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.
