Product Description

Clofibric acid (BRN-1874067; CCRIS 9254; BRN1874067; NSC 1149; NSC1149; Chlorofibrinic acid), the active metabolite of clofibrate, etofibrate and theofibrate (the lipid-lowering drugs), is a potent PPARα agonist and anti-hyperlipidemic agent.

Biological Activity I Assay Protocols (From Reference)
ln Vitro

In vitro activity: Clofibric acid increases CYP4A6 gene expression in RK13 cells transfected with PPAR-G with EC50 of 80 μM. Clofibric acid (1 mM) treatment for 4 days induces 500-fold increase of P450 4Al RNA and 280-fold increase of acyl-CoA oxidase and P450 2Bl RNA in hepatocytes, relative to control cultures. Clofibric acid (250 μM) induces up-regulation of genes involved in peroxisome proliferation and in cell proliferation as well as down-regulation of genes involved in apoptosis in hepatocytes of rodent. Clofibric acid treatment is able to cause up-regulation of L-fatty acid binding protein (L-FABP) gene in hepatocytes of both rodent and human origin. Clofibric acid also up-regulates genes expression of the cytosolic, microsomal, and mitochondrial pathways involved in fatty acid transport and metabolism in both rodent and human hepatocyte cultures, and increases genes level of the peroxisomal pathway of lipid metabolism in rodents. An up-regulation of hepatocyte nuclear factor 1α (HNF 1α) by Clofibric acid is observed in human hepatocyte cultures. Clofibric acid also dose-dependently inhibits cell proliferation of cultured OVCAR-3 and DISS cells derived from human ovarian cancer. Clofibric acid treatment increases the expression of carbonyl reductase, which promotes the conversion of prostaglandin E2 (PGE2) to PGF 2α.

ln Vivo
Clofibric acid (50 mg/kg) treatment 4 days by gavage induces both P450 4A and BFB expression in zones 3 and 2 of the liver acinus in rats. 300 mg/kg of Clofibric acid causes a strong staining of both proteins throughout the liver acinus. Clofibric acid (9,000 ppm) treatment in diet significantly suppresses the growth of OVCAR-3 tumors xenotransplanted s.c. (46%) and significantly prolongs the survival of mice with malignant ascites derived from DISS cells as compared with control. Clofibric acid treatment increases the expression of carbonyl reductase in vivo. Clofibric acid treatment decreases PGE2 level as well as vascular endothelial growth factor (VEGF) amount in both of OVCAR-3–tumor and DISS-derived ascites. Reduced microvessel density and induced apoptosis are in solid OVCAR-3 tumors treated by Clofibric acid.

Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (11.65 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.5 mg/mL (11.65 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
