Gamma-glutamylglutamine
N2-gamma-Glutamylglutamine, also known as gamma-L-Glu-L-Gln or L-gamma-glutamyl-L-glutamine, belongs to the class of organic compounds known as dipeptides. These are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. N2-gamma-Glutamylglutamine is a very strong basic compound (based on its pKa). N2-gamma-Glutamylglutamine is a dipeptide obtained from the condensation of the gamma-carboxy group of glutamic acid with the alpha-amino group of glutamine. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. gamma-Glutamylglutamine has been identified in plasma and cerebrospinal fluid from hyperammonaemic patients. [HMDB] H-γ-Glu-Gln-OH is a hydrophilic peptide and can be conjugated to drugs. The carrier composed of H-γ-Glu-Gln-OH has the characteristics of high water solubility and drug-loading capacity, good biocompatibility, low toxicity, improved tumor targeting ability, and anti-tumor efficacy[1].

Glutamylglutamine
Glutamylglutamine is a dipeptide composed of glutamate and glutamine, and is a proteolytic breakdown product of larger proteins. It belongs to the family of N-acyl-alpha amino acids and derivatives. These are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. Glutamylglutamine 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.

Ethenodeoxyadenosine
Etheno nucleosides are a new class of chemically modified components of nucleic acids. These base-modified nucleosides demonstrate significant biological properties, acting, among others, as antiviral or antitumor agents. One of the possible modifications of the nucleoside is their transformation into ethenonucleosides. Thus, nucleosides or their respective heterocyclic bases, possessing an exocyclic amino group, as well as a neighboring endocyclic nitrogen, can react with some bifunctional reagents (e.g., α-halocarbonyl compounds) to form products with an additional five-membered ring of the imidazole type. The ethenonucleosides basically do not occur in nature; some of the only exceptions are Y-nucleosides. Etheno modified DNA bases are generated from the carcinogens vinyl chloride and urethane, but also by reactions of DNA with products derived from lipid peroxidation (LPO) and oxidative stress via endogenous pathways. Highly variable background levels of epsilon-adducts were detected in DNA from different organs of unexposed humans and rodents. Several known cancer risk factors increased the level of these DNA lesions in target organs: elevated epsilon-adducts were found in hepatic DNA from patients with metal storage diseases, after overproduction of nitric oxide (NO) by inducible NO synthase (iNOS) in a mouse model, and in colonic polyps of familial adenomatous polyposis patients. A high omega-6-polyunsaturated fatty acid diet increased epsilon-DNA adducts in white blood cells of female subjects. (PMID:10882861).

Glutamyl-Gamma-glutamate
Glutamyl-Gamma-glutamate is a dipeptide composed of glutamate and gamma-glutamate. 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.
