      Ibuprofen (Motrin) is an anti-inflammatory inhibitor targeting COX-1 and COX-2, of which is used for pain relief, fever reduction and for reducing swelling.;Target: COX-1; COX-2 ;Ibuprofen (INN) is a nonsteroidal anti-inflammatory drug (NSAID) used for pain relief, fever reduction, and for reducing swelling.Nonsteroidal anti-inflammatory drugs such as ibuprofen work by inhibiting the enzyme cyclooxygenase (COX), which converts arachidonic acid to prostaglandin H2 (PGH2). PGH2, in turn, is converted by other enzymes to several other prostaglandins (which are mediators of pain, inflammation, and fever) and to thromboxane A2 (which stimulates platelet aggregation, leading to the formation of blood clots).Like aspirin and indomethacin, ibuprofen is a nonselective COX inhibitor, in that it inhibits two isoforms of cyclooxygenase, COX-1 and COX-2. The analgesic, antipyretic, and anti-inflammatory activity of NSAIDs appears to operate mainly through inhibition of COX-2, whereas inhibiti MedChem Express HY-78131
