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.

Sample Use Guides

In Vivo Use Guide

Orally 300-500 mg/m2 daily for 6 weeks for advanced gastrointestinal cancer treatment

Route of Administration: Oral

In Vitro Use Guide

When exposed for 24 h to carmofur (1–100 mM), AC-overexpressing HEK 293 cells showed a markedly reduced ceramide accumulation and cell death relative to control cells subjected to the same treatment.
