(S)-Lansoprazole Chemical Properties,Uses,Production

Description

(S)-Lansoprazole is a proton pump inhibitor that irreversibly inhibits H⁺/K⁺-stimulated ATPase pumps in parietal cells (IC₅₀ = 5.2 μM), inhibiting gastric acid secretion and increasing intragastric pH. It also inhibits acid formation in isolated canine parietal cells (IC₅₀ = 82 μM). (S)-Lansoprazole is an enantiomerically pure form of lansoprazole . Both (S)- and (R)-lansoprazole are pharmacologically active with similar potencies.

Chemical Properties

Light Brown Solid

Uses

The S-enantiomer of Lansoprazole; a gastric proton pump inhibitor. An antiulcerative.

in vivo

Lansoprazole (20-40 mg/kg) treatment significantly attenuated STZ and HFD -induced memory deficits, biochemical and histopathological alterations^[3].
Lansoprazole (20 mg/kg and 40 mg/kg, p.o.) significantly reduces the STZ and HFD- induced increase in AChE activity^[3].
Lansoprazole (20 mg/kg and 40 mg/kg, p.o.) significantly reduces the STZ and HFD- induced rise in brain MPO level^[3].
Further HFD mice treated with lansoprazole (20 mg/kg and 40 mg/kg, p.o.) shows a marked decrease in the body weight in comparison to the control animals^[3].
