Abstract
Synthesis of new hydrazone derivatives, starting from 2-(3,4-Dichloro-benzoyl)-benzoic acid to 2-(3,4-Dichloro-benzoyl)-benzoic acid ethyl ester than converted into 2-(3,4-Dichloro-benzoyl)-benzoic acid hydrazide with substituted aromatic ketones. The structures of the newly synthesized compounds were confirmed by analytical and spectral analysis of IR, 1H NMR and MASS spectroscopy. The in-vitro antibacterial screening of synthesized compounds was performed against the following standard bacterial strains Escherichia coli (MTCC 1573), and staphylococcus aureus (MTCC 1430). Compound 2-(3,4-dichloro-bezoyl)-benzoic acid [1-(4-bromo-phenyle)-ethyledene]-hydrazide (BP-10), gives the highest activity on Escherichia coli (MTCC 1573) and staphylococcus aureus (MTCC 1430). The in-vitro anthelmintic activity was evaluated on Adult earthworms (Pheretima posthuma). Compound 2-(3,4-dichloro-bezoyl)-benzoic acid (2-oxo-1,2-diphynyl-ethylidene)-hydrazide (BP-7), and 2-(3,4-dichloro-bezoyl)-benzoic acid (2-oxo-1,4-chlorophenyle-ethylidene)-hydrazide (BP-13), gives the highest activity and other is gives the moderate activity against Adult earthworms (Pheretima posthuma).
