IC50: 0.6-1.3 μM (PKC)
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 LD 50 value for the T98G cells (0.14 J cm 2 ) is much less than the LD 50 value for MCF-7 and U87 cell lines (0.26 and 0.24 J cm 2 , 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.
Cell Viability Assay
| Cell Line: | Human GBM cell lines, T98G and U87; Breast carcinoma cell line, MCF-7 |
| Concentration: | 0 μM, 1 μM, 2 μM, 3 μM |
