Description

Trametiglue, a derivative of Trametinib (HY-10999), targets both KSR-MEK and RAF-MEK with unprecedented potency and selectivity via unique interfacial binding interactions[1].

IC50 & Target[1]

MEK1

 

MEK2

 

In Vitro

Trametiglue retains the strong binding potency and residence time of Trametinib on KSR-bound MEK[1].
Trametiglue, unlike Trametinib but similar to Avutometinib (HY-18652), enhances interactions between endogenous BRAF and MEK1[1].
Trametiglue (1 μM) demonstrates high selectivity towards MEK1 and MEK2 in direct binding assays. Trametiglue also displays high selectivity in a panel of active kinases measured for inhibition of MEK1 and MEK2 substrate phosphorylation or direct MEK1 phosphorylation by the upstream kinases[1].
Trametiglue (5 days) inhibits HCT116, A375, A549 and SK-MEL-239 cells viability with IC50s of 0.07, 0.07, 0.12 and 0.47 nM, respectively[1].
Trametiglue (10 nM; 10 days) inhibits colony formation in KRAS-mutant and BRAF-mutant cancer cell lines with higher potency than Trametinib[1].

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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (3.75 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.

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.
