Table 3 Determination of relative cell viability (IC50 values) of cancer cell lines (colorectal cancer (DLD-1, HT-29, HCT-116), prostate cancer (PC-3) and pancreatic cancer (BxPC-3)) or normal cells: normal human colon tissue cells (CCD 841 CoN), human lung fibroblasts (WI-38 cells) and peripheral blood lymphocytes (PBLs), treated with MM124 and MM125 using 72-h MTT assay. The values were provided with standard deviation (± SD) [µM]. Additionally, median IC50 values obtained for MM-compounds in cancer and normal cells were summarized to calculate the selectivity index (SI) (ratio of median IC50 values in normal cell lines and cancer cell lines).
