Published in 2022 at "ChemMedChem"

DOI: 10.1002/cmdc.202200583

Abstract: Fenoprofen is a widely used nonsteroidal anti‐inflammatory drug (NSAID) against rheumatoid arthritis, degenerative joint disease, ankylosing spondylitis and gout. Like other NSAIDs, fenoprofen inhibits the synthesis of prostaglandins by blocking both cyclooxygenase (COX) isoforms, COX‐1… read more here.
