Novel isoxazoles (10, 12a&b, 15a-c) and the furoxan derivative (14) have been prepared as new safe anti-inflammatoryagents from the hydroximoyl 9. All compounds were evaluated for COX-1\COX-2 and most of them showed promising selectivity. The furoxan derivative 14 gave 59% inhibitory activity using carrageenan induced paw rat edema model.
