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. [1] It was patented in 1967 and approved for medical use in 1972. [2]
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 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.
Scientists said on Tuesday they detected uracil and niacin in rocks obtained by the Japanese Space Agency's Hayabusa2 spacecraft from two sites on Ryugu in 2019.
Uracil (present in RNA only) 5-carbon sugar which is called deoxyribose (found in DNA) and ribose (found in RNA). One or more phosphate groups. [1] The nitrogen bases adenine and guanine are purine in structure and form a glycosidic bond between their 9 nitrogen and the 1' -OH group of the deoxyribose.
