title: Mycophenolic acid analogs with a modified metabolic profile.
abstract: Mycophenolic acid (MPA), a clinically used immunosuppressant, is extensively metabolized into an inactive C7-glucuronide and removed from circulation. To circumvent the metabolic liability imposed by the C7-hydroxyl group, we have designed a series of hybrid MPA analogs based on the pharmacophores present in MPA and new generations of inosine monophosphate dehydrogenase (IMPDH) inhibitors. The synthesis of MPA analogs has been accomplished by an allylic substitution of a common lactone. Biological evaluations of these analogs and a preliminary structure-activity relationship (SAR) are presented.
