Off-Target Selectivity Assesments

Probe Selectivity in Vitro:
Selectivity within target family: Profiling against an Invitrogen panel at 10 µM and 1 µM: Strongest inhibition found for NTRK1 (IC50 = 56 nM) and MAP3K9 (IC50 = 75.3 nM). Selectivity outside target family: Cerep profile against 122 human receptors, ion channels, enzymes, and uptake sites: the closest off-target is ADORA3 (Adenosine A3) (Ki = 27 nM); Clean GPCR scan

SERP Comments:

Please keep in mind that other kinases will be inhibited along with FAK. No kinome-wide cellular profiling has been done for this compound, however, based on the biochemical and cell free profiling, one should note that FLT3, CLK2, JAK kinases, TRK kinases will likely be potently inhibited along with FAK. Use caution when interpreting phenotypic results when using defactinib (same with nearly every kinase inhibitor).
