Description

ML67-33 is a selective activator of temperature- and mechano-sensitive K2P channels. ML67-33 rapidly and reversibly affects K2P2.1 (TREK-1) with EC50s of 36.3 μM and 9.7 μM in cell-free and HEK293 cells, respectively[1].

IC50 & Target

EC50: 36.3 μM (K2P2.1 (TREK-1)), 9.7 μM (K2P2.1 (TREK-1), in HEK293 cells)[1].
In Vitro

ML67-33 activates K2P channels and mutants with EC50s of 21.8±1.3 μM, 49.4±1.1 μM, 30.2±1.4 μM, and 27.3±1.2 μM for K2P2.1 (TREK-1) W275S, K2P2.1 (TREK-1)-3G, K2P10.1 (TREK-2), K2P4.1 (TRAAK), respectively[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    90% Corn Oil

    Solubility: ≥ 1.25 mg/mL (3.34 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 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 (12.5 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.
