Ten novel pyrazole Schiff bases derived from 3-amino-4-cyanopyrazole and aromatic aldehydes, and four metal complexes of Cu(II), Ni(II), Zn(II), and Co(II) have been synthesized and characterized by elemental analysis, IR, 1H NMR, and X-ray analysis. The antibacterial activities have been screened for these compounds against four bacteria: Staphylococcus aureus, Escherichia coli, Bacillus subtilis, and Pseudomonas aeruginosa. The primary biological activity assay showed that all products exhibited medium to high antibacterial activities against Staphylococcus aureus, Escherichia coli and Pseudomonas aerugi-nosa. Cu(II) and Zn(II) complexes had the most intense antibacterial activities against Staphylococcus aureus and Escherichia coli.

Key words: 3-amino-4-cyanopyrazole, metal complex, antibacterial activity, pyrazole Schiff base
