PD-L1/HDAC-IN-1

PD-L1/HDAC-IN-1 (Compound 14) is the inhibitor for PD-L1 and HDAC that inhibits PD-1/PD-L1 interaction, HDAC2 and HDAC3 with IC50 of 88.10, 27.98 and 14.47 nM, respectively. PD-L1/HDAC-IN-1 exhibits slight cytotoxicity in MCF-7 (IC50=19.34 μM) . PD-L1/HDAC-IN-1 upregulates the expression of PD-L1 and CXCL10, promoting anti-tumour immune response by recruiting T-cell infiltration into TME[1].
