TPP-1 TFA
TPP-1 TFA is a potent inhibitor of the PD-1/PD-L1 interaction. TPP-1 TFA binds specifically to PD-L1 with a high affinity (KD=95 nM). TPP-1 TFA inhibits human tumor growth in vivo via reactivating T-cell function.

Biological Activity
TPP-1 TFA binds to PD-L1 with high affinity and blocks PD-1/PD-L1 interaction. The KD value of PD-L1 with TPP-1 TFA peptide is about 95 nmol/L (around five times less than that with PD-1), The binding site of TPP-1 TFA to PD-L1 is close to the interactive site of PD-1 and PD-L1[1].TPP-1 TFA (4 μM) reactivates T-cell functions, it induces IFNγ release significantly higher than control and SPP-1, and the TPP-1 TFA group shows similar outcomes for cell proliferation[1].
