NCIt definition : An orally available, small-molecule histone deacetylase (HDAC) inhibitor with potential
antineoplastic activity. Pracinostat inhibits HDACs, which may result in the accumulation
of highly acetylated histones, followed by the induction of chromatin remodeling;
the selective transcription of tumor suppressor genes; the tumor suppressor protein-mediated
inhibition of tumor cell division; and, finally, the induction of tumor cell apoptosis.
This agent may possess improved metabolic, pharmacokinetic and pharmacological properties
compared to other HDAC inhibitors.;
Alternative definition : NCI-GLOSS: A substance being studied in the treatment of several types of cancer.
SB939 blocks the action of an enzyme called histone deacetylase (HDAC) and may stop
tumor cells from dividing. It is a type of HDAC inhibitor.;
