Description: Etofibrate, the ethandiol-1,2 diester of the nicotinic and clofibric acid, is a combination of conjugated clofibrate and niacin that is used to treat hyperlipemia. Etofibrate treatment heightens the cytosolic glycerol-3-phosphate dehydrogenase activity and the total carnitine concentration in the liver of rats, whereas it reduces triacylglycerol and cholesterol concentrations. Etofibrate decreases plasma levels of cholesterol, triacylglycerols, free fatty acids (FFA) and glycerol, as well as the total and unesterified cholesterol concentrations, in liver microsomes of rats.

ProtocolIn VitroIn vitro activity: Etofibrate treatment heightens the cytosolic glycerol-3-phosphate dehydrogenase activity and the total carnitine concentration in the liver of rats, whereas it reduces triacylglycerol and cholesterol concentrations. Etofibrate decreases plasma levels of cholesterol, triacylglycerols, free fatty acids (FFA) and glycerol, as well as the total and unesterified cholesterol concentrations, in liver microsomes of rats. Etofibrate increases the activity of liver cytosolic glycerol-3-P dehydrogenase in the rats, whereas it decreases the activity of both microsomal HMG-CoA reductase and cholesterol 7 alpha-hydroxylase and does not affect acyl-CoA: cholesterol acyltransferase (ACAT). Etofibrate decreases the availability of lipolytic products in the liver by acting on their release from adipose tissue and on their intrinsic hepatic metabolism. Etofibrate stimulates the rate of fatty acid re-esterification when incubations are done under basal conditions in epididymal fat pad pieces from fed rats.
In VivoEtofibrate (1.2 mM/g) decreases plasma FFA levels in male Sprague-Dawley rats, Etofibrate enhances or decreases plasma glycerol levels depending on both the dose and the time after treatment. Etofibrate (200 mg/kg) causes a significant inhibition of the proliferation of the smooth muscle cells in the intimal proliferate which consequently results in a less pronounced plaque in a rabbit model of atherosclerosis.
Animal modelMale Sprague Dawley rats

Method for preparing DMSO master liquid: mg drug pre-dissolved in µL DMSO(Master liquid concentration mg/mL) ,Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation: Take µL DMSO master liquid, next add µL PEG300, mix and clarify, next add µL Tween 80,mix and clarify, next add µL ddH2O,mix and clarify.
Note:
  • (1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
  • (2) Be sure to add the solvent(s) in order.
