Figure 10. Photosensitizers that are ABC transporter substrates are resistant to PDT. Cell viability assays were performed 24 h post-PDT for (A) BPD, (B) Methylene Blue, (C) Redaporfin, and (D) Rose Bengal; (E) The IC50 (reported in μM) for each photosensitizer for the respective cell line is summarized in the table. ABC: ATP binding cassette; PDT: photodynamic therapy; BPD: benzoporphyrin derivative.
