Carmofur, also known as 5-fluoro-N-hexyl-2,4-dioxo-pyrimidine-1-carboxamide and as 1-hexylcarbamoyl-5-fluorouracil, is a pyrimidine analogue which acts as an antineoplastic agent through inhibition of thymidylate synthase. It has been used in the treatment of breast and colorectal cancer. Carmofur is approved in Japan for the treatment of cancer.
