Carmofur (INN) or HCFU (1-hexylcarbamoyl-5-fluorouracil) is a pyrimidine analogue used as an antineoplastic agent. It is a derivative of fluorouracil.
Mechanism of action
The mechanism of action of carmofur is traditionally thought to be the generation of 5–FU.[1] However, carmofur is a highly potent acid ceramidase (AC) inhibitor.[1] Ceramide influences cancer cell survival, growth and death.[1] Inhibition of AC activity sensitizes tumor cells to the effects of antineoplastic agents and radiation.[1]
Uses
Carmofur, in its oral form, has also been used as adjuvant chemotherapy for curatively resected colorectal cancer patients. Trials and meta-analyses have confirmed that the drug is effective on patients with this cancer type, extending their survival.[2]
Adverse effects
As fluorouracil, carmofur has been known to induce leukoencephalopathy.[3][4][5]
