Description:
This is a metabolite of the sulfonamide bacteriostatic antibiotic sulfamethoxazole. Sulfamethoxazole is metabolized via acetylation, catalyzed by liver extramitochondrial N-acetyl transferases. Acetyl-Sulfamethoxazole is excreted in urine. Both compounds can be used as a probe for the molecular percentage enrichement of liver extramitochondrial acetyl-CoA. Acetyl-Sulfamethoxazole can also be used as a reference for sulfamethoxazole impurity and waste determination.
