Biological Activity

Description Gemfibrozil is an activator of peroxisome proliferator-activated receptor-alpha (PPARα), used for the treatment of hypercholesterolemia and hypertriglyceridemia.
PPARα [1]
In vitro

Gemfibrozil exerts a minimal inhibitory effect on CYP3A-mediated simvastatin hydroxy acid (SVA) oxidation, but does inhibit SVA glucuronidation in dog and human liver microsomes. [1] Gemfibrozil markedly inhibits M-23 formation, with a K(i) (IC(50)) value of 69 (95) mM, whereas inhibition of M-1 formation is weaker with a K(i) (IC(50)) value of 273 mM in human liver microsomes. [2] Gemfibrozil strongly and competitively inhibits CYP2C9 activity, with a K(i) (IC(50)) value of 5.8 (9.6) mM. Gemfibrozil exhibits somewhat smaller inhibitory effects on CYP2C19 and CYP1A2 activities, with K(i) (IC(50)) values of 24 (47) mM and 82 (136) mM, respectively. [3] Gemfibrozil, a lipid-lowering drug, inhibits cytokine-induced production of NO and the expression of inducible nitric-oxide synthase (iNOS) in human U373MG astroglial cells and primary astrocytes. Gemfibrozil induces peroxisome proliferator-responsive element (PPRE)-dependent luciferase activity, which is inhibited by the expression of DeltahPPAR-alpha, the dominant-negative mutant of human PPAR-alpha. Gemfibrozil strongly inhibits the activation of NF-kappaB, AP-1, and C/EBPbeta but not that of gamma-activation site (GAS) in cytokine-stimulated astroglial cells. [4]

In vivo Gemfibrozil treatment significantly reduces (2-3-fold) the plasma clearance of SVA and the biliary excretion of SVA glucuronide (together with its cyclization product SV), but not the excretion of a major oxidative metabolite of SVA in dogs. [1]

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.
