Uridine 5'-diphosphate sodium salt is a selective native agonist of the P2Y6 receptor (EC50: 300 nM; pEC50: 6.52) and a potent antagonist of P2Y14 (pEC50: 7.28).

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.

2'-Deoxyuridine (2-deoxyuridine). An antimetabolite that is converted to deoxyuridine triphosphate during DNA synthesis. Laboratory suppression of deoxyuridine is used to diagnose megaloblastic anemias due to vitamin B12 and folate deficiencies.

3-Methyluridine is a modified nucleoside of cellular RNA.

Pseudouridine is the most abundant modified nucleoside in non-coding RNAs. It enhances the function of transfer RNA and ribosomal RNA by stabilizing RNA structure.

2'-Deoxyuridine 5'-monophosphate disodium (2'-dUMP⋅2Na) salt is utilized by the enzyme thymidylate synthetase (TS) for the de novo synthesis of dTMP and serves as the reference substrate in studies of dUMP analogues for potential chemotherapy applications.

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

5,6-Dihydrouridine, a modified base, is located in conserved positions within the D-loop of tRNA in Eukaryota, Bacteria, and some Archaea.

Cytidine 5'-diphosphate trisodium salt (CDP) catalyzes the production of Cytidine triphosphate (CTP) for DNA and RNA synthesis by transferring a phosphoryl group from ATP to cytidine monophosphate (CMP) through the action of uridine monophosphate kinase (UMPK).

2'-Deoxycytidine-5'-monophosphoric acid (2'-Deoxycytidine 5'-monophosphate) is a substrate of uridine monophosphate (UMP) cytidine monophosphate (CMP) kinase (EC 2.7.4.4) that forms dCDP, which, upon phosphorylation to dCTP, supports DNA biosynthesis.

Pyrimidine (Metadiazine)s are heterocyclic, six-membered, nitrogen-containing carbon ring structures, with uracil, cytosine and thymine being the basal structures of ribose-containing nucleosides (uridine, cytidine, and thymidine respectively), or deoxyribose-containing deoxynucleosides, and their corresponding ribonucleotides or deoxyribonucleotides. Pyrimidines serve essential functions in human metabolism as ribonucleotide bases in RNA (uracil and cytosine), and as deoxyribonucleotide bases in DNA (cytosine and thymine), and are linked by phosphodiester bridges to purine nucleotides in double-stranded DNA, in both the nucleus and the mitochondria. Pyrimidine activated sugars are also involved in polysaccharide and phospholipid synthesis, glucuronidation in detoxification processes, glycosylation of proteins and lipids and in the recently identified novel endothelium-derived vasoactive dinucleotides.
