Full Information of The Activity Data of The ADC(s) Related to This Linker
38283215 ADC 20 [Investigative]
Revealed Based on the Cell Line Data
| Experiment 1 Reporting the Activity Date of This ADC | [1] | ||||
| Efficacy Data | Half Maximal Effective Concentration (EC50) |
0.48 ug/mL
|
High TNF expression (TNF +++) | ||
| Method Description |
ADC1-ADC27 with a DAR value of ~4 were screened in a GRE luciferase reporter assay in K562 cells over expressing mTNF and wild-type K562 cells to assess potency resulting from targeted delivery vs. nonspecific uptake. All the ADCs were inactive in the wild-type cells, suggesting the activity seen in mTNF over expressed cells was through targeted ADC uptake followed by intracellular release of compound C1.

| Experiment 2 Reporting the Activity Date of This ADC | [1] | ||||
| Efficacy Data | Half Maximal Effective Concentration (EC50) | > 26 ug/mL | Negative TNF expression (TNF-) | ||
| Method Description |
