In Vitro Model Invasive breast carcinoma MCF-7 cell CVCL_0031
Experiment 4 Reporting the Activity Data of This PDC [1]
Indication Tumor
Efficacy Data Half Maximal Effective Concentration (EC50)
12.5 μM
Administration Time 15 min
Description
More specifically, compounds 1b and 3b demonstrated significantly higher activity against U87 cells compared to MCF-7 and HT-29 cells (Figure 6). Importantly, 1b was more active than 3b demonstrating that the attached CPP is indeed necessary to increase the overall cellular uptake and thus cytotoxic activity of the conjugates. Of note is also that 2b was less efficient than 1b but marginally more active than 3b, although with no selectivity. For the two conjugates bearing the GFLG motif, it was seen that 3c is still significantly more active in U87 cells expressing integrin receptors. By contrast, 1c kept its selectivity against HT-29 cells, but was pronouncedly more active in MCF-7 cells compared to 1b.
