Mizoribine (Bredinin, NSC 289637) is an imidazole nucleoside and an immunosuppressant that inhibits HCV RNA replication with IC50 of ~ 100 μM for anti-HCV activity. Mizoribine is a selective inhibitor of inosine-5'-monophosphate dehydrogenase (IMPDH) and guanosine monophosphate synthetase. Mizoribine also inhibits SARS-CoV.

| Targets |

| 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. [1] 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. [2] Mizoribine inhibits HCV RNA replication with IC50 of 100 μM. [3] |

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

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
