PD-1-PD-L1

PD-1-IN-18 is a PD1 signaling pathway inhibitor, which acts as an immunomodulator.

PD-1-IN-22 is a potent programmed cell death-1 (PD-1)/programmed cell death-ligand 1 (PD-L1) interaction inhibitor with an IC50 of 92.3 nM.

AUNP-12 (NP-12) is a peptide antagonist of the PD-1 signaling pathway, displays equipotent antagonism toward PD-L1 and PD-L2 in rescue of lymphocyte proliferation and effector functions.
