Efficacy and function of adenosine arabinoside
Uridine powder is a commonly used antiviral drug, especially for common viral infections in children. In fact, it is a purine nucleoside. Doctors often use adenosine monophosphate solution, After use, it is rapidly deaminated into bioactive arabinose hypoxanthine. It can easily pass through the blood-brain barrier. The concentration in cerebrospinal fluid reaches 1 / 3 of the blood concentration. Clinically, it is used for herpes simplex encephalitis, herpes zoster virus infection, and varicella-zoster virus infection. In addition, it also has a certain curative effect on some common viruses, such as the Coxsackie virus, ECHO virus, and enterovirus.
How to use this product to make high-quality cytarabine includes?
The latest scientific and technological method for preparing cytarabine is to react Uridine with acetic anhydride or acetyl chloride or acetyl bromide in pyridine to obtain ethyl arabinoside. Ethyl arabinoside reacts with triazole platform under the action of phosphorus oxychloride and Sui organic solvent to obtain triazole uridine, and triazole uridine ammonolysis to obtain cytarabine. The method overcomes the shortcomings of the prior art, the selected solvent is cheap, the dosage is small, and the industrial preparation yield is high. The crude cytarabine was separated and purified by strong acid cation exchange resin, and the obtained cytarabine product met the requirements of European and American Pharmacopoeia.
Can arabinose uridine treat tumors?
Cytarabine is the first marine anticancer agent. It is the first chemotherapeutic drug to change the structure of nucleoside and play an anti-tumor role. Although there is no relevant research on the treatment of tumors with Arabinosuridine. However, this product can synthesize cytarabine and become an indispensable raw material for the manufacture of antitumor drugs slowly.
