Relevant signaling pathways are identified but off-target effects of the FTO PROTAC degrader QP73 on other m6A modifying proteins and broader profiling outside target family are lacking. A recent paper...

The compound shows a clear time-dependent target degradation. However, selectivity profile has not been performed, so more data is needed despite proof of target engagement. The compound is well-characterised...
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
