Cellular Use Rating
YX968 is a well characterized PROTAC with excellent selectivity for its two targets (HDAC3 and HDAC8), demonstrated with classical Western Blotting techniques as well as unbiased proteomics analysis....

Broader in cell selectivity data and proof of HDAC3 engagement data is needed.

A useful probe for interrogating the effect of combined degradation of HDAC3 and -8. It may be worth considering the degradation of the off-targets NCOR1 and EPHX2.
Note: The Chemical Probes Portal only endorses compounds as chemical probes for use as specific and selective modulators of the proposed target if they receive three or more (3-4) stars. Read more about our evaluation criteria
