Physical and Chemical Properties | Bioactivity BMS-1 (PD-1/PD-L1 inhibitor 1, PD1-PDL1-IN1) is a PD-1/PD-L1 interacting small molecule compound inhibitor with an IC50 of 6 nM. |
Target | Target Value PD-1/PD-L1 interaction (Cell-free assay) 0.006 μM |
In vitro study | Since PD-1 mediated the exhaustion of natural killer (NK) cell by binding to its ligand PD-L1, BMS-1 (PD-1/PD-L1 inhibitor 1) (1 μM, 3 days) is used to disturb the interaction between PD-1 and PD-L1. Dexamethasone induced increase of PD-1 expression and decrease of cytotoxicity of the co-cultured NK92 cells are reversed by BMS-1. BMS-1, a small-molecule immune checkpoint inhibitor of PD-1/PD-L1, can be used as a therapeutic strategy for tumor immunotherapy. Cell Cytotoxicity Assay Cell Line: NK cells and HepG2 cells Concentration: 1 μM Incubation Time: 3 days Result: Disturbed the interaction between PD-1 and PD-L1. |
In vivo study | BMS-1 (500 μg/mL; 100 μL; i.p.) significantly slows down tumor growth and prolongs the survival rates in BALB/c mice. Animal Model: BALB/c mice Dosage: 500 μg/mL; 100 μL Administration: I.p. Result: Administration significantly slowed down tumor growth and prolonged the survival rates. |
