Mycophenolic Acid, also referred to as MPA, is a potent inhibitor of the enzyme inosine 5’-monophosphate dehydrogenase (IMPDH), a key molecule in the biosynthesis of guanine nucleotides. This inhibition leads to suppression of pro-inflammatory cytokines, nitric oxide, and LDH in macrophages (1). Mycophenolic Acid has been shown to inhibit the reproduction of the Middle East respiratory syndrome coronavirus (MERS-CoV) with an IC50 of 2.87 µM (2). Clinically, Mycophenolic Acid has been used as an anti-rejection immunosuppressant medication for kidney and liver transplant patients (3,4).
