Floxuridine Uses
2'-Deoxy-5-fluorouridine (CAS NO.50-91-9) can be used as antineoplastic agents.It is applicable in the treatment of liver cancer, gastrointestinal cancer, breast cancer and head and neck cancer. It may make bone marrow suppression. Local gastrointestinal reactions and skin reactions similar to side effects and fluorouracil. Also it can have the phenomenon which alkaline phosphatase, serum transaminases, serum bilirubin and lactate dehydrogenase increased .
Floxuridine Production
The production methods of 2'-Deoxy-5-fluorouridine (CAS NO.50-91-9) is methyl -2 - deoxy-D-glucoside hydrolyzed by P-Toluoyl chlorid and acetic acid - hydrochloric acid ,make a methoxy substituted by chlorine. Then the product is of condensation with 1 -acetyl-oxygen Mercury -5 - fluorouracil, and the condensation product removed benzoyl- A by hydrolyzed and derived the product.
