A series of 2-substituted-6-(morpholinyl/piperidinyl)pyridazin-3(2H)-ones was synthesized and the structures were established using various spectroscopic techniques. The target compounds were screened for anti-inflammatory and analgesic activities at 20 and 40?mg/kg. The safety of the synthesized derivatives was evaluated by assessing anti-platelet activity and ulcer index. The obtained pharmacological data revealed that 6-morpholinyl derivatives 4a–12a were found to be somewhat more potent than 6-piperidinyl derivatives 4b–6b. The 6-morpholinyl substituted pyridazinone 12a exhibited maximum anti-inflammatory and analgesic activities. Homoveratrylamine substituted compounds 6a and 6b emerged as promising leads in both the series with good anti-inflammatory and analgesic activities without any ulcerogenicity. Anti-platelet activity results of the compounds of both the series showed significantly low bleeding time in comparison with standard drug aspirin indicating the cardiovascular safety of new pyridazinones.

A series of 3-pyridazinones carrying morpholino, arylpiperidino and arylpiperazino moiety in the position 6 IIa-g were synthesized and evaluated for antinociceptive activity. In the modified Koster test in mice 4-(4-fluorophenyl) piperazine, IIf, was found the most active compound. All the compounds except IId were more active than aspirin in the antinociceptive activity test.
