PL120131
PL120131 is a PD-1 antagonist, can specifically blocking the interaction between PD-1 and PD-L1, thereby effectively inhibiting the PD-1-mediated apoptosis signaling pathway. PL120131 rescues lymphocytes from apoptosis, maintains the survival and activity of T cells, and induces cytotoxic T lymphocytes to exert killing effects and recognize macrophages and dendritic cells. PL120131 can be used in research related to breast cancer and various malignant tumors.

Biological Activity
PL120131 (32.0-33.4 μM) rescues Jurkat cells from PD-L1-induced apoptosis, reducing apoptotic signals by 25% with an IC50 of 32.0 μM (Annexin V) and 33.4 μM (Caspase 3/7)[2].
PL120131 (11.6 μM; 24 h) rescues primary mouse T-cells from apoptosis in 4T1 co-cultures, increases 4T1 cell death, and induces a significant, dose-dependent increase in Granzyme B production in CD3+/CD8+ T-cells[2].
PL120131 (0.2-12.5 μg/mL; 24 h) induces dose-dependent increases in IFNγ and dose-dependent decreases in IL-12p70 and IL-10 in co-cultures of primary mouse lymphocytes and 4T1 cells, indicating activated T-cell function[2].
PL120131 (30 μM; 30 min (Jurkat pre-treatment); 24 h (co-culture in microfluidics chip)) enables Jurkat cells to infiltrate a 3D MDA-MB-231 tumor environment, induce greater tumor cell death, and maintain higher Jurkat cell viability than anti-PD-1 antibody treatment[2].
