5-benzylacyclouridine

Uses

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].

Definition

ChEBI: A pyrimidone that is uracil which is substituted by a 2-hydroxyethoxymethyl group at position 1 and a benzyl group at position 5.
