Abstract:
At present, the polysaccharide antitumor research is focused on how to further improve the antitumor activity of polysaccharides. The structural modification of polysaccharides can enhance their antitumor activity to a certain extent. The antitumor mechanisms of polysaccharide derivatives mainly contain the inducing apoptosis of tumor cells, effecting on the cycle of tumor cells, enhancing the antioxidant activity of organism, activating the body's immune response and inhibiting the tumor angiogenesis. Herein, the common methods of polysaccharide modification, such as sulfation, carboxymethylation, phosphorylation and acetylation, were summarized. At the same time, the effects of chemical modification of polysaccharides on their antitumor mechanisms and activity were analyzed and discussed.
