Applications
Hydroxyurea is a nucleoside diphosphate reductase inhibitor, can prevent nucleotide reduction for DNA, interfere with the purine and pyrimidine bases biosynthesis, selective blocking DNA synthesis, partially inhibit RNA into DNA nucleotides.
Hydroxyurea specific drugs for cycle, sensitive to S phase cells, can induce the hematology ease of chronic myelogenous leukemia, and alkylating agent white Ann elimination, horses, compared to flange secondary leukemia incidence is low.
this product is a derivative of 5-fluorouracil, the role and application of the product is the same as 5-fluorouracil, but it has less toxicity and its chemotherapy index is high. After the activion by the liver in vivo ,it becomes 5-fluorouracil to play a role in cancer. It is effective on Gastric cancer, colon cancer, colorectal cancer, pancreatic cancer and breast cancer, lung cancer. |
