Vanadium(V) complexes with hydrazides and their spectroscopic and biological properties

Area of Science:

• Inorganic Chemistry
• Medicinal Chemistry
• Biochemistry

Background:

• Oxidative stress is implicated in various diseases.
• Vanadium complexes are known for their diverse biological activities.
• Hydrazide derivatives offer a versatile scaffold for metal complexation.

Purpose of the Study:

• To synthesize novel vanadium(V) complexes with hydrazide ligands.
• To investigate the inhibitory potential of these complexes against oxidative enzymes.
• To assess the radical scavenging activities of the synthesized compounds.

Main Methods:

• Synthesis of vanadium(V) complexes with various hydrazide ligands.
• Characterization using spectral, elemental, and physical data.
• Evaluation of inhibitory activity against xanthine oxidase and lipoxygenase (LOX).
• Determination of non-enzymatic radical scavenging activities (DPPH, nitric oxide, superoxide).

Main Results:

• Vanadium(V) complexes exhibited octahedral geometry.
• Both ligands and complexes demonstrated DPPH radical scavenging potential.
• Vanadium(V) complexes showed significant inhibitory activity against lipoxygenase (LOX).
• Complexes displayed varying degrees of activity against nitric oxide, superoxide, and xanthine oxidase, unlike the uncoordinated ligands.

Conclusions:

• The synthesized vanadium(V) hydrazide complexes possess notable antioxidant and enzyme inhibitory properties.
• The structural features, including geometry and substituent groups, significantly influence the biological activity.
• These findings highlight the therapeutic potential of vanadium(V) complexes in managing oxidative stress-related conditions.
