Description

4′-Demethylnobiletin is a bioactive metabolite that activates the PKA/ERK/CREB signaling pathway, enhances CRE-mediated transcription in hippocampal neurons, and reverses memory impairment associated with NMDA receptor antagonism by stimulating ERK signaling[1].

In Vitro

4′-Demethylnobiletin (1-100 μM, 0-60 min) can activate the phosphorylation of ERK and CREB in rat hippocampal neurons in a time- and concentration-dependent manner, and in a PKA/MEK/ERK pathway-dependent manner, It can also stimulate CRE-mediated transcription by activating PKA/MEK/ERK-dependent signaling pathways[1].

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

In Vivo

4′-Demethylnobiletin (10 or 50 mg/kg, ip, once daily for seven consecutive days) dose-dependently reverses MK-801-induced learning impairment in male ddY mice without affecting the mice's mobility . Mice treated with MK-801 shows less freezing than control mice and induced inhibition of ERK learning activation in the hippocampus of mice, which is also reversed by 4′-Demethylnobiletin[1].
4′-Demethylnobiletin (10 or 50 mg/kg, ip, once daily for seven consecutive days) reverses the inhibition of MK-801 on NMDA-stimulated phosphorylation of ERK and PKA substrates in hippocampal neurons[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 (6.44 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2.5 mg/mL.

    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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: 2.5 mg/mL (6.44 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2.5 mg/mL. 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.
