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.

Identifying drugs that regulate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and its symptoms has been a pressing area of investigation during the coronavirus disease 2019 (COVID-19) pandemic.

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

A novel class of 1-(4-methanesulfonylphenyl and 4-aminosulfonylphenyl)-5-[4-(1-difluoromethyl-1,2-dihydropyrid-2-one)]-3-trifluoromethyl-1H-pyrazole hybrid cyclooxygenase-2 (COX-2)/5-lipoxygenase (5-LOX) inhibitory anti-inflammatory agents was designed. Replacement of the tolyl ring present in celecoxib by the N-difluoromethyl-1,2-dihydropyrid-2-one moiety provided compounds showing dual selective COX-2/5-LOX inhibitory activities. 1-(4-Aminosulfonylphenyl)-5-[4-(1-difluoromethyl-1,2-dihydropyrid-2-one)]-3-trifluoromethyl-1H-pyrazole exhibited good anti-inflammatory

Ibuprofen is used for treatment and prevention of patent ductus arteriosus in low-birthweight infants. Its effects on regional circulations differ from those of indometacin. Because prophylactic indometacin reduces the frequency of severe intraventricular haemorrhage and patent ductus arteriosus, we aimed
