Miscellaneous Organic Molecules with Isotopical Substitutions

Applications L-3-Phosphoglyceric Acid 13C3 Sodium Salt is a carbon-13 labelled Sodium salt form of  L-3-Phosphoglyceric Acid. 3-Phosphoglyceric acid is involved in glutamate biosynthesis in syntrophus aciditrophicus. Also used in the studies of pyruvate carboxylation in SDH-deficient kidney mouse cells. References Kim, M., et al.: Appl. Environ. Microbiol. 81, 8434 (2015); Cardaci, S., et al.: Nat. Cell. Biol. 17, 1317 (2015)

Applications A metabolite of Vitamin D. The principal circulating form of vitamin D3, formed in the liver by hydroxylation at C-25. Calcium regulator. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References orii, et al.: Arch. Biochem. Biophys., 120, 513 (1967), Blunt, et al.: Biochemistry, 7, 3317 (1968), Liu, et al.: Science, 311, 1770 (2006),

Applications Labelled 1-Butanamine (B689735), which is used in the preparation of 5-HT6 receptor antagonists affecting the concentrations of dopamine and norephinephrine. May be used in the treatment of the neurological degenerative disease, Alzheimer’s. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Upton, N. et al.: Neurotherapeu. 5, 458 (2008); Ivachtchenko, A. et al.: Pharm. Chem. J., 46, 639 (2013);

Stability Hygroscopic Applications Labelled Dipyrone. Dipyrone is a non-steroidal anti-inflammatory drug that, when coadministered with morphine, potentiates its antinociceptive action and delays the development of tolerance. Dipyrone is a relatively selective inhibitor of cyclooxygenase-3 (COX-3), with lower activity against COX-1 and no activity against COX-2. Dipyrone blocks PGE2-induced hyperalgesia in several models.

Sci., 171, 115 (1999); Schwarz, S. et al.: Neurology, 2000, 54, 354 (2000); Greer, D. et al.: Stroke, 39, 3029 (2008);

Applications L-Citrulline-d7, is the labeled analogue of L-Citrulline (C535700), which is an amino acid, first isolated from the juice of watermelon, Citrullus vulgaris Schrad., Cucurbitaceae. It is also used in the treatment of asthenia. References Kurtz, et al.: J. Biol. Chem., 122, 477 (1938), Rajantie, J., et al.: J. Pediatr., 97, 927 (1980), Carpenter, T.O., et al.: N. Engl. J.
