PROTAC PD-L1 degrader-2

Description

PROTAC PD-L1 degrader-2 Compound 9i is a PROTAC degrader for PD-L1, that inhibits PD-L1 with an IC50 of 197.4 nM and exhibits an affinity with PD-L1 with a Kd of 301 nM. PROTAC PD-L1 degrader-2 promotes the internalization of PD-L1 on the cell membrane, and induces PD-L1 degradation via the synergistic effect of the proteasome and lysosomal pathways. PROTAC PD-L1 degrader-2 can activate the immune system, and exhibits antitumor efficacy in MC38 C57BL/6 mouse model.
