HumanPD-L1inhibitor I is a peptide ligand that specifically inhibits the interaction between humanPD-L1 and humanPD-1. It exhibits a KD value of 3.39 μM, indicating its binding affinity. The presence of HumanPD-L1inhibitor I disrupts the binding between humanPD-L1 and humanPD-1, thereby attenuating their respective functions.
HumanPD-L1inhibitor IV is a polypeptide compound that competitively inhibits the humanPD-1 protein. It has a Kd value of 1.38 μM and effectively blocks the interaction between hPD-1 and hPD-L1.
