Tegafur/uracil (abbreviation: UFT [1]) is a chemotherapy drug combination used in the treatment of cancer, primarily bowel cancer. UFT is an oral formulation combining uracil (a competitive inhibitor of dihydropyrimidine dehydrogenase ), and tegafur (a bioavailable 5-fluorouracil (5-FU) prodrug ) in a 4:1 molar ratio.
Liver (with uracil) [4] Pancreatic; It is often given in combination with drugs that alter its bioavailability and toxicity such as gimeracil, oteracil or uracil. [3] These agents achieve this by inhibiting the enzyme dihydropyrimidine dehydrogenase (uracil/gimeracil) or orotate phosphoribosyltransferase (oteracil). [3]
Tegafur/gimeracil/oteracil, sold under the brand name Teysuno among others is a fixed-dose combination medication used for the treatment of advanced gastric cancer when used in combination with cisplatin, [3] and also for the treatment of head and neck cancer, colorectal cancer, non–small-cell lung, breast, pancreatic, and biliary tract cancers.
Uracil is also involved in the biosynthesis of polysaccharides and the transportation of sugars containing aldehydes. [22] Uracil is important for the detoxification of many carcinogens, for instance those found in tobacco smoke. [23] Uracil is also required to detoxify many drugs such as cannabinoids (THC) [24] and morphine (opioids). [25]
This compound exists in all living organisms and can become part of DNA in both prokaryotic and eukaryotic cells through two mechanisms. The first is the removal of an amino group from cytosine to result in uracil and the second is the non-intentional incorporation of pyrimidine where thymine belongs in the DNA, resulting in dUMP. [3]
Uracil is one of the chemical building blocks for RNA, a molecule carrying directions for building and operating living organisms. Asteroid discovery suggests ingredients for life on Earth came ...
Uramustine or uracil mustard is a chemotherapy drug which belongs to the class of alkylating agents. [1] It is used in lymphatic malignancies such as non-Hodgkin's lymphoma . It works by damaging DNA , primarily in cancer cells that preferentially take up the uracil due to their need to make nucleic acids during their rapid cycles of cell ...
The outer red layer in this diagram is the capsule, which is distinct from the cell envelope. This bacterium is gram-positive, as its cell envelope comprises a single cell membrane (orange) and a thick peptidoglycan-containing cell wall (purple). The bacterial capsule is a large structure common to many bacteria. [1]
