      Rofecoxib(MK 966) is a potent inhibitor of the COX-2-dependent production of PGE2 in human osteosarcoma cells (IC50= 26?10 nM) and Chinese hamster ovary cells expressing human COX-2 (IC50=18?7 nM).;IC50 value: 26 nM (cell assay);Target: COX2Rofecoxib is a synthetic, nonsteroidal derivative of phenyl-furanone with antiinflammatory, antipyretic and analgesic properties and potential antineoplastic properties. Rofecoxib binds to and inhibits the enzyme cyclooxygenase-2 (COX-2), resulting in an inhibition of the conversion of arachidonic acid to prostaglandins. COX-related metabolic pathways may represent key regulators of cell proliferation and neo-angiogenesis. Some epithelial tumor cell types overexpress pro-angiogenic COX-2. Rofecoxib was used as an anti-inflammatory analgesic which has now been withdrawn from the market because of its association with cardiovascular problems. MedChem Express HY-17372
