PROTAC PD-1/PD-L1 degrader-1, a Cereblon E3 ligand-based compound, is a PD-1/PD-L1 PROTAC that effectively inhibits the PD-1/PD-L1 interaction with an IC50 of 39.2 nM. It restores the suppressed immune response in a co-culture model of Hep3B/OS-8/hPD-L1 cells and CD3 T cells and moderately decreases PD-L1 protein levels through a lysosome-dependent mechanism.

| Description | PROTAC PD-1/PD-L1 degrader-1, a Cereblon E3 ligand-based compound, is a PD-1/PD-L1 PROTAC that effectively inhibits the PD-1/PD-L1 interaction with an IC50 of 39.2 nM. It restores the suppressed immune response in a co-culture model of Hep3B/OS-8/hPD-L1 cells and CD3 T cells and moderately decreases PD-L1 protein levels through a lysosome-dependent mechanism. |
| In vitro | PROTAC PD-1/PD-L1 degrader-1 (compound p22) significantly reduces PD-L1 expression on the cell surface by over 14%[1]. When administered at 1-10 μM for 24 hours, it decreases PD-L1 levels dose-dependently, with reductions of 21% and 35% at 1 μM and 10 μM, respectively[1]. Western Blot Analysis in MDA-MB-231 cell lines confirmed its efficacy in modulating PD-L1 expression at these dosages[1]. |
