SMAC-FRRG-DOX [Investigative]
Discovered Using Cell Line-derived Xenograft Model
| Experiment 1 Reporting the Activity Data of This PDC | [1] | ||||
| Indication | Drug-resistant cancer | ||||
| Efficacy Data | Tumor growth inhibition value (TGI) |
76.00%
|
|||
| Administration Dosage | 1 mg/kg of DOX | ||||
| MOA of PDC |
These results suggest that the DD-NPs could improve the in vivo bioavailability and cancer targeting efficiency of SMAC via their stable nanoparticle-derived EPR effect, leading to effective IAPs inhibition in targeted tumor tissues.
|
||||
| Description |
Finally, the tumor volumes were successfully suppressed from 76% to 89% when the intravenous dose of DD-NPs increased from 1 mg/kg of DOX to 5 mg/kg of DOX.

Revealed Based on the Cell Line Data
| Experiment 1 Reporting the Activity Data of This PDC | [1] | ||||
| Indication | Drug-resistant cancer | ||||
| Efficacy Data | Half maximal inhibitory concentration (IC50) |
7.53 μM
|
|||
| MOA of PDC |
These results suggest that the DD-NPs could improve the in vivo bioavailability and cancer targeting efficiency of SMAC via their stable nanoparticle-derived EPR effect, leading to effective IAPs inhibition in targeted tumor tissues.
|
||||
| Description |
When both cells were treated with different concentrations of DD-NPs (0-186 μg/ml), the cytotoxicity was induced only in MCF-7, showing similar cytotoxicity with free DOX at a high concentration (Fig. 2h). However, DD-NPs did not exhibit significant cytotoxicity in H9C2 whereas free DOX showed similar cytotoxicity when treated to MCF-7 (Fig. 2i).

| Experiment 2 Reporting the Activity Data of This PDC | [1] | ||||
| Indication | Drug-resistant cancer | ||||
| Efficacy Data | Half maximal inhibitory concentration (IC50) |
9.2 μM
|
|||
| Administration Time | 48 h | ||||
| MOA of PDC |
These results suggest that the DD-NPs could improve the in vivo bioavailability and cancer targeting efficiency of SMAC via their stable nanoparticle-derived EPR effect, leading to effective IAPs inhibition in targeted tumor tissues.
|
||||
| Description |
However, DD-NP-treated group showed similar IC50 in wild-MCF-7 (7.53 μM) and ADR-MCF-7 (9.2 μM), due to the synergetic pro-apoptotic effect of SMAC molecules in DD-NPs (Fig. 3g).
