Fluorouracil (5-FU, 5-fluorouracil), sold under the brand name Adrucil among others, is a cytotoxic chemotherapy medication used to treat cancer. [3] By intravenous injection it is used for treatment of colorectal cancer , oesophageal cancer , stomach cancer , pancreatic cancer , breast cancer , and cervical cancer . [ 3 ]
5-Fluoroorotic acid (5FOA) is a fluorinated derivative of the pyrimidine precursor orotic acid. It is used in yeast genetics to select for the absence of the URA3 gene, which encodes the enzyme for the decarboxylation of 5-fluoroorotic acid to 5-fluorouracil , a toxic metabolite. [ 1 ]
The dose schedule given every two weeks is as follows: [5] Day 1–2: Oxaliplatin 100 mg/m 2 IV infusion, given as a 120 minutes IV infusion in 500 mL D5W, concurrent with leucovorin 400 mg/m 2 (or levoleucovorin 200 mg/m 2) IV infusion, followed by 5-FU 400 mg/m 2 IV bolus, followed by 46-hour 5-FU infusion (2400 mg/m 2 for first two cycles, and may be increased to 3000 mg/m 2 if tolerated by ...
Fluorodeoxyuridylate, [1] also known as FdUMP, 5-fluoro-2'-deoxyuridylate, and 5-fluoro-2'-deoxyuridine 5'-monophosphate, is a molecule formed in vivo from 5-fluorouracil and 5-fluorodeoxyuridine. FdUMP acts as a suicide inhibitor of thymidylate synthase (TS). By inhibiting the deoxynucleotide biosynthesis, FdUMP stops the rapidly proliferation ...
5-Fluorouracil (5-FU), the nucleobase of doxifluridine, is currently an FDA-approved antimetabolite. [2] 5-FU is normally administered intravenously to prevent its degradation by dihydropyrimidine dehydrogenase in the gut wall. Doxifluridine is a fluoropyrimidine derivative of 5-FU, thus a second-generation nucleoside prodrug.
Tegafur is a chemotherapeutic prodrug of 5-fluorouracil (5-FU) used in the treatment of cancers. It is a component of the combination drug tegafur/uracil. When metabolised, it becomes 5-FU. [1] It was patented in 1967 and approved for medical use in 1972. [2]
Uracil that was formed extraterrestrially has been detected in the Murchison meteorite, [7] in near-Earth asteroid Ryugu, [8] and possibly on the surface of the moon Titan. [9] It has been synthesized under cold laboratory conditions similar to outer space, from pyrimidine embedded in water ice and exposed to ultraviolet light.
As fluorouracil, carmofur has been known to induce leukoencephalopathy, characterized by progressive damage to white matter in the brain with stroke-like symptoms. [ 8 ] [ 9 ] [ 10 ] A clinical trial for small hepatocellular carcinoma was stopped prematurely because 56% of the treated patients had unacceptable side effects.
