A series of novel linear aliphatic amine-linked triaryl derivatives as inhibitors of PD-1/PD-L1 were designed, synthesized, and evaluated in vitro and in vivo. In this chemical series, compound 58 showed the most potent inhibitory activity and binding affinity with hPD-L1, with an IC50 value of 12 nM and a KD value of 16.2 pM, showing a binding potency approximately 2000-fold that of hPD-1. Compound 58 could bind with hPD-L1 on the cellular surface and competitively block the interaction of hPD-1 with hPD-L1. In a T cell funct
