OMEPRAZOLE RELATED COMPOUND A (15 MG) (OMEPRAZOLE SULFONE) (AS) Chemical Properties,Uses,Production

Description

Omeprazole sulfone is the major metabolite of the gastric proton pump inhibitor, omeprazole . It is produced by cytochrome P450 (CYP)3A4 sulfoxidation of esomeprazole and is found in plasma. Omeprazole sulfone has been shown to act as a reversible direct-acting and metabolism-dependent inhibitor of CYP2C19 in pooled human liver microsomes (IC₅₀ = 18 μM).

Chemical Properties

Light Yellow Solid

Uses

A metabolite of Omeprazole.

Definition

ChEBI: Omeprazole sulfone is a sulfoxide and a member of benzimidazoles.

in vitro

omeprazole sulfone has been shown to act as a reversible direct-acting and metabolism-dependent inhibitor of cyp2c19 in pooled human liver microsomes with an ic50 of 18 μm [1].

in vivo

three hours after intake of 20 mg omeprazole only, the geometric mean plasma concentration of omeprazole sulfone were 106 nmol/l in 22 samples from subjects known to be extensive cyp2c19 metabolizers (em) and 672 nmol/l in the five subjects known to be poor cyp2c19 metabolizers (pm). the mean log10(omeprazole/omeprazole sulfone) ratio was 0.18 [4].
