The present paper deals with synthesis, characterization and amylase inhibitory activity of pyrazinamide (PYZ) with iron in its both (II) and (III) oxidation states. The synthesized complexes were characterized on the basis of IR, UV, 1H-NMR, 13C-NMR, elemental analysis and SEM. Changes in IR data shows that PYZ form complex with octahedral geometry and binding sites are ring nitrogen and carbonyl group, wherein two sides are satisfied with two chloride ions. SEM images indicate the crystalline state and surface morphology of PYZ and its complexes. Elemental analysis proves the composition of complexes. Pyrazinamide and the complexes showed no significant effect on amylase activity but the activity was inhibited in the presence of ferrous chloride.

KEYWORDS: Pyrazinamide, amylase, ferrous chloride, ferric chloride, oxidation state.
