Synthesis and Biological Evaluation of Isonicotinic Acid Hydrazide Conjugated with Diethyelenetriaminepentaacetic Acid for Infection Imaging

Introduction: Isonicotinic acid hydrazide (INH) was coupled to diethylenetriaminepentaacetic acid (DTPA) via amide linkage. Primary object of the present invention was to propose a novel INH derivative based on DTPA, which form stable complexes with most of lanthanides and transition metals in periodic table. Another object of the present invention was to introduce a chelating group in INH with...

Isonicotinic Acid Hydrazide

Synthesis and structural studies of complexes of Cu, Co, Ni and Zn with isonicotinic acid hydrazide and isonicotinic acid (1-naphthylmethylene)hydrazide

Eight new complexes of Cu(II), Co(II), Ni(II) and Zn(II) with isonicotinic acid hydrazide (isoniazid, (INH)) and isonicotinic acid (1-naphthylmethylene)hydrazide (INNMH), having the formula of the type [M(INH)(ac)2] or [M(INNMH)(ac)2] (M = Co(II), Ni(II) and Zn(II)) and [Cu(INH)(ac)2]2, [Cu(INNMH)(ac)2]2, were synthesized and characterized. All complexes were characterized based on elemental an...

Thiazolidin-4-one, azetidin-2-one and 1,3,4-oxadiazole derivatives of isonicotinic acid hydrazide: synthesis and their biological evaluation

A series of thiazolidin-4-one (2a–h; 3a–h), azetidin-2-one (4a–h) and 1,3,4-oxadiazole (5a–h) derivatives of isoninicotinic acid hydrazide (INH) were synthesized in order to obtain new compounds with potential anti-inflammatory, analgesic, ulcerogenic and lipid peroxidation activities. The structures of the new compounds were supported by their IR, 1H-NMR and mass spectral data. All compounds w...

Charge Transfer Interactions between Isonicotinic Acid Hydrazide and Cupric Ions

The interaction of Cu2+ with isonicotinic acid hydrazide (INH) and some of its derivatives has been investigated by means of electron spin resonance, nuclear magnetic resonance, and optical absorption studies. It could be shown that an interaction exists between the metal ions and the hydrazine side chain in addition to the very weak interaction with the ring nitrogen. The results obtained indi...
