Use of CercosporinCercosporin is produced by a plant pathogen, Cercosporakikuchii, and the elsinochromes, pigments of the elsinoe family of fungi. 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[1].Cercosporin contains the perylenequinone structural features necessary to PKC activity with an IC50 of 0.6-1.3 μM[2]. |

IC50: 0.6-1.3 μM (PKC)[2] |
| In Vitro | 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)[1]. 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[1]. Cell Viability Assay[1] Cell Line: Human GBM cell lines, T98G and U87; Breast carcinoma cell line, MCF-7 Concentration: 0 μM, 1 μM, 2 μM, 3 μM Incubation Time: 24 hours Result: Exhibited a synergistic cytotoxicity with copper only in the most respiratory cell lines (MCF-7 and T98G). |
