Synthesis method

1. Glucose is one of the most abundant compounds in nature and is a product of photosynthesis. It exists in free form in plant juices, especially in fruits, honey, plasma, and lymph. The glucose content in normal human blood is 0.08%-0.1%, and a larger amount of it exists in the form of combined sucrose, starch, glycogen, cellulose and glycosides. Initially glucose was separated and crystallized from grape juice, hence its name. Industrially produced glucose is produced by hydrolysis of starch. In the past, dilute hydrochloric acid was used to hydrolyze starch. Now, dilute hydrochloric acid is almost completely replaced by enzymatic hydrolysis.

2.Starch can be hydrolyzed to obtain glucose.

Purpose

1. Can be used as nutritional sweeteners, water retaining agents, texture improvers, molding and processing aids.

2. Can be used as reducing agent, biological culture medium and biochemical reagents.

Properties and stability

Rapid intravenous injection can quickly degrade into 5-fluorouracil, with the same effects and side effects as 5-fluorouracil. Continuous arterial infusion can be directly converted into 5-fluorodeoxyurea, thereby inhibiting DNA synthesis. Effective results can be obtained with a smaller dose, which is three times higher than rapid intravenous infusion.

Storage method

This product should be sealed with argon gas and stored at 0~4?.

Synthesis method

Methyl-2-deoxy-D-ribofuranoside is p-toluoylated and hydrolyzed with acetic acid-hydrochloric acid to replace the methoxy group at position 1 with chlorine, and then combined with 1 – The condensation of mercury acetoxy-5-fluorouracil is obtained by hydrolyzing the product to remove the p-toluyl group.

Purpose

1. Biochemical research. Inhibitor of DNA synthesis. Medical antiviral agent, antitumor agent.

2.Anti-tumor drugs. It is suitable for the treatment of liver cancer, gastrointestinal cancer, breast cancer and head and neck cancer.
