3-Dehydroquinic acid

(1R,3R,4S)-1,3,4-trihydroxy-5-oxocyclohexane-1-carboxylic acid

C7H10O6 (190.04773600000001)

3-Dehydroquinic acid belongs to the class of organic compounds known as alpha-hydroxy acids and derivatives. These are organic compounds containing a carboxylic acid substituted with a hydroxyl group on the adjacent carbon. 3-Dehydroquinic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). In most organisms, 3-dehydroquinic acid is synthesized from D-erythrose-4-phosphate in two steps. However, archaea genomes contain no orthologs for the genes that encode these first two steps. Instead, archaeabacteria appear to utilize an alternative pathway in which 3-dehydroquinic acid is synthesized from 6-deoxy-5-ketofructose-1-phosphate and L-aspartate-semialdehyde. These two compounds are first condensed to form 2-amino-3,7-dideoxy-D-threo-hept-6-ulosonate, which cyclizes to 3-dehydroquinic acid. From 3-dehydroquinic acid and on to chorismate, the archaeal pathway appears to be identical to the bacterial pathway.

Nitroxoline

Nitroxoline, potassium salt

C9H6N2O3 (190.0378406)

Nitroxoline is only found in individuals that have used or taken this drug. It is a urinary antibacterial agent active against susceptible gram-positive and gram-negative organisms commonly found in urinary tract infections. It is a fluorquinolone that is active against bacterial gyrases.This drug may also have antitumor activity by inhibition of ype 2 methionine aminopeptidase (MetAP2) protein which is involved in angiogenesis. Its antibacterial activity may stem from the metal ion complexation vital for bacterial growth.

2-O-Methylascorbic acid

(5R)-5-[(1S)-1,2-dihydroxyethyl]-4-hydroxy-3-methoxy-2,5-dihydrofuran-2-one

C7H10O6 (190.047736)

2-O-Methylascorbic acid (2-O-MA) is a derivative of vitamin C (ascorbic acid). The enzyme catechol-O-methyltransferase catalyzes the methylation of L-ascorbic acid into 2-O-methylascorbic acid (PMID: 7129800). 2-O-Methylascorbic acid belongs to the class of organic compounds known as butenolides. These are dihydrofurans with a carbonyl group at the C2 carbon atom. 2-O-Methylascorbic acid has been identified in urine and was found to be higher in older women than in younger women (PMID: 28813537).
