pd-l1/pd-1

BMS-1 (PD-1/PD-L1 inhibitor 1) is an inhibitor of the PD1-PD-L1 protein-protein interaction. It also acts as an immunomodulator.

High tumor expression of PD-L1 was associated with increased tumor aggressiveness and a 4.5-fold increased risk of death.

Pembrolizumab (MK-3475) is a highly selective humanized monoclonal antibody that antagonizes PD-1. It can block the PD-1 protein on T cells and prevent their interaction with PD-L1 on cancer cells.

BMS-202 (PD1-PDL1 inhibitor 2) is a non-peptide PD-1/PD-L complex inhibitor with an IC50 of 18 nM and a KD of 8 μM. BMS-202 binds to PD-L1 with high affinity and blocks human PD-1/PD-L interactions, exhibiting antitumor activity.

D18 is an immune modulator that acts as a dual agonist for TLR7/8 (with EC50 values of 24 nM for hTLR7 and 10 nM for hTLR8, respectively). It enhances the expression of PD-L1 through epigenetic regulation, thereby increasing the sensitivity of tumors to PD-1/PD-L1 blockade. Additionally, D18 functions as a cytotoxin for ADC synthesis, specifically for the ADC HE-S2 [1].
