| Common Name | 6-O-Desmethyl-mycophenolic acid |
|---|
| Description | 6-O-Desmethyl-mycophenolic acid belongs to the class of organic compounds known as hydroxybenzoic acid derivatives. Hydroxybenzoic acid derivatives are compounds containing a hydroxybenzoic acid (or a derivative), which is a benzene ring bearing a carboxyl and a hydroxyl groups. 6-O-Desmethyl-mycophenolic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). 6-O-Desmethyl-mycophenolic acid is a metabolite of mycophenolic acid. It inhibits an enzyme needed for the growth of T cells and B cells. 6-O-desmethyl-mycophenolic acid and formaldehyde can be biosynthesized from mycophenolic acid; which is catalyzed by the enzymes cytochrome P450 3A4, cytochrome P450 3A5, and cytochrome P450 2C8. In humans, 6-O-desmethyl-mycophenolic acid is involved in mycophenolic acid metabolism pathway. It was initially marketed as the prodrug mycophenolate mofetil (MMF) to improve oral bioavailability. Mycophenolic acid or mycophenolate is an immunosuppressant drug used to prevent rejection in organ transplantation. Mycophenolic acid is commonly marketed under the trade names CellCept and Myfortic. More recently, the salt mycophenolate sodium has also been introduced. |
