C11H16N5O5+ (298.1151)

7-methylguanosine 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. 7-Methylguanosine is a substrate for purine-nucleoside phosphorylase and Eukaryotic translation initiation factor 4E.

2-Phenylethanol glucuronide

(2S,3S,4S,5R,6R)-3,4,5-trihydroxy-6-(2-phenylethoxy)oxane-2-carboxylic acid

C14H18O7 (298.1052)

2-Phenylethanol glucuronide is a natural human metabolite of 2-phenylethanol generated in the liver by UDP glucuonyltransferase. Glucuronidation is used to assist in the excretion of toxic substances, drugs or other substances that cannot be used as an energy source. Glucuronic acid is attached via a glycosidic bond to the substance, and the resulting glucuronide, which has a much higher water solubility than the original substance, is eventually excreted by the kidneys.
