Description

Etofibrate is the ethandiol-1,2 diester of the nicotinic and clofibric acids. Etofibrate has been shown to be a potent hypolipidemic agent in animal and human.

In Vivo

Etofibrate is the ethandiol-1,2 diester of the nicotinic and clofibric acids. Etofibrate has been shown to be a potent hypolipidemic agent in animal and human. After 10 days of treatment with Etofibrate, the rats show a body weight similar to that found in the control animals but their liver weight is significantly enhanced whereas plasma cholesterol and triacylglycerol levels are decreased. Etofibrate treatment increases the bile flow of the animals, the effect being especially manifest during the first 2 hr after interruption of the enterohepatic circulation and the difference with the controls becomes statistically significant at 30 and 90 min. The cumulative amount of bile secreted plotted against time shows a highly significant linear correlation for both control and Etofibrate treated rats, the slope being significantly higher for the Etofibrate group than for controls[1].

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (6.87 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (6.87 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Animal Administration
[1]

Male Sprague Dawley rats weighing 200 to 220 g, fed ad libitum a standard laboratory diet and subjected to a 12 hr on-off light cycle and 22 to 24°C are used. Food is removed from the cages at the onset of the light cycle (7.00 a.m.) and 3 hr later, Etofibrate is administered by stomach tube without anesthesia at a dose of 300 mg/kg body weight/day to one group of animals whereas another, control, group is treated with the medium. After treatments, rats are again allowed free access to food. On the 10th day, the animals are treated as above, but 2 hr after receiving the Etofibrate or the medium the rats are anesthetized with an intraperitoneal injection (0.30 mL/100 g body weight). Animals are maintained at 37°C in a thermostatically controlled cabinet[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
