Cyclooxygenase 3 Inhibition: A Probable Mechanism of Acetaminophen in Human: A Review
Abstract: The key rate-limiting step in prostanoid and thromboxane biosynthesis is catalyzed by Cyclooxygenases (COXs) and is the target of nonsteroidal anti-inflammatory drugs (NSAIDs). Until recently, the existence of only two isoforms: COX-1 and COX-2; remained under debate as the anti-pyretic and analgesic property of acetaminophen (paracetamol) could not be explained by mere COX-1 or COX-2 blockades. A novel COX-1 splice variant termed COX-3, sensitive to acetaminophen, was recently discovered in …
