Pharmacodynamics

Merimepodib, an oral drug, contains a novel inhibitor of inosine monophosphate dehydrogenase (IMPDH), an enzyme responsible for stimulating the production of lymphocytes. Merimepodib has the potential to exert direct antiviral activity, as well as affect the immune response by acting on lymphocyte migration and proliferation. Consequently, merimepodib may be an effective treatment for hepatitis C virus (HCV) infection, as the disease involves both viral proliferation and liver inflammation.

Mechanism of action

Merimepodib is a orally active inhibitor of inosine monophospate dehydrogenase (IMPDH). IMPDH inhibition leads to a reduction in intracellular guanosine triphosphate (GTP), a molecule required for DNA and RNA synthesis.
