bmspep-57

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).

BMSpep-57 hydrochloride, a potent macrocyclic peptide, competitively inhibits PD-1/PD-L1 interaction, exhibiting an IC50 value of 7.68 nM. It binds to PD-L1 with dissociation constants (Kds) of 19 nM and 19.88 nM as determined by MST and SPR assays, respectively. This compound enhances T cell functionality by promoting IL-2 production in PBMCs[1].
