Description

Coumberone is a metabolic fluorogenic probe, and isoform-selective substrate for all AKR1C isoforms. Coumberone can be reduced by all four members of the AKR1C family to its fluorescent alcohol coumberol. Coumberone can be used for the research of AKR1C[1][2].

In Vitro

Coumberone (30 μM; 24 hours; HCT116 cells) is an AKR1C3 substrate and demonstrates maximal rates at ~10 μM[1]. Coumberone (5 μM; 24 hours; COS-1 cells) can be used for the selective optical readout of each isoform, either AKR1C2 or AKR1C3[2]. Coumberone (5 μM; 24 hours; IMR32 cells) enables real-time imaging of AKR1C induction[2]. Coumberone (80 hours; IMR-32 cells) metabolism is indeed increased. Coumberone exhibits 10-fold greater catalytic efficiency for AKR1C3 than AKR1C2 in vitro[2].

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% (20% SBE-β-CD in Saline)

    Solubility: ≥ 1.67 mg/mL (4.84 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

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.
