Antibacterial mixture of juglone and silver for combating Staphylococcus aureus

The invention relates to an antibacterial mixture containing juglone (5-hydroxy-1,4-naphthoquinone) and silver nanoparticles, showing synergistic bactericidal activity against Staphylococcus aureus, including antibiotic-resistant strains.

The composition combines two biologically active components – a natural naphthoquinone and a silver ion source in the form of 1–100 nm nanoparticles.

The mixture demonstrates high antibacterial efficacy with significantly reduced concentrations of both components compared to their individual use, confirming a synergistic effect.

The invention can be applied as an antimicrobial agent for external use, particularly for skin and wound infections caused by S. aureus.

Application:

  • Topical preparations for treating skin and wound infections caused by Staphylococcus aureus
  • Sntiseptic and disinfectant agents  in medical and veterinary use,
  • Component of wound dressings and healing-support formulations.
