Biological Activity

Description Etofibrate is a combination of clofibrate and niacin, used to treat hyperlipemia.
In vitro
In vitro 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. [1] 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. [2] Etofibrate stimulates the rate of fatty acid re-esterification when incubations are done under basal conditions in epididymal fat pad pieces from fed rats. [3]
In Vivo
In vivo Etofibrate (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. [3] 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.

Working concentration: mg/ml;

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 addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
