In vitro antiamoebic activity of novel metronidazole derivatives and silver nanoparticle formulations against clinical isolates of Entamoeba histolytica

New laboratory research examining designed metronidazole derivatives and silver nanoparticle formulations as potential anti‑amoebic treatment candidates, promising for further preclinical study.

Key Takeaways
  • Five metronidazole derivatives were designed and synthesized using in silico docking against EhTrxR
  • Silver nanoparticles were green‑synthesized and measured between 29.54 and 53.48 nm in size
  • Combined derivative plus AgNP formulations achieved up to 90% trophozoite mortality at 48 hours
