substitution increased. A lower concentration of EDTA improved antibacterial activity of HTCC and GH-HTCC,but a higher concentration of EDTA inhibited antibacterial activity.关键词
