O-Phosphotyrosine
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).

Flumequine
Ciprofloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria. It functions by inhibiting DNA gyrase, a type II topoisomerase, and topoisomerase IV, enzymes necessary to separate bacterial DNA, thereby inhibiting cell division. Flumequine is a 9-fluoro-6,7-dihydro-5-methyl-1-oxo-1H,5H-benzo[ij]quinolizine-2-carboxylic acid. The molecular formula is C14H12FNO3 It is a white powder, odorless, flavorless, insoluble in water but soluble in organic solvent. Flumequine is a synthetic chemotherapeutic antibiotic of the fluoroquinolone drug class used to treat bacterial infections. It is a first-generation fluoroquinolone antibacterial that has been removed from clinical use and is no longer being marketed. It kills bacteria by interfering with the enzymes that cause DNA to unwind and duplicate. Flumequine was used in veterinarian medicine for the treatment of enteric infections (all infections of the intestinal tract), as well as to treat cattle, swine, chickens, and fish, but only in a limited number of countries. It was occasionally used in France (and a few other European Countries) to treat urinary tract infections under the trade name Apurone. However this was a limited indication because only minimal serum levels were achieved. The first quinolone used was nalidixic acid (was marketed in many countries as Negram) followed by the fluoroquinolone flumequine. The first-generation fluoroquinolone agents, such as flumequine, had poor distribution into the body tissues and limited activity. As such they were used mainly for treatment of urinary tract infections. Flumequine (benzo quinolizine) was first patented in 1973, (German Patent) by Rikker Labs. Flumequine is a known antimicrobial compound described and claimed in U.S. Pat. No. 3,896,131 (Example 3), July 22, 1975. Flumequine is the first quinolone compound with a fluorine atom at the C6-position of the related quinolone basic molecular structure. Even though this was the first fluoroquinolone, it is oftentimes overlooked when classifying the drugs within this class by generations and excluded from such a list. There continues to be considerable debate as to whether or not this DNA damage is to be considered one of the mechanisms of action concerning the severe adverse reactions experienced by some patients following fluoroquinolone therapy.

2-Methoxyacetaminophen sulfate
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
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).
