Figure 4

Effects of photodynamic therapy (PDT) using the anthracene derivatives Ant-PIm (10 µM, 24 h) and Ant-PHEA (10 µM, 24 h) on the cell survival of CHO-K1 hamster ovary cells, as a function of blue light exposure (0–30 min), as described in “Material and Methods”. The cell viability was measured by MTT assay 24 h post light exposure and was normalized to 100% viability for untreated cells incubated in a drug-free medium. The results were present as mean values ± SD from three separate experiments.
