CAS: 2923313-69-1

PD-L1/HDAC-IN-1 (Compound 14) is an inhibitor of PD-L1 and HDAC, effectively blocking PD-1/PD-L1 interaction as well as HDAC2 and HDAC3 with IC50 values of 88.10, 27.98, and 14.47 nM, respectively. It exhibits mild cytotoxicity in MCF-7 cells (IC50=19.34 μM) and enhances the expression of PD-L1 and CXCL10, promoting antitumor immune responses by recruiting T cell infiltration into the tumor microenvironment (TME).
