PDL1 degrader-2

PD-L1 degrader-2 (Compound B3) is an orally active AUTAC degrader, that degrades PD-L1 through autophagy-lysosome pathway with a DC50 of 0.5 μM. PD-L1 degrader-2 exhibits inhibitory activity against PD-1/PD-L1 interaction with an IC50 of 22.8 nM. PD-L1 degrader-2 upregulates the expressions of Atg9b, Lamp1 and Mitf, and activates the autophagy lysosome system. PD-L1 degrader- exhibits antitumor efficacy in CT26 mouse model[1].
