Modified 5-fluorouracil: Uridine phosphorylase inhibitor

Аннотация

5-Fluorouracil (5-FU) is a medication widely used in chemotherapy to treat various types of cancer. Being a substrate for the reverse reaction catalyzed by uridine phosphorylase (UPase), 5-FU serves as a promising prototype molecule (molecular scaffold) for the design of a selective UPase inhibitor that enhances the antitumor activity of 5-FU and exhibits intrinsic cytostatic effects on cancer cells. The chemical formula of the new compound, which binds to the uracil-binding site and, in the presence of a phosphate anion, to the phosphate-binding site of UPase, is proposed and investigated by molecular simulation methods.
