Mocetinostat is a novel small molecule inhibitor specifically targeting histone deacetylase (HDAC) enzymes. It exhibits potent inhibition against a subset of nine human recombinant HDACs, including HDAC1, HDAC2, HDAC3, and HDAC11, while not affecting class II HDACs. Notably, Mocetinostat demonstrates the highest inhibitory activity against human HDAC1 and HDAC2 enzymes in vitro. The inhibitory activity of MGCD0103 reaches a maximum plateau at 6 μM, affecting approximately 75% of the total enzyme activity in HCT116 cells. Extensively studied for its potential in treating certain cancer types, mocetinostat has proven to be a valuable compound in scientific research. Its synthesis method, mechanism of action, biological activity, biochemical and physiological effects, pharmacodynamics, advantages, limitations for lab experiments, and future directions have been investigated. By inhibiting HDAC enzymes, mocetinostat disrupts the removal of acetyl groups from histones, leading to increased histone acetylation and subsequent gene activation. The biochemical and physiological effects of mocetinostat are manifold, encompassing the inhibition of HDAC enzymes, gene activation, suppression of cell proliferation, induction of apoptosis, inhibition of angiogenesis, and mitigation of inflammation. These diverse effects underline the potential of mocetinostat as a versatile tool in both basic and applied research. Understanding its intricate mechanisms and biological outcomes enables further exploration of its therapeutic applications.
