Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal Inhibitory Concentration (IC50)
1.30 nM
High CD276 expression (CD276+++)
Method Description
The in vitro potency of NAMPTi-SMOLs and NAMPTi-ADCs was determined in human tumor cell lines. Cells (2000-4000 cells/well, were incubated at 37°C, 5% CO2 for 24 h and the compounds were added at concentrations of 3x10-12 - 3x10-8 Min triplicates. Cell viability was determined at the beginning (day 0) and after 72-96 h incubation in the presence or absence of NAMPTi-SMOLs or NAMPTi-ADCs.
