Esomeprazole magnesium ((S)-Omeprazole magnesium) is a potent and orally active H+, K+-ATPase inhibitor. Esomeprazole magnesium has the potential for upper intestinal disorders and gastroesophageal reflux disease research. Esomeprazole magnesium acts as an exosome inhibitor by blocking the exosome release via the inhibition of V-H+-ATPases.

Description

Esomeprazole magnesium ((S)-Omeprazole magnesium) is a potent and orally active H+, K+-ATPase inhibitor. Esomeprazole magnesium has the potential for upper intestinal disorders and gastroesophageal reflux disease research[1][2]. Esomeprazole magnesium acts as an exosome inhibitor by blocking the exosome release via the inhibition of V-H+-ATPases[4].

IC50 & Target

H+, K+-ATPase[1]
In Vitro

Esomeprazole magnesium is an inhibitor of H+, K+-ATPase[1].Esomeprazole magnesium is develped from Esomeprazole strontium tetrahydrate (EST). EST contains esomeprazole, the S-enantiomer of omeprazole a salt-exchanged version of Esomeprazole magnesium trihydrate[3].

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: ≥ 2.08 mg/mL (2.92 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (2.92 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

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.
