order to take advantage of both immunotherapeutic and epigenetic antitumor agents, the first generation of dual indoleamine 2,3-dioxygenase 1 (IDO1) and histone deacetylase (HDAC) inhibitors were designed. The highly active dual inhibitor 10 showed excellent and balanced activity against both IDO1 (IC50 = 69.0 nM) and HDAC1 (IC50 = 66.5 nM), whose dual targeting mechanisms were validated in cancer cells
