Innovative material containing the natural product curcumin, with enhanced antimicrobial properties for active...

Area of Science:

• Coordination Chemistry
• Materials Science
• Microbiology

Background:

• Curcumin, a natural compound, possesses known biological activities.
• Development of novel metal complexes for enhanced therapeutic properties is an active research area.
• Pseudomonas aeruginosa is a significant opportunistic pathogen, often forming biofilms.

Purpose of the Study:

• To synthesize and characterize a new amorphous solid material of a zinc di-iodine curcumin complex.
• To evaluate the antimicrobial activity of the synthesized complex against Pseudomonas aeruginosa.
• To assess the efficacy of the complex incorporated into polystyrene against P. aeruginosa biofilms.

Main Methods:

• Synthesis of the zinc di-iodine curcumin complex [ZnI2(Curc)2] in methanol using triethylamine.
• Characterization using melting point, FT-IR, 1H NMR, and X-ray fluorescence (XRF) spectroscopy.
• Determination of Minimum Inhibitory Concentrations (MIC) and evaluation of antibiofilm activity.

Main Results:

• The amorphous complex [ZnI2(Curc)2] was successfully synthesized and characterized.
• The complex demonstrated significantly higher antimicrobial activity against Pseudomonas aeruginosa (PAO1) compared to free curcumin.
• The new material diffused in polystyrene showed activity against P. aeruginosa biofilms.

Conclusions:

• The synthesized zinc di-iodine curcumin complex possesses notable antimicrobial properties.
• The complex offers improved efficacy over curcumin alone, suggesting potential as an antimicrobial agent.
• The material's antibiofilm activity warrants further investigation for medical and material applications.
