Fig. 7. IC50 values after treatment with different preparations of echinomycin. (A) The dose–response curve for U-87 MG cells treated with free echinomycin. (B) The dose–response curve for U-87 MG cells treated with echinomycin-in-γCD inclusion complexes. (C) The dose–response curve for U-87 MG cells treated with echinomycin-in-γCD-in-liposomes. (D) Confocal imaging microscopy treated with rhodamine labeled showing the localization of liposomes in the cytoplasm. All cytotoxicity values represent the average ± SD of three independent experiments.
