SERP Comments:

This ALK PROTAC is unique in being constructed from Alectinib with a phthalimide degrader functionality. The probe inhibits ALK activity in cells and convincingly induces ALK degradation, although with a maximal effect size ca. 70% (ie, signficant ALK remains). High microsomal stability is noted, and IP dosing of rats at 2 mpk or PO dosing of rats at 10 mpk achieves plasma levels expected to target ALK, but no PD markers or evidence of target engagement/degradation in vivo are available. Nonetheless, this is a credible probe that uses a distinct warhead to induce degradation of ALK (including to a lesser extent G1202R mutant ALK).
