Antifeedant, Herbicidal and Molluscicidal Activities of Pyridazinone Compounds

The pyridazine moiety is an important and frequent antifeeedant, insecticidal, herbicidal, molluscicidal, plant growth regulatory activity and other agrochemical structural feature of many biologically active compounds. Recently, much attention has been focused on pyridazinone derivatives for their broad-spectrum activities. Substituted pyridazine derivatives were also reported to show antibacterial, antifungal, antiviral, properties. Promoted by the above observations, the combination of two or more heterocyclic and non-heterocyclic systems enhances the biological profile many-fold than its parent nuclei. We considered some compounds bearing pyridazinone in a molecular framework.
