ABSTRACT
From the cyclisation of potassium dithiocarbazinate with hydrazine hydrate in water, 4-(amino)-5-phenyl - 4H-1, 2, 4-triazole- 3- thiol belonging to the 1,2,4- triazole derivative have been prepared. The different aromatic aldehydes such as benzaldehyde, 2-hydroxy benzaldehyde, 2,4-dichloro benzaldehyde, 3-methoxy 4-hydroxy benzaldehyde, 4-dimethyl amino benzaldehyde and furfuraldehyde have been attached to the triazole through the Schiff reaction to give different Schiff bases. Ciprofloxacin have been incorporated to the new series of Schiff bases of 1,2,4- triazole via Mannich reaction. The new compounds have been evaluated in vitro for their antimicrobial activity against B.subtilis, K.Pneumoniae, and P.aeruginosa. All the compounds showed in vitro gram positive and gram negative activity generally comparable or superior to that of reference ciprofloxacin.
