38283215 ADC 27 [Investigative]
Revealed Based on the Cell Line Data
Click To Hide/Show 2 Activity Data Related to This Level
Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal Effective Concentration (EC50)
0.55 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) > 42 ug/mL Negative 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.
