Ufiprazole Chemical Properties,Usage,Production

Synthesis

Ufiprazole can be synthesized by the condensation reaction of 2-mercapto-5-methoxybenzimidazole and 2-chloromethyl-4-methoxy-3,5-lutidine.

Description

Omeprazole sulfide is an intermediate used in the production of the gastric proton pump inhibitors, omeprazole and esomeprazole . As a degradation product, it is reported to be a direct-acting inhibitor of cytochrome P450 2C19 in pooled human liver microsomes (IC₅₀ = 9.7 μM).

Uses

Omeprazole Sulfide (Esomeprazol EP Impurity C(Omeprazole EP Impurity C)) is a metabolite of Omeprazole.

Definition

ChEBI: Omeprazole sulfide is a member of benzimidazoles.

Biological Activity

Ufiprazole (Omeprazole sulfide) is an intermediate in the production of gastric proton pump inhibitors omeprazole and esomeprazole.
