PROTAC IRAK4 degrader-2 (Compound 9) is a PROTAC-based IRAK4 degrader that affords potent IRAK4 degradation with a DC50 in peripheral blood mononuclear cells (PBMCs) cells of 151 nM. PROTAC IRAK4 degrader-2 induce a reduction of IRAK4 protein levels with a DC50 of 36 nM in PBMC cells. PROTAC IRAK4 degrader-2 also leads to the inhibition of multiple cytokines in PBMCs[1].
