Description

MKC9989 is a Hydroxy aryl aldehydes (HAA) inhibitor and also inhibits IRE1α with an IC50 of 0.23 to 44 μM.

IC50 & Target

IC50: 0.23 to 44 μM (IRE1α)[1]
In Vitro

At 10 μM concentration, MKC9989 completely inhibits both basal and thapsigargin induced splicing of XBP1 mRNA. These effects are observed even in cells pre-treated with thapsigargin, indicating that MKC9989 can fully reverse the onset of XPB1 splicing after the UPR is initiated. In parallel analysis, MKC9989, significantly stabilizes the RIDD target CD59 mRNA when co-administered with thapsigargin relative to thapsigargin treatment alone and modestly increases levels of CD59 mRNA in non-stressed cells, the latter likely reflects the inhibition of baseline RIDD activity. In contrast to effects on XBP1 splicing, MKC9989 moderately stabilizes CD59 levels when administered 2 hour post treatment with thapsigargin. Finally, the potency of MKC9989 against the splicing of XBP1 mRNA (EC50=0.33 μM) is comparable to its potency against RNA cleavage in vitro[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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (7.43 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.

Human RPMI 8226 plasmacytoma cells are grown in monolayer culture using medium (DMEM) supplemented with 10% fetal calf serum (FCS) at 37°C and 5% CO2. MKC9989 is prepared as 10 mM stocks in DMSO, stored at -20°C, and diluted in medium. Thapsigargin (Tg) is resuspended in DMSO and diluted in medium. Cells are grown to 50% confluency, treated with 1 μM Tg and/or 10 μM MKC9989 at the indicated time points. After incubation of cells for the indicated periods, cells are harvested[1].

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.
