Biological Activity for AUNP 12

AUNP 12 is an immune checkpoint modulator targeting the programmed cell death 1 (PD-1) signaling pathway. It inhibits the interaction between PD-1 and its ligands, PD-L1 and PD-L2. In the mouse splenocyte assay system, AUNP 12 rescues proliferation (EC50 values are 17 and 16 nM for PD-L1 and PD-L2, respectively) and enhances T-cell activity by restoring IFNγ release inhibited by PD-L1 and PD-L2 (EC50 values are 49 nM and 51 nM respectively). In a mouse Renca renal cell carcinoma model, AUNP 12 shows an additive antitumor effect when combined with Cyclophosphamide (Cat. No. 4091).
