Mechanism Of Action and Pharmacodynamic Effects Click here for help
Romidepsin is thought to be a prodrug which releases a zinc-binding thiol upon intracellular reduction. It is this thiol which interacts with the zinc atom in the binding pocket of the histone deacetylase, an interaction which blocks histone deacetylase activity and ultimately induces cell cycle arrest and apoptosis of cancer cells.
