General description

Ibuprofen is a commonly used nonsteroidal anti-inflammatory drug (NSAID) known for its pain-relieving, anti-inflammatory, and fever-reducing properties. It can hinder the effectiveness of various antihypertensive medications, including β-adrenergic blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and diuretics. Ibuprofen exists in an unbound state in cerebrospinal fluid and is accumulated in the synovial fluid of inflamed joints in arthritis patients.

Application

Ibuprofen has been used:
  • to study its vascular and pulmonary effects on neonatal lung development
  • to study its effects on cell apoptosis, cell proliferation, and histology changes in human cholangiocarcinoma cell lines
  • in the preparation of a terpene-based therapeutic deep eutectic system (THEDES) to investigate its physicochemical, antimicrobial, and anticancer properties

Biochem/physiol Actions

Cyclooxygenase (COX) inhibitor that has greater activity against COX-1 than against COX-2.

Every day, hundreds of millions of people worldwide take nonsteroidal anti-inflammatory drugs (NSAIDs), often in conjunction with multiple other medications. In the bloodstream, NSAIDs are mostly bound to serum albumin (SA). We report the crystal structures of equine serum albumin
