Abstract

Acanthamoeba strains were photoirradiated in the presence of light-sensitive organic peroxides (hydroperoxynaphthalimide derivatives) including a Photo-Fenton reagent at 366 nm. The survival rates of Acantharnoeba strains determined after 20 h culture showed a significant decrease only upon photoirradiated conditions. The most effective hydroperoxynaphthalimides among these compounds was the bromohydroperoxynaphthalimide (Br-HPO II). The minimum inhibitory concentration (MIC) of Br-HPO II is 100 times lower than that of hydrogen peroxide.
