N-Acetylimidoquinone BiologicalActivity
| Description | NAPQI is the toxic metabolite of Paracetamol. NAPQI is also an inhibitor of enzymes in the vitamin K cycle. NAPQI is rapidly detoxified by glutathione (GSH), but in situations of GSH deficiency, excess NAPQI reacts with cysteine residues in proteins, causing cell death and toxicity in the liver[1][2]. |
