Effects of aceclofenac and its metabolite, 4′-hydroxyaceclofenac on prostaglandin E2 (PGE2) production by rheumatoid synovial cells were studies. First-passage synovial cells (106 cells/ml) from 10 patients with rheumatoid arthritis were cultured in the presence of aceclofenac and 4′-hydroxyaceclofenac in range of concentration: 0.0001 – 100 uM. After 24 h in culture, amount of PGE2 in culture medium was measured by enzyme immunoassay. It was found, that diclofenac and 4′-hydroxydiclofenac suppressed PGE2 production, with IC50 values of 1.3 ± 0.6 nM (n = 10) and 16.9 ± 8.5 nM (n= 9), respectively.
