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.
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.
Fluorouracil has been given systemically for anal, breast, colorectal, oesophageal, stomach, pancreatic and skin cancers (especially head and neck cancers). [12] It has also been given topically (on the skin) for actinic keratoses, skin cancers and Bowen's disease [12] (a type of cutaneous squamous-cell carcinoma), and as eye drops for treatment of ocular surface squamous neoplasia. [13]
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 ...
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]
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.
Similarly, the simple-ring structure of cytosine, uracil, and thymine is derived of pyrimidine, so those three bases are called the pyrimidine bases. [6] Each of the base pairs in a typical double-helix DNA comprises a purine and a pyrimidine: either an A paired with a T or a C paired with a G.
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 ...
