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
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
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.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
