Description and Uses

4-hydroxy Tolbutamide is a cytochrome P450 2C8 (CYP2C8) and CYP2C9 metabolite of tolbutamide, a first-generation potassium channel blocker. Tolbutamide 4-hydroxylation is an often used probe reaction in the pharmaceutical industry for the characterization of CYP2C8 and CYP2C9 involvement in the metabolism of clinical drugs.

4-Hydroxytolbutamide has been used as a standard to assay the fungal biotransformation of tolbutamide to 4′-hydroxytolbutamide.
