Methionyl-Asparagine

2-{[2-amino-1-hydroxy-4-(methylsulphanyl)butylidene]amino}-3-(C-hydroxycarbonimidoyl)propanoic acid

C9H17N3O4S (263.0939722)


Methionyl-Asparagine is a dipeptide composed of methionine and asparagine. 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.

Creatine riboside

N-(N-((2R,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)carbamimidoyl)-N-methylglycine

C9H17N3O6 (263.1117302)


Creatine riboside is a conjugate between creatine and ribose. It is a novel diagnostic marker for lung cancer that is elevated in the urine of non-small cell lung cancer subjects (PMID: 24736543). Creatine riboside may be a product of both high creatine levels within tumor cells and the characteristic high phosphate flux of cancer cells. Increased mutagenicity of creatine and ribose pyrolysis products in cooked foods has been reported, suggesting a functional role of creatine riboside in tumorigenesis (PMID: 24736543). Creatine riboside is likely not an enzyme-synthesized product as it can be formed spontaneously by mixing creatine with ribose. It can be synthesized in modestly high yields by reacting ribose and creatine in the presence of ammonium bicarbonate and heating the two compounds at 80°C for 10 minutes.
