Synthesis, characterization and pharmacological properties of some 4-arylhydrazono-2-pyrazoline-5-one derivatives obtained from heterocyclic amines

The synthesis of a new series of 4-arylhydrazono-2-pyrazoline-5-ones 7–24 and 22a is described. Structures of the synthesized compounds were confirmed using UV, IR, 1H-NMR, 13C-NMR and EI-mass spectral data. These compounds were tested in vitro against one Gram-positive and two Gram-negative bacteri...
