生物活性:
Cercosporin is produced by a plant pathogen, Pseudocercosporella capsellae. Cercosporin is a potent photosensitizer with a short activation wavelength, mostly suitable for superficial photodynamic therapy (PDT) treatments, especially when it is necessary to avoid perforations.Cercosporin contains the perylenequinone structural features necessary to PKC activity with an IC50 of 0.6-1.3 μM.

体外研究:
Cercosporin (0.8-8.0 μM; 30 s, 60 s, 90 s, 120 s) photodynamic therapy (PDT) 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).Cercosporin (0-3 μΜ; 24 hours) interplays with copper results in a 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.
