The Antioxidant Activities of C3, 6-Dibenzoylated Phenyl-Thiosemicarbazone-Chitosans

Chemical modification of CS and its derivatives can enhance their properties and consequently expands their potential applications. And because of this, CS and its derivatives have been used in a number of different fields nowadays. They are an important class of N, S donor ligands which attract considerable interest because of their chemistry and biological activities, such as antitumor, antibacterial, antiviral, antiamoebic and antimalarial activities [3], so more and more people are researching their bioactivities. At present, there are all kinds of thiosemicarbazone derivatives, and their bioactivities were determined [4].
