Synthesis and Biological Activity of a New Schiff Base Ligand Pyridazine Based

In this work 3, 6-bis (2-[2-sulfanyl-ethylimino)-methyl]-4-(4-nitro-phenylazo)-3-metoxy-phenol) pyridazine (2) was prepared and its antibacterial properties have studied. the structures of all the newly synthesized compounds have been comfirmed by elemental analysis, ir, 1h-nmr. anti bacterial effects of compounds (1 and 2) have been studied. following concentrations of materials were used: a=0.005 g/ml and b=0.01 m. study was done on two strains of s.aureus and e.coli that experiments were done in trypticase soy broth (tsb) and nutrien agar (tsb; difco laboratory). it is likely that these synthetic materials exert higher antibacterial effect on gram positive bacteria in comparison with gram negative.
