Description

Mizoribine (Bredinin, NSC 289637,HE 69) is an imidazole nucleoside and an immunosuppressant that inhibits with IC50 of ~ 100 μM for anti-HCV activity. Mizoribine is a selective inhibitor of and . Mizoribine also inhibits SARS-CoV.

Targets

Monophosphate synthetase ^[2]

In vitro

Mizoribine (1-50 mg/mL) is able to inhibit T cell proliferation by 10-100% in a dose-dependent fashion to all stimuli tested. Mizoribine leads to a decrease in intracellular GTP levels, and that repletion of GTP reversed its antiproliferative effects. Mizoribine causes a dose-dependent inhibition of T cell proliferation, which is reversible with the addition of 50 mM guanosine to replete guanine ribonucleotide pools. Mizoribine selectively inhibits guanine ribonucleotide formation in purified T cells, whereas the effect of 6-mercaptopurine (6MP) appears to be more dependent on adenine ribonucleotide depletion. Mizoribine inhibits HCV RNA replication with IC50 of 100 μM.
