Use of N-AcetylimidoquinoneNAPQI 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]. |

Targeting mitochondria with methylene blue protects mice against acetaminophen-induced liver injury.
Hepatology 61(1) , 326-36, (2015) Acetaminophen (APAP) overdose is a frequent cause of drug-induced liver injury and the most frequent cause of acute liver failure in the Western world. Previous studies with mouse models have revealed... |
