antimetabolites,医学意思
Antimetabolites are a type of medication used in medicine, particularly in the field of oncology. They are substances that interfere with the normal metabolic processes of cells, particularly those involved in the synthesis of DNA and RNA. By disrupting these processes, antimetabolites prevent cancer cells from growing and dividing.
Antimetabolites can be used to treat various types of cancer, including leukemia, breast cancer, and colorectal cancer. They are often administered as part of chemotherapy regimens and can be given orally or intravenously.
Examples of antimetabolites include methotrexate, 5-fluorouracil (5-FU), and cytarabine. Each antimetabolite works by targeting specific metabolic pathways within cells, inhibiting the production of essential components needed for cell growth and division.
While antimetabolites can effectively kill cancer cells, they can also affect normal, healthy cells that have high rates of division, such as those in the bone marrow and gastrointestinal tr
act. This can lead to side effects such as bone marrow suppression, gastrointestinal disturbances, and hair loss.
types是什么意思Overall, antimetabolites play a significant role in cancer treatment by disrupting the metabolism of cancer cells and inhibiting their growth.
