GJ19

GJ19 is a PD-L1 inhibitor with an IC50 of 32.06 nM. It binds effectively to human and mouse PD-L1 proteins, exhibiting KD values of 171 nM and 290 nM, respectively. In a co-culture model of HepG2/hPD-L1 and Jurkat T/hPD-1 cells, GJ19 promotes HepG2 cell death in a concentration-dependent manner. In the B16-F10 melanoma mouse model, GJ19 demonstrates significant tumor growth inhibition. GJ19 is applicable in tumor immunotherapy research.
