Abstract
In this study, 15 new 3(2H)-pyridazinone derivatives carrying N'-(4-substitutedphenylmethylidene)acetohydrazide moiety on lactam nitrogen were synthesized and their chemical structures were confirmed by 1H-NMR, mass, and elemental analysis. Analgesic and anti-inflammatory activities of the synthesized compounds were evaluated in mice. Among the synthesized compounds, compound 11e exhibited the best analgesic and anti-inflammatory activities, without causing any gastric effect in stomachs of tested animals. Additionally, the synthesized compounds were screened for their antibacterial and antifungal activities against some pathogenic strains.
Keywords: 3(2H)-Pyridazinone, Acetohydrazide, Analgesic activity, Anti-inflammatory activity, Antibacterial activity, Antifungal activity.
