Clinical Pharmacology Glossary Chemotherapeutic Antimetabolites Antimetabolites: methotrexate, 5 fu, & others overviewhighlights • methotrexate (mtx) inhibits dihydrofolate reductase. methotrexate can lead to interstitial and alveolar infiltrates, as well as pleural effusions. • 5 fluorouracil (5 fu) inhibits. Antimetabolite drugs can be categorised into three primary subgroups: folic acid antagonists. purine analogues. pyrimidine analogues. 1. folic acid antagonists. methotrexate is both a chemotherapeutic agent and a general immunosuppressant for systemic inflammatory diseases such as rheumatoid arthritis and psoriasis.

Abstract. it is almost 50 years since antimetabolites were first found to have clinical antitumour activity, with farber's discovery that aminopterin could cause remission in acute leukaemia. in the following 10 years, methotrexate, 6 mercaptopurine and 5 fluorouracil (5 fu) found their way into clinical practice. The antimetabolites constitute a large group of anticancer drugs that interfere with metabolic processes vital to the physiology and prolifer ation of cancer cells. the major classes of the antimetabolites are the antifols, the purine analogues, and the pyrimidine analogues [1 4]. antimetabolites have been used in cancer treatment since 1948,. Antimetabolites: antimetabolites are a class of drugs that interfere with normal metabolic processes by structurally resembling natural metabolites or substrates, thereby disrupting essential cellular functions. these drugs are primarily used in the treatment of cancer, viral infections, and other conditions where rapid cell division is a key.

Antimetabolite chemotherapy chemotherapy osteosarcoma agents belong to the cell cycle–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). the cell's progression through these phases is punctuated. Purine and pyrimidine antimetabolites have been shown to be highly effective against solid tumors such as colon and breast cancers, as well in certain hematological malignancies. effectiveness has also been shown against primary tumors and against select advanced metastatic cancers. the mechanism of action and toxicity profiles associated with.
