[[http://www.uniprot.org/uniprot/HDAC2_HUMAN HDAC2_HUMAN]] Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. Forms transcriptional repressor complexes by associating with MAD, SIN3, YY1 and N-COR. Interacts in the late S-phase of DNA-replication with DNMT1 in the other transcriptional repressor complex composed of DNMT1, DMAP1, PCNA, CAF1. Deacetylates TSHZ3 and regulates its transcriptional repressor activity. Component of a RCOR/GFI/KDM1A/HDAC complex that suppresses, via histone deacetylase (HDAC) recruitment, a number of genes implicated in multilineage blood cell development.<ref>PMID:19343227</ref>

The structure-activity and structure-kinetic relationships of a series of novel and selective ortho-aminoanilide inhibitors of histone deacetylases (HDACs) 1 and 2 are described. Different kinetic and thermodynamic selectivity profiles were obtained by varying the moiety occupying an 11A channel leading to the Zn(2+) catalytic pocket of HDACs 1 and 2, two paralogs with a high degree of structural similarity. The design of these novel inhibitors was informed by two ligand-bound crystal structures of truncated hHDAC2. BRD4884 and BRD7232 possess kinetic selectivity for HDAC1 versus HDAC2. We demonstrate that the binding kinetics of HDAC inhibitors can be tuned for individual isoforms in order to modulate target residence time while retaining functional activity and increased histone H4K12 and H3K9 acetylation in primary mouse neuronal cell culture assays. These chromatin modifiers, with tuned binding kinetic profiles, can be used to define the relation between target engagement requirements and the pharmacodynamic response of HDACs in different disease applications.
