Biological Activity

Description Mycophenolic acid is a potent IMPDH inhibitor and the active metabolite of an immunosuppressive drug, used to prevent rejection in organ transplantation.
In vitro

Mycophenolic acid inhibits inosine-5'-monophosphate dehydrogenase (IMPDH) by acting as a replacement for the nicotinamide portion of the nicotinamide adenine dinucleotide cofactor and a catalytic water molecule. [1] Mycophenolic acid (MPA), an inhibitor of inosine monophosphate dehydrogenase, in nanomolar concentrations blocks proliferative responses of cultured human, mouse and rat T lymphocytes and B lymphocytes to mitogens or in mixed lymphocyte reactions. Mycophenolic acid (MPA) suppresses mixed lymphocyte reactions when added 3 days after their initiation. Mycophenolic acid also inhibits antibody formation by polyclonally activated human B lymphocytes. Mycophenolic acid is an immunosuppressive agent reversibly inhibiting proliferation of T and B lymphocytes and antibody formation, with a profile of activity different from that of other immunosuppressive drugs. [2] Mycophenolic acid inhibits the formation of antibodies to sheep erythrocytes. Mycophenolic acid also suppresses, in a dose-related manner, the generation of cytotoxic T-lymphocytes against allogeneic cells in mice and prevents the elimination of allogeneic cells. [3] Mycophenolic acid induces apoptosis and cell death in a large proportion of activated CD4+ T cells. [4]

In vivo Mycophenolic acid has lymphocyte-selective anti-proliferative effects in mice and can inhibit both cell-mediated and humoral immune responses without major side effects. [3]

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*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

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 )

  • C1

* 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.
