Description

Ertiprotafib is an inhibitor of PTP1B, IkB kinase β (IKK-β), and a dual PPARα and PPARβ agonist, with an IC50 of 1.6 μM for PTP1B, 400 nM for IKK-β, an EC50 of ~1 μM for PPARα/PPARβ.

IC50 & Target[1][2]

PTP1B

1.6 μM (IC50)

IKK-β

400 nM (IC50)

PPARα

~1 μM (EC50)

PPARβ

~1 μM (EC50)

In Vitro

Ertiprotafib is a potent inhibitor of IKK-β, with an IC50 value of 400±40 nM, which is much lower than that required for the half-maximal inhibition of the p-nitrophenyl phosphatase activity of PTP1B. The reported IC50 value of Ertiprotafib against PTP1B ranges from 1.6 to 29 μM depending on the assay conditions[2]. Ertiprotafib is at least a dual PPARα and PPARβ agonist with EC50 values for transactivation of 1 μM. Such activities readily explain the observations with suprapharmacologic doses of these[1].

In Vivo

As seen with treatment of ob/ob mice, both Ertiprotafib and compound 3 seem to significantly improve glucose metabolism in rats. At 25 mg/kg/day, these compounds decrease both fasting blood glucose and insulin levels compared with vehicle treated rats. Furthermore, both Ertiprotafib and compound 3 increase glucose disposal after an oral challenge. It is noteworthy that lipid levels are also reduced in treated animals. Both triglyceride and free fatty acid levels are substantially reduced in rats treated with 25 mg/kg/day of either compound. To summarize, both Ertiprotafib and compound 3 seem to be robust agents in improving glucose utilization in fa/fa rats while also decreasing lipid levels in these animals. Decreased lipid levels may be unexpected for a pure PTP1b inhibitor. It is more telling, as mentioned above, that rats treated with suprapharmacologic doses of Ertiprotafib show signs of PPAR family activation[2].

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 (4.47 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 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% Corn Oil

    Solubility: ≥ 2.5 mg/mL (4.47 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Mice, Rats[2]
Male Ob/ob mice and Zucker fa/fa rats are used. They are kept on a 12-h/12-h light/dark cycle and fed Rodent Diet 5001 (for mice and rats) from Purina Mills. Compounds are dosed orally by gavage in an aqueous suspension of 2% Tween 80 and 0.5% methylcellulose. Whole blood (5 μL) is used for glucose readings via tail nick for measurement using the Ascensia Elite XL glucometer and glucose strips by preloading a strip into the meter and touching the end to a small drop of blood on each tail. Insulin levels are quantified by enzyme-linked immunosorbent assay[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.
