PD-1/PD-L1-IN 3 

PD-1/PD-L1-IN 3, a macrocyclic peptide, is a potent and selective inhibitor of the PD-1/PD-L1 and CD80/PD-L1 interactions extracted from patent WO2014151634A1, compound No.1. PD-1/PD-L1-IN 3 interferes with PD-L1 binding to PD-1 and CD80 by binding to PD-L1, with IC₅₀s of 5.60 nM and 7.04 nM, respectively. PD-1/PD-L1-IN 3 can be used for the research of various diseases, including cancer and infectious diseases^[1].

IC50: 5.60 nM (PD-1/PD-L1); 7.04 nM (CD80/PD-L1)^[1]

PD-1/PD-L1-IN 3 (0.1 nM-10 μM) inhibits the binding of PD-1 and CD80 to PD-L1, with IC₅₀s of 5.60 nM and 7.04 nM^[1].
PD-1/PD-L1-IN 3 blocks the binding of recombinant PD-L1-Ig to Jurkat-PD-1 cells, and also block binding of recombinant PD-1-Ig to either L2987 or LK35.2-hPD-L1, with IC₅₀s of 26 nM, 12 nM, and 3.5 nM, respectively^[1].
PD-1/PD-L1-IN 3 (0.001-100 μM) promotes IFN secretion by CMV-specific T cells in a dose-dependent manner, with an EC₅₀ of 400 nM^[1].
