Cercosporin is produced by a plant pathogen, Cercosporakikuchii, and the elsinochromes. Cercosporin is a potent photosensitizer with a short activation wavelength. Cercosporin contains the perylene quinone structural features necessary for PKC activity (IC50: 0.6-1.3 μM).

Cercosporin (0-3 μΜ; 24 hours) interplays with copper results in synergistic cytotoxicity in MCF7 and T98G cells, that is, S(CuSO4 + Cerco) ? S(CuSO4) x S(Cerco), barely has an additive effect in U87 cells. Cercosporin (0.8-8.0 μM; 30 s, 60 s, 90 s, 120 s) photodynamic therapy effect is stronger in T98G cells than in U87 or MCF7 cells, the LD50 value for the T98G cells (0.14 J cm2) is much less than the LD50 value for MCF-7 and U87 cell lines (0.26 and 0.24 J cm2, respectively) [1].
