T-705RMP, the phosphorylated metabolite derived from T-705, demonstrates a limited inhibitory impact on the host cells' IMP dehydrogenase (IMPDH) activities, with an IC 50 value of 601 μM.
Mycophenolic acid sodium is a potent uncompetitive inhibitor of inosine monophosphate dehydrogenase (IMPDH), exhibiting an EC50 of 0.24 μM. It has broad antiviral activity against RNA viruses, including influenza. Additionally, mycophenolic acid sodium possesses immunosuppressive properties and exerts antiangiogenic and antitumor effects [1][2].
