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.

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.
In RNA, uracil binds with a ribose sugar to form the ribonucleoside uridine. When a phosphate attaches to uridine, uridine 5′-monophosphate is produced. [6] Uracil undergoes amide-imidic acid tautomeric shifts because any nuclear instability the molecule may have from the lack of formal aromaticity is compensated by the cyclic-amidic ...
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 ...
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. Cytosine, thymine, and uracil are pyrimidines, hence the glycosidic bonds
Inside the centennial time capsule, officials found 15 artifacts dating back to 1924 and earlier, including a film of the 1921 groundbreaking for the memorial, the 1917 Declaration of War and a ...
