Hsp70TAC PD-1 Degrader-2 is a PD-L1 Hsp70TAC (Hsp70-targeting Chimeras) degrader with Kd values of 0.36 µM. Hsp70TAC PD-1 Degrader-2 forms a ternary complex with Hsp70 and PD-L1 to drive PD-L1 degradation. Hsp70TAC PD-1 Degrader-2 induces degradation of mature membrane-bound PD-L1 in an Hsp70-dependent manner and via caveolin-mediated endocytosis and lysosomal trafficking. Hsp70TAC PD-1 Degrader-2 accumulates preferentially in tumor cells with elevated Hsp70 expression for tumor-selective PD-L1 degradation. Hsp70TAC PD-1 Degrader-2 can be used for the research of cancer, such as breast invasive carcinoma, glioblastoma multiforme, diffuse large b-cell lymphoma[1]. (Pink: PD-1/PD-L1 ligand (HY-19745A), Blue: Hsp70 ligand (HY-182979), Black: linker (HY-182982)).
