IC50 values for both complexes were mostly sub-μM towards cancer cells (HT-29, DLD-1, HCT116 (p53 wild type and null), BxPC3, A549 and H460 cell lines) with the exceptions being the pancreatic cancer cell line PSN1 and the GBM1 glioblastoma cancer stem cell model32,33 where IC50 values were >1 μM. Here, TP53 is linked to familial pancreatic carcinoma.
