Full List of Activity Data of This Peptide-drug Conjugate
Discovered Using Cell Line-derived Xenograft Model
| Experiment 1 Reporting the Activity Data of This PDC | [1] | ||||
| Indication | Tumor | ||||
| Efficacy Data | Tumer volume |
2400 mm3
|
|||
| Administration Time | Given every other day for a total of five times | ||||
| Administration Dosage | 400 µg/kg (calculated by free DM1) | ||||
| Description |
It was demonstrated here, RCCD@NPs and RSSD@NPs exhibited significantly better tumor-growth inhibition compared with that of the free DM1, QCCD@NPs or QSSD@NPs (Figure (Figure4A).4A). RSSD@NPs showed the most suppression on B16 tumor up to 25 days, and resulted in a tumor volume 4 times smaller than the saline group at the end of the experiment. The final tumor volumes in various nano-DDS groups ranked from the greatest to the least: QCCD@NPs, QSSD@NPs>DM1>RCCD@NPs>RSSD@NPs. Almost the same trends were found in terms of tumor weight and tumor size (Figures (Figures4B,4B, C).

Revealed Based on the Cell Line Data
| Experiment 1 Reporting the Activity Data of This PDC | [1] | ||||
| Indication | Tumor | ||||
| Efficacy Data | Half Maximal Inhibitory Concentration (IC50) |
67.61 ± 13.67 nM
|
|||
| Administration Time | 48 h | ||||
| Description |
The IC50 of QCCD@NPs and QSSD@NPs (389.05±75.25 nM and 245.47±37.54 nM) on B16 cells seemed much higher than the values of RCCD@NPs and RSSD@NPs (102.33±38.92 nM and 21.38±4.32 nM). The cytotoxicity of APDC@NPs on HUVEC showed a similar pattern.
