NCIt definition : An orally bioavailable benzamide and inhibitor of human class I histone deacetylases
(HDACs) isoenzymes 1, 2 and 3, with potential antineoplastic activity. Domatinostat
selectively binds to and inhibits class I HDACs leading to an accumulation of highly
acetylated histones. This may result in an induction of chromatin remodeling, the
selective transcription of tumor suppressor genes, and the tumor suppressor protein-mediated
inhibition of tumor cell division and eventually the induction of tumor cell apoptosis.
This may inhibit tumor cell proliferation in susceptible tumor cells. HDACs, upregulated
in many tumor types, are a class of enzymes that deacetylate chromatin histone proteins.;
