Compounds (20)

CompoundDescription
melatoninA biogenic amine that is found in animals and plants. In mammals, melatonin is produced by the PINEAL GLAND. Its secretion increases in darkness and decreases during exposure to light. Melatonin is implicated in the regulation of SLEEP, mood, and REPRODUCTION. Melatonin is also an effective antioxidant.
sapropterinRN given refers to parent cpd; co-factor required for catalytic activity of nitric oxide synthases
picolinic acidiron-chelating agent that inhibits DNA synthesis; may interfere with iron-dependent production of stable free organic radical which is essential for ribonucleotide reductase formation of deoxyribonucleotides; RN given refers to parent cpd; structure in Merck Index, 9th ed, #7206
quinolinic acidA metabolite of tryptophan with a possible role in neurodegenerative disorders. Elevated CSF levels of quinolinic acid are correlated with the severity of neuropsychological deficits in patients who have AIDS.
DinoprostoneThe most common and most biologically active of the mammalian prostaglandins. It exhibits most biological activities characteristic of prostaglandins and has been used extensively as an oxytocic agent. The compound also displays a protective effect on the intestinal mucosa.
anthranilic acidRN given refers to parent cpd; structure in Negwer, 5th ed, #565
glutaryl-coenzyme a
kynurenic acidA broad-spectrum excitatory amino acid antagonist used as a research tool.
crotonyl-coenzyme a
xanthurenic acid
NADA coenzyme composed of ribosylnicotinamide 5'-diphosphate coupled to adenosine 5'-phosphate by pyrophosphate linkage. It is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH). (Dorland, 27th ed)
3-hydroxyanthranilic acidAn oxidation product of tryptophan metabolism. It may be a free radical scavenger and a carcinogen.
3-hydroxykynurenineRN given refers to cpd without isomeric designation
N'-formylkynureninea photochemical breakdown product of tryptophan in proteins; RN given refers to parent cpd without isomeric designation
glutaconyl-coenzyme A
cinnabarinic acidstructure
nicotinic acid adenine dinucleotideintermediate in the biosynthesis of NAD
acetyl coenzyme aAcetyl CoA participates in the biosynthesis of fatty acids and sterols, in the oxidation of fatty acids and in the metabolism of many amino acids. It also acts as a biological acetylating agent.
kynurenineA metabolite of the essential amino acid tryptophan metabolized via the tryptophan-kynurenine pathway.
