Mocetinostat is a rationally designed, orally available, Class 1-selective, small molecule, 2-aminobenzamide HDAC inhibitor with potential antineoplastic activity. Mocetinostat binds to and inhibits Class 1 isoforms of HDAC, specifically HDAC 1, 2 and 3, which may result in epigenetic changes in tumor cells and so tumor cell death; although the exact mechanism has yet to be defined, tumor cell death may occur through the induction of apoptosis, differentiation, cell cycle arrest, inhibition of DNA repair, upregulation of tumor suppressors, down regulation of growth factors, oxidative stress, and autophagy, among others. Overexpression of Class I HDACs 1, 2 and 3 has been found in many tumors and has been correlated with a poor prognosis.

4 Pharmacology and Biochemistry
4.1 Pharmacology

All HDAC inhibitors induce histone H3 hyperacetylation, correlating with inhibition of proliferation, induction of cell differentiation and apoptosis.


4.2 MeSH Pharmacological Classification

Histone Deacetylase Inhibitors

Compounds that inhibit HISTONE DEACETYLASES. This class of drugs may influence gene expression by increasing the level of acetylated HISTONES in specific CHROMATIN domains. (See all compounds classified as Histone Deacetylase Inhibitors.)


4.3 Mechanism of Action

Mocetinostat is a novel isotypic-selective inhibitor of the enzyme histone deacetylase (HDAC). HDAC inhibitors act by turning on tumour suppressor genes that have been inappropriately turned off. Tumour suppressor genes are a natural defense against cancer. It is therefore hypothesized that specifically inhibiting those HDACs involved in cancer with Mocetinostat may restore normal cell function and reduce or inhibit tumour growth.
