生物活性 | BMS-202 is a potent and nonpeptidicPD-1/PD-L1complexinhibitor with anIC50of 18 nM and aKDof 8 μM. BMS-202 binds toPD-L1and blocks humanPD-1/PD-L1interaction. BMS-202 has antitumor activity[1][2]. |
IC50& Target | IC50: 18 nM (PD-1/PD-L1)[1] KD: 8 μM (PD-1/PD-L1)[1] |
体外研究 (In Vitro) | BMS-202 (0-100 μM; 4 days; SCC-3 or Jurkat cells) treatment inhibits the proliferation of strongly PD-L1-positive SCC-3 cells (IC50of 15 μM) and anti-CD3 antibody-activated Jurkat cells (IC5010 μM) in vitro[2]. BMS-202 selectively induces thermal stabilization of PD-L1. BMS-202 induces dimerization of PD-L1 in solution.BMS-202 is located at the center of the homodimer filling a deep hydrophobic pocket contributing multiple additional interactions between the monomers. BMS-202 interacts with both PD-L1 molecules using hydrophobic surfaces physiologically involved in the PD-1/PD-L1 interaction[1].
Cell Proliferation Assay[2] Cell Line: | SCC-3 or Jurkat cells | Concentration: | 0-100 μM | Incubation Time: | 4 days | Result: | Inhibited the proliferation of strongly PD-L1-positive SCC-3 cells (IC50of 15 μM) and anti-CD3 antibody-activated Jurkat cells (IC5010 μM) in vitro. |
