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 ]
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 ...
The method is mainly used to perfluorinate, i.e. replace all C–H bonds by C–F bonds. The hydrocarbon is dissolved or suspended in liquid HF, and the mixture is electrolyzed at 5–6 V using Ni anodes. [15] The method was first demonstrated with the preparation of perfluoropyridine (C 5 F 5 N) from pyridine (C 5 H 5 N).
In this case there are 16 C−C sigma bonds and 10 C−H bonds. This rule fails in the case of molecules which, when drawn flat on paper, have a different number of rings than the molecule actually has - for example, Buckminsterfullerene , C 60 , which has 32 rings, 60 atoms, and 90 sigma bonds, one for each pair of bonded atoms; however, 60 ...
Hyperconjugation affects several properties. [6] [10]Bond length: Hyperconjugation is suggested as a key factor in shortening of sigma bonds (σ bonds). For example, the single C–C bonds in 1,3-butadiene and propyne are approximately 1.46 Å in length, much less than the value of around 1.54 Å found in saturated hydrocarbons.
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 ...
Floxuridine is rapidly catabolized to 5-fluorouracil, which is the active form of the drug. The primary effect is interference with DNA synthesis and to a lesser extent, inhibition of RNA formation through the drug's incorporation into RNA , thus leading to the production of fraudulent RNA.
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]
