Pectin-5-efudix colon cancer double-target ahead body medicament and preparation method

The invention relates to a pectin-5-fluorouracil colon cancer two-targeting prodrug and the preparation method thereof, and mainly synthesizes a two-targeting prodrug for colon cancer by utilizing an anti-cancer drug, 5-fluorouracil (5-FU), and pectin. The two-targeting prodrug for colon cancer is used for treating colon cancer and is characterized in that the 6-digit carboxyl is utilized to be combined with 5-FU directly or through different bridging groups to synthesize a series of two-targeting prodrugs for colon cancer. The prodrug first targets 5-FU to the colon by utilizing pectin to realize colon positioned release, and then 5-FU-galactose is identified through high expression of colon cancer galactin-3, and then 5-Fu is targeted to the colon cancer cells to realize two-targeting of colon cancer to treat colon cancer. The prodrug improves the selectivity of 5-FU greatly, enhances the curative effect and reduces adverse reactions. In addition, the hydrolysis fragments of pectin play a role in resisting tumor metastasis and can have a synergic action with 5-FU. The pectin-5-fluorouracil two-targeting prodrug for colon cancer focuses on the drug design ideas of drug delivery, targeting and coordination; therefore, the prodrug achieves the goal of high selectivity, high efficiency and low toxicity.
