Queuine

2-Amino-5-((((1S,4S,5R)-4,5-dihydroxy-2-cyclopenten-1-yl)amino)methyl)-1,7-dihydro-4H-pyrrolo(2,3-D)pyrimidin-4-one

C12H15N5O3 (277.1175)


Queuine is a highly modified derivative of guanine found in the first position of the anticodon of the transfer RNAs for asp, asn, his and tyr. The original transcripts of these tRNAs contain guanine in this position. All organisms with the exception of yeast and mycoplasma contain queuine. Bacteria synthesize queuine but it cannot be synthesized by higher mammals. Significant amounts of free queuine are present in common plant and animal food products.

S-(2-Methylpropionyl)-dihydrolipoamide-E

[Dihydrolipoyllysine-residue (2-methylpropanoyl)transferase]S-(2-methylpropanoyl)dihydrolipoyllysine

C12H23NO2S2 (277.117)


S-(2-Methylpropionyl)-dihydrolipoamide-E is an intermediate in valine, leucine and isoleucine degradation(KEGG ID C15977). It is the second to last step in the synthesis of branched chain fatty acid and is converted from 2-methyl-1-hydroxypropyl-ThPP via the enzyme 2-oxoisovalerate dehydrogenase [EC:1.2.4.4]. It is then converted to isobutyryl-CoA via the enzyme dihydrolipoyllysine-residue (2-methylpropanoyl)transferase [EC:2.3.1.168].

Entecavir

2-amino-9-[(1S,3R,4S)-4-hydroxy-3-(hydroxymethyl)-2-methylidenecyclopentyl]-6,9-dihydro-3H-purin-6-one

C12H15N5O3 (277.1175)


Entecavir is an oral antiviral drug used in the treatment of hepatitis B infection. It is marketed under the trade name Baraclude (BMS). Entecavir is a guanine analogue that inhibits all three steps in the viral replication process, and the manufacturer claims that it is more efficacious than previous agents used to treat hepatitis B (lamivudine and adefovir). It was approved by the U.S. Food and Drug Administration (FDA) in March 2005.

Arginylcysteine

(2R)-2-{[(2S)-2-amino-5-carbamimidamido-1-hydroxypentylidene]amino}-3-sulphanylpropanoic acid

C9H19N5O3S (277.1209)


Arginylcysteine is a dipeptide composed of arginine and cysteine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis.

   

Cysteinyl-Arginine

C9H19N5O3S (277.1209)


Cysteinyl-Arginine is a dipeptide composed of cysteine and arginine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.

Fructose aminoacids are naturally occurring compounds derived from D-fructose and L-aminoacids. They are amadori products resulting from sugar-aminoacid interactions in food products, especially cooked foods [CCD] N-(1-Deoxy-1-fructosyl)proline is classified as a Natural Food Constituent (code WA) in the DFC.
