Homogentisic acid
Homogentisic acid, also known as melanic acid, is an intermediate in the breakdown or catabolism of tyrosine and phenylalanine. It is generated from the compound p-hydroxyphenylpyruvate through the enzyme p-hydroxyphenylpyruvate dehydrogenase. The resulting homogentisic acid is then broken down into 4-maleylacetoacetate via the enzyme homogentisate 1,2-dioxygenase. Homogentisic acid is also found in other organisms. For instance, it can found in Arbutus unedo (strawberry-tree) honey, in the bacterial plant pathogen Xanthomonas campestris as well as in the yeast Yarrowia lipolytica where it is associated with the production of brown pigments. Homogentisic acid can be oxidatively dimerized to form hipposudoric acid, one of the main constituents of the blood sweat of hippopotamuses. When present in sufficiently high levels, homogentisic acid can function as an osteotoxin and a renal toxin. An osteotoxin is a substance that causes damage to bones and/or joints. A renal toxin causes damage to the kidneys. Chronically high levels of homogentisic acid are associated with alkaptonuria (OMIM: 203500), an inborn error of metabolism. Alkaptonuria is a rare inherited genetic disorder in which the body cannot process the amino acids phenylalanine and tyrosine. It is caused by a mutation in the enzyme homogentisate 1,2-dioxygenase (EC 1.13.11.5), which leads to an accumulation of homogentisic acid in the blood and tissues. Homogentisic acid and its oxidized form benzoquinone acetic acid are excreted in the urine, giving it an unusually dark color. The accumulating homogentisic acid (and benzoquinone acetic acid) causes damage to cartilage (ochronosis, leading to osteoarthritis) and heart valves as well as precipitating as kidney stones and stones in other organs. More specifically, homogentisic acid can be converted to benzoquinone acetic acid (BQA), and the resulting BQA can be readily converted to polymers that resemble the dark skin pigment melanin. These polymers are deposited in the collagen, a connective tissue protein, of particular tissues such as cartilage. This process is called ochronosis (as the tissue looks ochre); ochronotic tissue is stiffened and unusually brittle, impairing its normal function and causing damage. Homogentisic acid is the primary precursor of melanin synthesis in Vibrio cholerae. 2-(3,6-dihydroxyphenyl)acetic acid, also known as homogentisic acid or homogentisate, is a member of the class of compounds known as 2(hydroxyphenyl)acetic acids. 2(hydroxyphenyl)acetic acids are phenylacetic acids that carry a hydroxyl group at the 2-position. 2-(3,6-dihydroxyphenyl)acetic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). 2-(3,6-dihydroxyphenyl)acetic acid can be found in a number of food items such as gooseberry, angelica, chinese broccoli, and cucumber, which makes 2-(3,6-dihydroxyphenyl)acetic acid a potential biomarker for the consumption of these food products. 2-(3,6-dihydroxyphenyl)acetic acid can be found primarily in blood, feces, and urine, as well as in human cartilage, connective tissue and kidney tissues. In humans, 2-(3,6-dihydroxyphenyl)acetic acid is involved in few metabolic pathways, which include disulfiram action pathway, phenylalanine and tyrosine metabolism, and tyrosine metabolism. 2-(3,6-dihydroxyphenyl)acetic acid is also involved in several metabolic disorders, some of which include dopamine beta-hydroxylase deficiency, tyrosinemia type 3 (TYRO3), alkaptonuria, and tyrosinemia type 2 (or richner-hanhart syndrome). Moreover, 2-(3,6-dihydroxyphenyl)acetic acid is found to be associated with alkaptonuria. 2-(3,6-dihydroxyphenyl)acetic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Apart from treatment of the complications (such as pain relief using NSAIDs and joint replacement for the cartilage damage), vitamin C has been used to reduce the ochronosis and lowering of the homogentisic acid levels may be attempted with a low-protein diet. Recently the drug nitisinone has been found to suppress homogentisic acid production. Nitrisinone inhibits the enzyme, 4-hydroxyphenylpyruvate dioxygenase, responsible for converting tyrosine to homogentisic acid, thereby blocking the production and accumulation of homogentisic acid. Nitisinone treatment has been shown to cause a 95\\\\% reduction in plasma and urinary homogentisic acid (T3DB). Acquisition and generation of the data is financially supported in part by CREST/JST.

Etodolac
Etodolac is only found in individuals that have used or taken this drug. It is a non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic and antipyretic properties. Its therapeutic effects are due to its ability to inhibit prostaglandin synthesis. It is indicated for relief of signs and symptoms of rheumatoid arthritis and osteoarthritis. Similar to other NSAIDs, the anti-inflammatory effects of etodolac result from inhibition of the enzyme cycooxygenase (COX). This decreases the synthesis of peripheral prostaglandins involved in mediating inflammation. Etodolac binds to the upper portion of the COX enzyme active site and prevents its substrate, arachidonic acid, from entering the active site. Etodolac was previously thought to be a non-selective COX inhibitor, but it is now known to be 5 – 50 times more selective for COX-2 than COX-1. Antipyresis may occur by central action on the hypothalamus, resulting in peripheral dilation, increased cutaneous blood flow, and subsequent heat loss.

2-Hydroxybenzaldehyde
2-Hydroxybenzaldehyde, also known as salicylal or O-formylphenol, belongs to the class of organic compounds known as hydroxybenzaldehydes. These are organic aromatic compounds containing a benzene ring carrying an aldehyde group and a hydroxyl group. 2-Hydroxybenzaldehyde is a cinnamon, cooling, and medical tasting compound. 2-Hydroxybenzaldehyde is found, on average, in the highest concentration within peppermints. 2-Hydroxybenzaldehyde has also been detected, but not quantified, in several different foods, such as common buckwheats, garden tomato (var.), herbs and spices, and tea. This could make 2-hydroxybenzaldehyde a potential biomarker for the consumption of these foods. 2-Hydroxybenzaldehyde is a potentially toxic compound. Present in cinnamon (Cinnamomum versum). Flavouring ingredient. 2-Hydroxybenzaldehyde is found in many foods, some of which are garden tomato (variety), herbs and spices, common buckwheat, and tea.
