Recent Study Dual HDAC/PARP Inhibitor for the Treatment of Tumor

The occurrence and development of tumors are closely related to epigenetic instability which modulates gene expression through DNA methylation, histone modification, chromatin remodeling, and RNA-related silencing. Histone deacetylase (HDAC) and poly (ADP-ribose) polymerase WARP) are targets of epigenetic regulation. Over the years, a large number of studies have shown that HDAC inhibitors and PARP inhibitors have synergistic effects in the treatment of tumors, and there are reports of related dual HDAC/PARP inhibitors. This review will give a brief summary of the synergistic mechanisms of HDAC inhibitors and PARP inhibitors and introduce the design of the first dual HDAC/PARP inhibitor, which may guide the design of more dual HDAC/PARP inhibitors for the treatment of tumors.
