Application

6-Hydroxychlorzoxazone has been used for HPLC-based metabolic assays of chlorzoxazone.
6-hydroxy Chlorzoxazone has been used: as a reference standard to monitor substrate depletion or 6-hydroxy chlorzoxazone formation by cytochrome P450 family 2 subfamily E member 1 (CYP2E1)in recombinant human enzyme screening. 6-Hydroxychlorzoxazone has been used for high-performance liquid chromatography (HPLC)-based metabolic assays of chlorzoxazone.
CYP2E1 & 1A2 metabolite of chlorzoxazone.

Biochem/physiol Actions

6-hydroxy Chlorzoxazone is a novel metabolite of chlorzoxazone. It is formed by the hydroxylation of chlorzoxazone by cytochrome P450 family 2 subfamily E member 1 (CYP2E1) enzyme. The determination of formation and clearance of 6-hydroxychlorzoxazone is used as a reliable marker of CYP2E1 metabolic activity.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Preparation Note

6-Hydroxychlorzoxazone is soluble in methanol.

A gas chromatographic-mass spectrometric method is presented which allows the determination of chlorzoxazone and 6-hydroxychlorzoxazone after derivatization with the reagent N-tert.-butyldimethylsilyl-N-methyltrifluoroacetamide. No interference was observed from endogenous compounds following the extraction of plasma samples from six different human subjects. The
