30.12.2016 · Gemcitabine is a chemotherapy drug that is classified as an antimetabolite. It is used to treat multiple cancers, including non-small cell lung cancer (NSCLC), pancreatic cancer, bladder cancer, soft-tissue sarcoma, metastatic breast cancer, and ovarian cancer. Gemcitabine is given to the patient through an IV line, and the dosage and schedule ...

Sep 19, 2021 · How antimetabolites interfere with cancer replication. Folic acid analogs. These disrupt the enzyme called dihydrofolate reductase, which is needed to convert folic acid to the molecule tetrahydrofolate. Pyrimidine analogs. These are molecules that closely resemble the pyrimidines cytosine and ...

What are 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). Antimetabolites are drugs used in cancer chemotherapy.

Some antimetabolites that are commonly used to treat cancer include: 6-mercaptopurine fludarabine 5- fluorouracil gemcitabine cytarabine pemetrexed methotrexate

Antimetabolites are a group of chemotherapy drugs that mimic molecules that cancer cells need to create their DNA. When cancer cells ...

Antimetabolite drugs were among the first effective chemotherapeutic agents discovered. Pyrimidine Compounds. In 1957 scientists introduced 5-flurouracil (5-FU). 5-FU is a pyrimidine base containing a fluoride atom at the 5 carbon position on the ring. Uracil is a naturally occurring pyrimidine base used in nucleic acid synthesis.

Antimetabolite chemotherapy agents belong to the cell-cycle Cycle The type of signal that ends the inspiratory phase delivered by the ventilator Invasive Mechanical Ventilation –specific drugs, which act on a specific phase of the cell cycle Cell cycle The phases of the cell cycle include interphase (G1, S, and G2) and mitosis (prophase, metaphase, anaphase, and telophase).

Antimetabolites replace natural substances as building blocks in DNA molecules, thereby altering the function of enzymes required for cell metabolism and ...

Antimetabolites are group of anticancer agents that exert their cytotoxic effects by interfering with the DNA synthesis. Some of the important drugs from ...

Antimetabolite chemotherapy agents belong to the cell cycle specific drugs, which act on a specific phase of the cell cycle.

One of the common approaches in treatment of cancer is to use drugs that target fast-dividing cells at different phases of the cell cycle.

Antimetabolites can be used in cancer treatment, as they interfere with DNA production and therefore cell division and tumor growth.
