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.

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.

Cysteinyl-Histidine
Cysteinyl-Histidine is a dipeptide composed of cysteine and histidine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.
Histidylcysteine
Histidylcysteine is a dipeptide composed of histidine and cysteine. It is an incomplete breakdown product of protein digestion or protein catabolism. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis.
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.
