Off-Target Selectivity Assesments

Potency assay (off target): The selectivity of KT-253 for MDM2 was investigated using tandem mass tag–based deep proteome profiling of approximately 9,000 human proteins. Treatment of RS4;11 ALL cells with 20 nmol/L KT-253 [10-fold 90% inhibitory concentration (IC90)] for 2, 4, and 8 hours revealed a high level of selectivity. KT-253-mediated degradation of MDM2 promotes stabilization of transcriptionally active p53 and its downstream signaling pathway.
