Antimetabolites

Antimetabolites are substances that interfere with the normal metabolic processes in cells, particularly in rapidly dividing ones, like cancer cells. They mimic the building blocks of DNA or RNA, which are essential for cell growth and division. When these substances are incorporated into the cell’s processes, they disrupt the formation of DNA or RNA, ultimately inhibiting cell reproduction. Because of their ability to target fast-growing cells, antimetabolites are commonly used in chemotherapy to treat various cancers, helping to slow down or stop tumor growth. However, they can also affect healthy cells, leading to side effects.
