Clear solution
5% DMSO 95% Corn oil
1.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 20 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 10% PEG 300 5%Tween80 80%ddH2O
10.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 200 mg/ml clarified DMSO stock solution to 100 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 800 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Lansoprazole (A-65006, AG-1749) is a proton-pump inhibitor (PPI) that binds covalently to parietal cell H(+),K(+)-ATPase. Lansoprazole prevents the stomach from producing gastric acid.
Targets
Proton pump [1] H(+),K(+)-ATPase [1]
In vitro Lansoprazole inhibits gastric acid secretion via inhibition of gastric hydrogen/potassium adenosine triphosphatase (H+,K(+)-ATPase), an enzyme of the gastric parietal cell membrane that forms part of the proton pump that performs the final step in the acid secretory process. Lansoprazole binds covalently to parietal cell H+,K(+)-ATPase, rendering it nonfunctional and inhibiting the secretion of gastric acid. [1] Lansoprazole is a strong anti-secretory agent that acts on gastric H+/K+-adenosine triphosphatase (H+/K+ ATPase) of parietal cells. Lansoprazole inhibits the increased expression of vascular adhesion molecules, the activation of neutrophils, and the production of pro-inflammatory cytokines from activated endothelial cells. Lansoprazole induces several genes, including phase II detoxifying enzyme (NADPH-ubiquinone oxidoreductase, glutathione S-transferase) and antioxidant stress proteins (HO-1, thioredoxin reductase, and superoxide dismutase) in gastric epithelial cells. Lansoprazole significantly inhibits the production of CINC-1 from stimulated RGM-1 cells with IL-1β. Lansoprazole up-regulates HO-1 expression throughout Nrf2 in rat gastric epithelial cells, and the up-regulated HO-1 has anti-inflammatory effects. [2]
In vivo Lansoprazole inhibits acute inflammatory reactions as well as intestinal mucosal injuries induced by ischemia-reperfusion or indomethacin administration in rats. Lansoprazole significantly inhibits intestinal injuries induced by ischemia-reperfusion or indomethacin. lansoprazole administered exogenously prevents the small intestine against ischemia-reperfusion or indomethacin-induced damage, the action being dependent on its anti-inflammatory and anti-oxidative responses.
