Mechanism Of Action and Pharmacodynamic Effects Click here for help
The HDAC inhibitor vorinostat was the first compound designed to inhibit HDACs to be approved for clinical use. HDAC inhibition increases acetylation of histone H3 and leads to downstream activation of the PI3K/Akt and MAPK/Ras signaling pathways and ultimately results in cell cycle arrest and apoptosis [3]. HDAC inhibitors are predicted to have application across a wide range of haematological and solid tumor types.
