Description

Pemafibrate is a highly selective PPARα agonist, with an EC50 of 1 nM.

IC50 & Target

EC50: 1 nM (h-PPARα), 1.10 μM (h-PPARγ), 1.58 μM (h-PPARδ)[1]
In Vitro

Pemafibrate is a potent PPARα agonist, with EC50s of 1 nM, 1.10 μM and 1.58 μM for h-PPARα, h-PPARγ and h-PPARδ, respectively. Pemafibrate is more than 1000 fold selective towards PPARα than PPARγ and PPARδ[1].

In Vivo

Pemafibrate (3 mg/kg, p.o.) increases plasma h-apoA-I in human apoA-I (h-apoA-I) transgenic mice, and shows higher levels of plasma h-apoA-I than fenofibrate at 300 mg/kg[1]. Pemafibrate (0.03 mg/kg) decreases levels of triglycerides and aspartate aminotransferase (AST) in PEMA-L (db/db) mice. Pemafibrate (0.1 mg/kg) not only shows such effects but increases liver weight in PEMA-H (db/db) mice. Pemafibrate enhances the pathogenesis in a rodent model of nonalcoholic steatohepatitis (NASH). Pemafibrate significantlly reduces the grade of hepatocyte ballooning in PEMA-H mice. Furthermore, Pemafibrate modulates lipid turnover and induces uncoupling protein 3 (UCP 3) expression in the liver[2]. Pemafibrate (K-877, 0.0005%) contained in high-fat diet (HFD) inhibits the body weight gain in mice. Pemafibrate significantly decreases the abundance of triglyceride (TG)-rich lipoproteins, including remnants, in postprandial plasma of mice. Pemafibrate also decreases intestinal mRNA expression of ApoB and Npc1l1[3].

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 (5.10 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 (5.10 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    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
[2]

Mice are fasted for 12 h and fasting blood glucose measured. Nine-week-old db/db mice are used in the assay. After a 2-week acclimatization period, mice are divided into four groups: BD (db/db) mice (fed basal diet (BD) and treated with 0.5% aqueous methylcellulose solution (MC); MCD (db/db) mice (fed methionine choline-deficient (MCD) and treated with 0.5% MC); PEMA-L (db/db) mice (fed MCD and treated with 0.03 mg/kg Pemafibrate); PEMA-H (db/db) mice (fed MCD and treated with 0.1 mg/kg Pemafibrate). The drug-free solvent or the dosing solution is administered to animals (5 mL/kg body weight, p.o.) once daily (in the morning) for 4 consecutive weeks. After a 2-week acclimatization period, BD mice are fed a BD for 20 weeks. CTRL mice are fed D09100301 for 20 weeks. PEMA-L and PEMA-H mice are fed D09100301 for 12 weeks followed by D09100301 with 0.4 mg and 1.3 mg Pemafibrate/kg of the diet for 8 weeks, which corresponds to 0.03 mg/kg/day and 0.1 mg/kg/day, respectively. FENO mice are fed D09100301 for 12 weeks followed by D09100301 with 666.7 mg fenofibrate/kg of the diet for 8 weeks, which corresponds to 50 mg/kg/day. Pemafibrate and fenofibrate are incorporated into the AMLN diet. Animals are housed under conventional conditions with controlled temperature, humidity, and light (12-h light-dark cycle) and provided with food and water[2].

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.
