SERP Comments:

This probe is a selective picomolar inhibitor of BCL-XL. I recommend to use this probe to interrogate BCL-XL target in cells. It should be used in combination with ABT-199 (a selective inhibitor of BCL-2) to decouple BCL-XL and BCL-2 pathways. One concern, however, is that the molecule binds BCL-W (K_i=19 nM), and yet it inhibits H146 cells in 10% human serum with EC₅₀=65 nM, which is close to K_i for BCL-W. Thus, BCL-W is a potential off target. As for in vivo use, this probe may be used with caution since its tissue and organ distribution were not reported. It does affect platelet counts (dependence on BCL-XL).
