luridine

L-Uridine is the enantiomer of D-uridine, a nucleoside that acts as a phosphate acceptor for nucleoside phosphotransferase, in the normal RNA component of a normal RNA isolated from Polyporaceae fungus Poria cocos (Schw.) L-Uridine has potential antiviral activity.

5-Methyluridine (Thymine riboside) is an endogenous methylated nucleoside found in human fluids; methylated purine bases are present in higher amounts in tumor-bearing patients compared to healthy controls.DNA hypermethylation is a common finding in malignant cells and has been explored as a therapeutic target for hypomethylating agents.

3-Methyluridine is a modified nucleoside of cellular RNA.

2′-O-Methyluridine is a natural product that found in RNA such as rRNA, snRNA, snoRNA and tRNA in Archaea, Bacteria, and Eukaryota.
