Mizoribine DNA/RNA Synthesis inhibitor

Mizoribine is an imidazole nucleoside and an immunosuppressant that inhibits HCV RNA replication with IC50 of ~ 100 μM for anti-HCV activity. This compound is a selective inhibitor of inosine-5'-monophosphate dehydrogenase (IMPDH) and guanosine monophosphate synthetase. It also inhibits SARS-CoV.

In vitro

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. This compound leads to a decrease in intracellular GTP levels, and that repletion of GTP reversed its antiproliferative effects. [1] It causes a dose-dependent inhibition of T cell proliferation, which is reversible with the addition of 50 mM guanosine to replete guanine ribonucleotide pools. This chemical 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. [2] It inhibits HCV RNA replication with IC50 of 100 μM. [3]

In Vivo

In vivo

Mizoribine (5 or 10 mg/kg) suppresses urinary albumin excretion in the rats. This compound inhibits the development of glomerulosclerosis, interstitial fibrosis and macrophage infiltration in the kidney in the rats. It increases the expression of MCP-1, OPN and TGF-β1 mRNA in untreated OLETF rats. [4]

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
