New Coordination Compounds Based on a Pyrazine Derivative: Design, Characterization, and Biological Study.

Area of Science:

• Coordination Chemistry
• Medicinal Chemistry
• Materials Science

Background:

• The ligand N'-benzylidenepyrazine-2-carbohydrazonamide (L) is biologically active.
• Coordination compounds can exhibit unique biological properties.
• Metal-based drugs are an important class of therapeutics.

Purpose of the Study:

• To synthesize and characterize novel coordination compounds of Mn(II), Fe(III), Co(II), and Ni(II) with ligand L.
• To investigate the in vitro antibacterial, antifungal, and anticancer activities of these compounds.
• To evaluate the potential of these compounds as drug candidates using ADME analysis.

Main Methods:

• Synthesis of coordination compounds.
• Characterization using elemental analysis (EA), thermogravimetric analysis (TG-DTG), infrared spectroscopy (FTIR), and flame-atomic absorption spectrometry (F-AAS).
• In vitro biological screening (antibacterial, antifungal, anticancer) and ADME analysis.

Main Results:

• Successful synthesis and characterization of new metal-ligand complexes.
• Demonstration of significant in vitro antibacterial, antifungal, and anticancer activities for some complexes.
• ADME analysis supported the rational use of these compounds as potential drugs.
• Observed enhanced biological activity in metal complexes compared to the free ligand.

Conclusions:

• The synthesized coordination compounds possess notable biological activities.
• These metal complexes represent promising candidates for further development as antimicrobial and anticancer agents.
• The study validates the potential of these novel compounds in medicinal chemistry applications.
