O-Phosphotyrosine

(2S)-2-amino-3-[4-(phosphonooxy)phenyl]propanoic acid

C9H12NO6P (261.0402222)

O-Phosphotyrosine is a phosphorylated amino acid that occurs in a number of proteins. Tyrosine phosphorylation and dephosphorylation plays a role in cellular signal transduction and possibly in cell growth control and carcinogenesis. Small amounts of free phosphotyrosine can be found in urine (PMID: 7693088). Levels of this amino acid appear to be elevated in mammalian urine during liver regeneration (PMID: 7516161). Phosphotyrosine is also able to induce platelet aggregation in vitro and it has been suggested that free phosphotyrosine in blood could be meaningful for in vivo platelet activation (PMID: 1282059).

Dehydrogenated ticlopidine

5-[(2-Chlorophenyl)methyl]-4,5-dihydrothieno[3,2-c]pyridine

C14H12ClNS (261.0378942)

Dehydrogenated ticlopidine is only found in individuals that have used or taken Ticlopidine. Dehydrogenated ticlopidine is a metabolite of Ticlopidine. Dehydrogenated ticlopidine belongs to the family of Thienopyridines. These are heterocyclic compounds containing a thiophene ring fused to a pyridine ring.

2-Methoxyacetaminophen sulfate

4-(Acetylamino)-3-methoxyphenyl hydrogen sulphuric acid

C9H11NO6S (261.03070660000003)

2-Methoxyacetaminophen sulfate, also known as 4-(acetylamino)-3-methoxyphenyl hydrogen sulfate, is a member of the class of compounds known as phenylsulfates. Phenylsulfates are compounds containing a sulfuric acid group conjugated to a phenyl group. 2-Methoxyacetaminophen sulfate is practically insoluble (in water) and an extremely strong acidic compound (based on its pKa).

O-Sulfotyrosine

(2S)-2-Amino-3-[4-(sulphooxy)phenyl]propanoic acid

C9H11NO6S (261.03070660000003)

O-Sulfotyrosine belongs to the class of organic compounds known as phenylalanine and derivatives. Phenylalanine and derivatives are compounds containing phenylalanine or a derivative thereof resulting from a reaction of phenylalanine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. O-Sulfotyrosine has been identified as a potential plasma biomarker of reduced kidney function in early chronic kidney disease (CKD), end stage renal disease (ESRD), and hemodialytic clearance (PMID: 31048706). Human plasma levels of O-sulfotyrosine were reported to be influenced by genetic variants in the gene ARSA which codes for the enzyme arylsulfatase A (PMID: 24816252).
