      Carmofur is a derivative of fluorouracil, an antimetabolite used as an antineoplastic agent. ;Target: Nucleoside antimetabolite/analogCarmofur, which is used in the clinic to treat colorectal cancers, is a potent AC inhibitor and that this property is essential to its anti-proliferative effects. Carmofur inhibited AC activity with a median effective concentration (IC50) of 29 ? 5 nM (mean ? standard error of the mean, s.e.m.; n = 4), whereas 5-FU had no such effect (IC50>1 mM). systemic administration of carmofur (10 or 30 mg-kg-1, intraperitoneal, i.p.) to mice produced a dose-dependent inhibition of AC activity in various tissues, including lungs and brain cortex.
