Background:

Benzylacyclouridine (BAU) is a potent and specific inhibitor of uridine phosphorylase, the first enzyme in the catabolism of uridine. Benzylacyclouridine can modulate the cytotoxic side effects of 5-fluorouracil (5-FU) and its derivatives[1][2][3].

Benzylacyclouridine increases 5-FU-induced cytotoxicity in a number of human cancer cell lines[1].Benzylacyclouridine (20-100 μM) reduces the rapid clearance of trace amounts of either [14C]uridine or hyperphysiologic concentrations of non-labeled uridine by the isolated rat liver perfused with an artificial oxygen carrier[2].

Benzylacyclouridine (p.o. or i.v.) arrests the rapid degradation of a tracer dose of uridine into uracil in dogs and pigs[1].Benzylacyclouridine exhibits the t1/2 of 1.8-3.6 h in dogs, with bioavailability levels of 85% (30 mg/kg) and 42.5% (120 mg/kg)[1].Benzylacyclouridine (120 mg/kg) exhibits the t1/2 of 1.6-2.3 h, with a bioavailability of 40% in pigs[1].
