The antibacterial screening of these synthesized compounds was done in dimethyl formamide against four Gram positive bacteria viz.Bacillus cereus, Staphylococcus aureus, Staphylococcus epidermidids and Micrococcus luteus, and three Gram negative bacteria viz. Proteus mirabilis, Escherichia coli and Klebsiella aerogenes. It is observed that in comparison to Schiff bases of 4-amino antipyrine, pyrazole Schiff bases are better for inhibition for these selected Gram positive and Gram negative bacterial strains. 10 04 2016 201 218 http://creativecommons.org/licenses/by/4.0 10.15446/rcciquifa.v45n2.59936 http://www.revistas.unal.edu.co/index.php/rccquifa/article/view/59936 http://www.revistas.unal.edu.co/index.php/rccquifa/article/viewFile/59936/57217 http://www.revistas.unal.edu.co/index.php/rccquifa/article/viewFile/59936/57217
