Metabolite Identification

Common Name

N-(2-Carboxymethyl)-morpholine

Description

N-(2-Carboxymethyl)-morpholine belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). N-(2-Carboxymethyl)-morpholine is a very strong basic compound (based on its pKa). Within humans, N-(2-carboxymethyl)-morpholine participates in a number of enzymatic reactions. In particular, N-(2-carboxymethyl)-morpholine, N-(2-hydroxyethyl)-morpholine, and N-(2-hydroxyethyl)-morpholine N-oxide can be biosynthesized from mycophenolate mofetil; which is mediated by the enzyme cocaine esterase. In addition, N-(2-carboxymethyl)-morpholine, N-(2-hydroxyethyl)-morpholine, and N-(2-hydroxyethyl)-morpholine N-oxide can be biosynthesized from mycophenolate mofetil; which is mediated by the enzymes liver carboxylesterase 1 and cocaine esterase. In humans, N-(2-carboxymethyl)-morpholine is involved in mycophenolic acid metabolism pathway. N-(2-Carboxymethyl)-morpholine is a metabolite of mycophenolate mofetil. Mycophenolate mofetil (MMF) (brand names CellCept, Myfortic) is an immunosuppressant and prodrug of mycophenolic acid, used extensively in transplant medicine. MMF is a less toxic alternative to azathioprine. It is a reversible inhibitor of inosine monophosphate dehydrogenase (IMPDH) in purine biosynthesis which is necessary for the growth of T cells and B cells. Other cells are able to recover purines via a separate, scavenger, pathway and are, thus, able to escape the effect.
