Paracetamol, 3-monoalkyl- and 3,5-dialkyl derivatives. Comparison of their microsomal cytochrome P-450 dependent oxidation and toxicity in freshly isolated hepatocytes.

Abstract

The effects of 3-monoalkyl- and 3,5-dialkyl-substitution on the cytotoxicity of paracetamol (PAR) in rat hepatocytes was studied. PAR is known to be bioactivated by the hepatic microsomal cytochrome P-450 containing a mixed-function oxidase system presumably to N-acetyl-para-benzoquinone imine (NAPQI), a reactive metabolite which upon overdosage of the drug… (More)
