Description and Uses

5-Methyluridine is a pyrimidine nucleoside and methylated form of uridine. It is the ribonucleoside counterpart to the deoxyribonucleoside thymidine, which lacks a hydroxyl group at the 2' position. 5-Methyluridine contains a thymine base joined to a ribose pentose sugar. It is an endogenous methylated nucleoside found in human fluids. In cells, 5-methyluridine is present in tRNA, formed during its post-transcriptional modification by the methylation of uridine.

A primary degradation product of tRNA, an urinary nucleoside as biological marker for patients with colorectal cancer.
It enhances the antitumor activity of 5-fluorouracil in a mouse Erlich solid carcinoma model and a P388 murine leukemia model. It has been used to characterize the activity of a variety of enzymes, including uridine nucleosidase.
