SERP Comments:

The strong point of the publication revealing TL13-112 is the broad profiling of the PROTAC against many cell lines across range of different time points and concentrations. Also the mechanism of action was relatively well investigated by competition with parent ligands or by co-treatment with neddylation inhibitor or proteasomal inhibitor. The selectivity of degradation has been evaluated using MS-proteomics at 4 h time point, showing a few off-targets (PTK2, FER, Aurora A, ZNF692) but only very weak ALK degradation. It is unclear what would be the selectivity profile under more relevant conditions that would lead to higher ALK depletion. Currently (April 2024) there are better ALK degraders published that could be used as tool compounds.
