Dissociation constants (Kd) of complexes formed with Abl1 kinase.

Compound K d a [nM]
Nilotinib (1) 3.9 ± 0.3
Nilotinib-SH (1a) 881 ± 151
Ponatinib (2) 0.9 ± 0.5
Ponatinib-SH (2a) 0.6 ± 0.1
Ponatinib-BT (2b) 8.4 ± 2.3

The determination of the dissociation constants (Kd) was performed with non-phosphorylated Abl1 kinase using the KdELECT assay (DiscoverX). The Kd values were calculated from quadruplicates.
