In vitro

Mycophenolate mofetil is an ester prodrug of the active immunosuppressant mycophenolic acid (MPA). The latter shows a noncompetitive, selective and reversible inhibition activity against inosine monophosphate dehydrogenase type I/II with IC50 of 39 nM and 27 nM, respectively. Moreover, MPA also produces the concentration-dependent inhibition of proliferation of ConA-stimulated T cells, LPS-stimulated B cells and alloantigen-specific T cells with IC50 of 100 nM, 120 nM, and 51 nM, respectively. This compound with high concentration of 10 μg/mL induces a strong apoptosis in microglial cell cultures and increases the number of activated caspase-3 immunoreactive apoptotic cells. In addition, it (1 μg/mL) strongly inhibits proliferation of both microglial cells and astrocytes. A recent study shows that this chemical significantly attenuates the extent of neuronal cell death of organotypic hippocampal slice cultures after neuronal injury in a time-dependent manner.

Kinase Assay
IMP dehydrogenase Types I and II enzymatic activity
IMP dehydrogenase Types I and II are purified from E. coli expressing human enzymes. The assay is performed using a flat bottom, UV-transparent 96-well plate. The final 200 μL reaction mixture contained 0.1 M Tris, 0.1 M KCl, 3 mM EDTA pH 8.0, 2 mM DTT, and 40 nM of either IMP dehydrogenase Type I or Type II. The reaction is initiated by adding 400 μM NAD and 400 μM IMP, followed by incubation at 37 °C for 2.5 hours. The reaction rate of the conversion of NAD to NADH is then measured based on the increase in absorbance at 340 nm. The assays are also performed in the presence of 50% human serum to estimate serum protein binding by different IMP dehydrogenase inhibitors.
In vivo

In an ACI-to-Lewis rat heterotopic cardiac transplant model, treatment of Mycophenolate mofetil at doses of 20 mg/kg and 40 mg/kg leads to a prolongation of graft survival, with median survival time (MST) of 14.5 days and 18.5 days, respectively. In bleomycin (BLM)-induced scleroderma mouse model, this compound reduces inflammatory-cell infiltration, tissue hydroxyproline content and dermal thickness.
