Biochem/physiol Actions

Cyclopentenyl uracil is a non-cytotoxic inhibitor of uridine kinase that act as a potent inhibitor of pyrimidine salvage in the intact mouse. Combination of Cyclopentenyl uracil with GSK983 significantly reduces viral infection of dengue serotype 2 (DENV-2) strain 16681 in cultures of the A549 lung carcinoma cell line. Cyclopentenyl uracil in combination with GSK983 enhances therapeutic index of viral RdRp inhibitor R1479.

Genome-wide analysis of the mode of action of GSK983, a potent antiviral agent, led to the identification of dihydroorotate dehydrogenase as its target along with the discovery that genetic knockdown of pyrimidine salvage sensitized cells to GSK983. Because GSK983 is an

Cyclopentenyl uracil, a non-cytotoxic inhibitor of uridine kinase, was found to effectively block the salvage of circulating uridine by host and tumor tissues in the intact mouse. Dose-response characteristics of the inhibition were determined. Large doses (1 g/kg) of cyclopentenyl
