Medical Definition of Antimetabolite

Antimetabolite: A drug that is similar enough to a natural chemical to participate in a normal biochemical reaction in cells but different enough to interfere with the normal division and functions of cells. So named because the drug inhibits a normal metabolic process. Examples of antimetabolites include 6-mercaptopurine (6MP), methotrexate, and hydroxyurea.
