Purinethol Uses

How Does It Work?

Purinethol is similar in structure to purines, which are natural substances that help make up the structure of DNA. Cells incorporate Purinethol into their structure, where the drug interferes with certain reactions that are important for DNA to replicate. Because DNA replication is necessary for cells to divide, Purinethol slows down the growth of cancer cells, and causes the cancer cells to die.
