Esomeprazole sodium  (Synonyms: (S)-Omeprazole sodium; (-)-Omeprazole sodium)

Cat. No.: HY-17023 Purity: 99.35%
COA Handling Instructions

Esomeprazole sodium ((S)-Omeprazole sodium) is a potent and orally active proton pump inhibitor. Esomeprazole reduces acid secretion through inhibition of the H+, K+-ATPase in gastric parietal cells. Esomeprazole acts as an exosome inhibitor by blocking the exosome release via the inhibition of V-H+-ATPases. Esomeprazole has the potential for symptomatic gastroesophageal reflux disease research.

Description

Esomeprazole sodium ((S)-Omeprazole sodium) is a potent and orally active proton pump inhibitor. Esomeprazole reduces acid secretion through inhibition of the H+, K+-ATPase in gastric parietal cells. Esomeprazole acts as an exosome inhibitor by blocking the exosome release via the inhibition of V-H+-ATPases[4]. Esomeprazole has the potential for symptomatic gastroesophageal reflux disease research[1][2][3].

IC50 & Target

H+, K+-ATPase[1][2]

In Vitro

Esomeprazole (25-100 µM; 20 hours; MDA-MB-468 cells) treatment suppresses growth of triple-negative breast cancer cell in vitro in a dose-dependent manner through increase in their intracellular acidification[1].

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

Cell Viability Assay[1]

Cell Line: MDA-MB-468 cells
Concentration: 25 µM, 50 µM, 75 µM, 100 µM
Incubation Time: 20 hours
Result: Suppressed growth of triple-negative breast cancer cell in vitro in a dose-dependent manner.
In Vivo

Esomeprazole (30-300 mg/kg; oral gavage; daily; for 19 or 11 days; C57BL/6J mice) treatment significantly inhibits the progression of fibrosis throughout the lungs of the animals. Esomeprazole also reduces circulating markers of inflammation and fibrosis[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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (5.66 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 (5.66 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.

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.
