Mechanism of action
The mechanism of action of carmofur is traditionally thought to be the generation of 5–FU. However, carmofur is a highly potent acid ceramidase (AC) inhibitor. Ceramide influences cancer cell survival, growth and death. Inhibition of AC activity sensitizes tumor cells to the effects of antineoplastic agents and radiation.
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.
As fluorouracil, carmofur has been known to induce leukoencephalopathy.
