Ribothymidine
Ribothymidine 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. When chemical bonds to DNA, the DNA becomes damaged and proper and complete replication cannot occur to make the normal intended cell. A DNA adduct is an abnormal piece of DNA covalently-bonded to a cancer-causing chemical. This has shown to be the start of a cancerous cell, or carcinogenesis. DNA adducts in scientific experiments are used as bio-markers and as such are themselves measured to reflect quantitatively, for comparison, the amount of cancer in the subject.

Imidazoleacetic acid riboside
Imidazoleacetic acid riboside is a metabolite of imidazoleacetic acid (itself histamines oxidative metabolite). (PMID: 7616240). In kidney glomeruli, histamine is predominantly catabolized to acid metabolites of the diamine oxidase (histaminase) pathway, imidazoleacetic acid and Imidazoleacetic acid riboside. (PMID: 7616240). Imidazoleacetic acid riboside is a metabolite of imidazoleacetic acid (itself histamines oxidative metabolite). (PMID: 7616240)

3-Methyluridine
3-Methyluridine is a modified nucleoside of cellular RNA. All modifications are formed post-transcriptionally in RNA from the normal nucleosides by modifying enzymes, especially specific RNA-methyltransferases and RNA-synthetases. Due to the lack of specific phosphorylases for modified nucleosides they cannot be recycled for synthesizing RNA, so they are excreted quantitatively in urine.

2'-O-Methyluridine
2-O-Methyluridine belongs to the class of organic compounds known as pyrimidine nucleosides. Pyrimidine nucleosides are compounds comprising a pyrimidine base attached to a ribosyl or deoxyribosyl moiety. 2-O-Methyluridine was identified as one of forty plasma metabolites that could be used to predict gut microbiome Shannon diversity (PMID: 31477923). Shannon diversity is a metric that summarizes both species abundance and evenness, and it has been suggested as a marker for microbiome health.
