Metabolite Identification

Common Name

N-(2-Hydroxyethyl)-morpholine N-oxide

Description

N-(2-Hydroxyethyl)-morpholine N-oxide belongs to the class of organic compounds known as morpholines. These are organic compounds containing a morpholine moiety, which consists of a six-member aliphatic saturated ring with the formula C4H9NO, where the oxygen and nitrogen atoms lie at positions 1 and 4, respectively. Other cells are able to recover purines via a separate, scavenger, pathway and are, thus, able to escape the effect. N-(2-Hydroxyethyl)-morpholine N-oxide is a metabolite of mycophenolate mofetil. N-(2-Hydroxyethyl)-morpholine N-oxide is an extremely weak basic (essentially neutral) compound (based on its pKa). Within humans, N-(2-hydroxyethyl)-morpholine N-oxide 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 catalyzed by the enzymes liver carboxylesterase 1 and cocaine esterase. In humans, N-(2-hydroxyethyl)-morpholine N-oxide is involved in mycophenolic acid metabolism pathway. 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. 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.
