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 ]
c 6 h 5 cho + r 2 nsf 3 → c 6 h 5 chf 2 + "r 2 nsof" Apart from DAST, a wide variety of similar reagents exist, including, but not limited to, 2-pyridinesulfonyl fluoride (PyFluor) and N -tosyl-4-chlorobenzenesulfonimidoyl fluoride (SulfoxFluor). [ 21 ]
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 ...
Adjuvant treatment in patients with stage III colon cancer is recommended [2] for 12 cycles, every two weeks. The recommended dose schedule is as follows: Day 1: Oxaliplatin 85 mg/m 2 intravenous (IV) infusion in 250-500 mL D5W and leucovorin 200 mg/m 2 IV infusion in D5W administered concurrently over 120 minutes in separate bags using a Y-line, followed by fluorouracil (5-FU) 400 mg/m 2 IV ...
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 optimization of the objective function is usually performed using pairwise Jacobi rotations. [5] However, this approach is prone to saddle point convergence (if it even converges), and thus other approaches have also been developed, from simple conjugate gradient methods with exact line searches, [6] to Newton-Raphson [7] and trust-region ...
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]
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.
