      Valdecoxib (SC 65872) is a COX-2 selective inhibitor with an IC50 value of 5 nM.; IC50 Value: 5 nM (COX-2) [1]; Target: COX-2; Valdecoxib is a non-steroidal anti-inflammatory drug (NSAID) used in the treatment of osteoarthritis, rheumatoid arthritis, and painful menstruation and menstrual symptoms. MedChem Express HY-15762
      Valdecoxib (SC 65872) is a COX-2 selective inhibitor with an IC50 value of 5 nM.;IC50 Value: 5 nM (COX-2) [1];Target: COX-2Valdecoxib is a non-steroidal anti-inflammatory drug (NSAID) used in the treatment of osteoarthritis, rheumatoid arthritis, and painful menstruation and menstrual symptoms. ;In vitro: The overall saturation binding affinity for COX-2 of valdecoxib is 2.6 nM (compared with 1.6 nM for celecoxib, 51 nM for rofecoxib, and 260 nM for etoricoxib), with a slow off-rate (t(1/2) approximately 98 min). Valdecoxib inhibits COX-1 in a competitive fashion only at very high concentrations (IC(50) = 150 microM). Collectively, these data provide a mechanistic basis for the potency and in vitro selectivity of valdecoxib for COX-2. Valdecoxib showed similar activity in the human whole-blood COX assay (COX-2 IC(50) = 0.24 microM; COX-1 IC(50) = 21.9 microM) [1]. The affinity of [(3)H]celecoxib for COX-2 (K(D) = 2.3 nM) was similar to the affinity of [(3)H]valdecoxib (K(D) = 3.2 MedChem Express HY-15762
