Embodiment 1
[0023] An anti-tumor composition, characterized in that it includes the following components in parts by weight: 20 parts of indole-2,6-dicarboxylic acid / 2,5-furandimethanol polycondensate, selenomethionine modified overspend 10 parts of ethylene glycol chitosan.
[0024] The preparation method of the indole-2,6-dicarboxylic acid / 2,5-furandimethanol polycondensate comprises the following steps: indole-2,6-dicarboxylic acid, 2,5-furandimethanol, Cobalt acetate is added to the polymerization reactor, and the esterification reaction is carried out at a pressure of 0.3MPa and a temperature of 250°C. The esterification reaction is completed when the theoretical water output reaches more than 98%, and then polycondensation is carried out at a vacuum degree of 150Pa and a temperature of 260°C. React for 6 hours, then continue to carry out polycondensation reaction under the condition of vacuum degree of 20Pa and temperature of 270°C for 6 hours, after discharging, cooling, washing, p...
