| Efficacy Data | Half Maximal Effective Concentration (EC50) |
56.9 μM
|
|||
| Administration Time | 15 min | ||||
| Description |
More specifically, compounds1band3bdemonstrated significantly higher activity against U87 cells compared to MCF-7 and HT-29 cells (Figure6). Importantly,1bwas more active than3bdemonstrating that the attached CPP is indeed necessary to increase the overall cellular uptake and thus cytotoxic activity of the conjugates. Of note is also that2bwas less efficient than1bbut marginally more active than3b, although with no selectivity. For the two conjugates bearing the GFLG motif, it was seen that3cis still significantly more active in U87 cells expressing integrin receptors. By contrast,1ckept its selectivity against HT-29 cells, but was pronouncedly more active in MCF-7 cells compared to1b.
