BMSpep-57

Catalog No. T39106 CAS 1629655-80-6

BMSpep-57, a potent macrocyclic peptide inhibitor, competitively disrupts the PD-1/PD-L1 interaction, demonstrating a significant inhibitory concentration (IC50) of 7.68 nM. It exhibits binding affinity towards PD-L1 with dissociation constants (Kd) of 19 nM and 19.88 nM in MicroScale Thermophoresis (MST) and Surface Plasmon Resonance (SPR) assays, respectively. This compound enhances T cell functionality by promoting Interleukin-2 (IL-2) production within Peripheral Blood Mononuclear Cells (PBMCs).

Description	BMSpep-57, a potent macrocyclic peptide inhibitor, competitively disrupts the PD-1/PD-L1 interaction, demonstrating a significant inhibitory concentration (IC50) of 7.68 nM. It exhibits binding affinity towards PD-L1 with dissociation constants (Kd) of 19 nM and 19.88 nM in MicroScale Thermophoresis (MST) and Surface Plasmon Resonance (SPR) assays, respectively. This compound enhances T cell functionality by promoting Interleukin-2 (IL-2) production within Peripheral Blood Mononuclear Cells (PBMCs).
Targets&IC50	PD-1/PD-L1:7.68 nM (IC50)
In vitro	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 IC 50 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].
