We previously reported that a pan-PAD inhibitor YW3-56 activates p53 target genes to inhibit cancer growth. However, the broad anticancer effi cacy and drug mechanisms of YW3-56 remained largely elusive. Here, gene expression analyses found that ATF4 target genes involved in ER stress response and oxidative stress response were activated by YW3- 56. Depletion of ATF4 greatly attenuated YW3-56 mediated activation of the mTORC1 regulatory genes, SESN2 and DDIT4. Using the ChIP-exo method, high-resolution genomic binding sites of ATF4 and CEBPB were generated prior to and aft er YW3-56 treatment. Moreover, YW3-56 increases cellular ROS levels to facilitate ATF4 target gene activation and cancer cell killing. YW3-56 mediated cell death features mitochondria depletion and autophagy perturbation. At last, YW3-56 treatment eff ectively inhibits the growth of triple negative breast cancer xenograft tumors in nude mice. Taken together, we unveiled the anticancer mechanisms and therapeutic potentials of the pan-PAD inhibitor YW3-56.
