Biochemical and Toxicity Effects of Some 2-Benzoylpyridine Derivatives on Eobania vermiculata under Laboratory Conditions

Two derivatives of 2-Benzoylpyridine namely; (E)-4-((E)-4-((E)- phenyl(pyridin-2-yl)methyleneamino)benzyl)-N-(phenyl(pyridin-2-yl)methylene)benzenamine (L) and its Cu(II) complex were prepared and screened in vitro on Eobania vermiculata species. The assessment of LC 50 values of screened chemicals after 3 days of treatments was performed via the contact method. A series of four concentrations of the investigated compounds; (50, 150, 250, and 350 ppm) was prepared by using a mixture of distilled water and DMSO (3:1) by volume. The obtained results demonstrated that the tested snails were strongly affected after treatments with the prepared chemical compounds, which reflected the high toxicity of those compounds.
