BMSpep-57 hydrochloride
BMSpep-57 hydrochloride is a potent and competitive macrocyclic peptide inhibitor of PD-1/PD-L1 interaction with an IC50 of 7.68 nM. BMSpep-57 hydrochloride binds to PD-L1 with Kds of 19 nM and 19.88 nM in MST and SPR assays, respectively. BMSpep-57 hydrochloride facilitates T cell function by in creasing IL-2 production in PBMCs.

Biological Activity
IC50: 7.68 nM (PD-1/PD-L1 interaction)[1]
In a ELISA competition assay, BMSpep-57 inhibits PD-1/PD-L1 binding up to 98.1% 300 nM. And it shows a concentration dependent inhibition of PD-1/PD-L1 binding with an IC50 of 7.68 nM[1]. BMSpep-57 induced high levels of IL-2 at 1 μM and 500 nM concentrations in SEB-stimulated peripheral blood mononuclear cells[1]. BMSpep-57 (0.2-10 μM; 24 hours) does not show any effect on the Jurkat, CHO and HepG2 cells’ viability at the various concentrations tested[1].
