title: 3-O-substituted benzyl pyridazinone derivatives as COX inhibitors.
abstract: New 3-O-substituted benzyl pyridazinone compounds have been synthesised and evaluated for their cyclooxygenase inhibitory activity and COX-2 selectivity. Among the compounds synthesised, three compounds (11b-11d) have shown in vitro COX-2 selectivity. These compounds have been evaluated for their in vivo potential using carrageenan-induced rat paw edema assay. One compound (11b) showed 32% anti-inflammatory activity at 30 mgkg(-1) dose.
