Terbufibrol
Based on 1 Customer Validation
Terbufibrol is an orally active lipid-lowering agent. Terbufibrol inhibits hepatic Cholesterol 7 alpha-hydroxylase. Terbufibrol blocks a step between Acetate and HMG-CoA in the hepatic cholesterol synthesis process. Terbufibrol reduces serum total cholesterol, HDL, LDL, lipoprotein levels, and the cholesterol/phospholipid ratio, with dose- and sex-dependent changes in lipoprotein components. Terbufibrol exerts sustained cholesterol-lowering activity in baboons and rats. Terbufibrol can be used in research related to hypercholesterolemia.

Cholesterol 7 alpha-hydroxylase |
Terbufibrol (20-200 mg/kg/day; p.o.; daily; 4 weeks) dose-dependently reduces serum total cholesterol and modulates lipoprotein cholesterol levels in HPF-diet induced endogenous hypercholesterolemic male baboons, with a maximum 80% serum TC reduction at 200 mg/kg/day and an ED50 of 60 mg/kg/day specific to this diet model[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:Papio cynocephalus (2-3 years old, 4-7 kg, equal numbers of males and females)[1]
-
Dosage:12 mg/kg/day; 50 mg/kg/day; 200 mg/kg/day
-
Administration:p.o.; daily; 8 weeks
-
Result:Reduced serum total cholesterol by 6.7% after 8 weeks at 12 mg/kg/day.
Decreased VLDL by a mean of 20% and HDL by a mean of 21% respectively at 12 mg/kg/day.
Increased LDL in males by 36% at 12 mg/kg/day.
Reduced serum total cholesterol by 21.1% after 8 weeks at 50 mg/kg/day.
Decreased VLDL by a mean of 12% and HDL by a mean of 43% at 50 mg/kg/day.
Decreased LDL in males by 35% at 50 mg/kg/day.
Reduced serum total cholesterol by 69.1% after 8 weeks at 200 mg/kg/day.
Reduced total lipoprotein by a mean of 52% across sexes at 200 mg/kg/day.
Decreased LDL by a mean of 46% and HDL by a mean of 57% at 200 mg/kg/day.
Reduced LDL-TC and HDL-TC, with a greater effect on LDL-TC, increasing the HDL-TC/LDL-TC ratio by 56% compared to control at 200 mg/kg/day.
Caused a dose-related decrease in the TC/PL ratio in VLDL due to increased PL content.
Caused a dose-related decrease in the TC/PL ratio in LDL due to reduced TC content and increased TG content.
Caused a trend of decreased PL with increasing dose in HDL.

Animal Model:Papio cynocephalus (2-3 years old, 4-7 kg, male only)[1]
-
Dosage:20 mg/kg/day; 60 mg/kg/day; 200 mg/kg/day
-
Administration:p.o.; daily; 4 weeks
-
Result:Primarily decreased HDL-TC, reducing the HDL-TC/LDL-TC ratio by 17% at 20 mg/kg/day.
Decreased LDL-TC more than HDL-TC, increasing the HDL-TC/LDL-TC ratio from a control value of 1.8 to 4.4 (a 144% increase) at 60 mg/kg/day.
Produced a maximum 80% reduction in serum TC at 200 mg/kg/day.
Decreased LDL-TC more than HDL-TC, and also reduced HDL, HDL-TC, LDL, and LDL-TC/PL at 200 mg/kg/day.
Was approximately 10 times more active than clofibrate at reducing serum TC in this model.
Had an ED50 for serum TC reduction of 60 mg/kg/day for the HPF-diet.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
