dPDL1-4
dPDL1-4 is a potent and selective eHSPTAC eHSP90 PD-L1 degrader with DC50s of 7.77 μM and 6.52 μM in HeLa and B16F10 cells. dPDL1-4 bridges eHSP90 with the target protein, inducing lysosomal degradation. dPDL1-4 can degrade PD-L1 significantly and inhibits tumor growth. dPDL1-4 can be used for the study of cervical cancer and melanoma. ((Pink: eHSP90 ligand (HY-174476); Blue: PD-L1 ligand (HY-116274); Black: Linker (HY-W021787); HSP ligand + linker: HY-174799)).
