BMS-8 is a small molecule inhibitor of the protein-protein interaction between programmed death protein 1 (PD-1) and its ligand programmed cell death ligand 1 (PD-L1) with an IC value of 146 nM in a homogeneous time-resolved fluorescence (HTRF) binding assay.
BMS-8 inhibits the PD-1/PD-L1 interaction with IC50 of 7.2 μM. BMS-8, binds directly to PD-L1 and induces formation of PD-L1 homodimers, which in turn prevents the interaction with PD-1.

The binding mode of BMS-8 with one PD-L1 monomer is often more stable than with another PD-L1 monomer, and the small molecules that induce PD-L1 dimerization are further stabilized through non-polar interactions of Ile54, Tyr56, Met115, Ala121, and Tyr123 on the two monomers, as well as the water bridge involved in ALys124.
