How are antimetabolites used in cancer treatment?
Antimetabolites can be used in cancer treatment, as they interfere with DNA production and therefore cell division and tumor growth.
What are antimetabolite antibiotics?
Antitumor antibiotics are a class of antimetabolite drugs that are cell cycle nonspecific. They act by binding with DNA molecules and preventing RNA (ribonucleic acid) synthesis, a key step in the creation of proteins, which are necessary for cancer cell survival.
Do antimetabolites work for everyone?
But antimetabolites don’t work for everyone, and it can be hard for doctors to predict whose tumors will respond to these drugs. Even when antimetabolites first work well, tumors often become resistant to these drugs, which means they eventually don’t work anymore.

Why are antimetabolites used in cancer?
Antimetabolites can be used in cancer treatment, as they interfere with DNA production and therefore cell division and tumor growth. Because cancer cells spend more time dividing than other cells, inhibiting cell division harms tumor cells more than other cells.

What are so called antimetabolites?
Antimetabolites are drugs that interfere with one or more enzymes or their reactions that are necessary for DNA synthesis. They affect DNA synthesis by acting as a substitute to the actual metabolites that would be used in the normal metabolism (for example antifolates interfere with the use of folic acid).

What drugs mimic purine?
Medications that mimic purine include azathioprine and cladribine, while medications that mimic pyrimidine include cytarabine and 5-fluorouracil. Finally, there's folic acid analogues like methotrexate. Alright, let’s start with azathioprine which is the prodrug of 6-mercaptopurine, or 6-MP.
What is the prodrug for 6-mercaptopurine?
Alright, let’s start with azathioprine which is the prodrug of 6-mercaptopurine, or 6-MP. Azathioprine is converted to 6-MP by the enzyme thiopurine S-methyltransferase and some 6-MP is converted to 6-thioguanine, or 6-TG.

This and bone marrow suppression are common to all the antimetabolites used for cancer treatment. The decrease in white blood cells leads to immunosuppression, increased risk for infections and exacerbation of chronic infections such as hepatitis B infection and herpes zoster virus infection.
What is an anti-metabolite?
In this chapter, we will talk about anti-metabolites as anti-cancer agents, exemplified by Methotrexate, an anti-folate, and 5-FU as well as Capecitabine as pyrimidine analogues. “Anti-metabolite drugs work by inhibiting essential biosynthetic processes or by incorporating into macromolecules such as DNA and RNA, and inhibiting their normal function.”
Is Capecitabine a prodrug?
Capecitabine is an orally administered prodrug of 5-FU, in contrast to 5-FU, which his administered via IV. Capecitabine is converted by the liver enzyme carboxyl esterase to 5-DFCR (5-deoxy-5-fluorocytidine) and then to 5-DFUR (5-deoxy-5-fluorouridine) by cytidine deaminase, an enzyme expressed in both the liver and in the tumour. 5-DFUR is then converted intracellularly to the antimetabolite 5-FU by thymidine phosphorylase. Tumour specificity is being achieved due to the high level of expression of this enzyme in malignant relative to normal tissue.
