Description

PD-118057 is a hERG channel activator without causing hERG blockade. PD-118057 activates hERG channel to suppress changes in membrane excitability[1][2].

IC50 & Target

Human ether-a-go-go-related gene channel[1]
In Vitro

PD-118057 (3 μM and 10 μM) specifically increases hERG current and inhibits action potential duration in guinea pig ventricular muscle in acute isolation of guinea pig cardiomyocytes[2][3].
PD-118057 (10 μM) reverses the current inhibition induced by Dof and Mox without changing the "hump" shape of IKr current recorded by action potential clamp, and only slightly increases the peak value of the suppressed current[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (6.47 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.

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.
