Carglumic acid

(2S)-2-(Carbamoylamino)pentanedioic acid

Carglumic acid is an orphan drug used for the treatment of hyperammonaemia in patients with N-acetylglutamate synthase deficiency. This rare genetic disorder results in elevated blood levels of ammonia, which can eventually cross the blood-brain barrier and cause neurologic problems, cerebral edema, coma, and death. Carglumic acid was approved by the U.S. Food and Drug Administration (FDA) on 18 March 2010.

3-Dehydroquinic acid

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

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.
