5.6 Biological Half-Life

Approximately 3 hours


5.7 Mechanism of Action

Romidepsin is a prodrug, where it becomes active once taken up into the cell. The active metabolite has a free thiol group, which interacts with zinc ions in the active site of class 1 and 2 HDAC enzymes, resulting in inhibition of its enzymatic activity. Certain tumors have over expressed HDACs and downregulated/mutated histone acetyltransferases. This imbalance of HDAC relative to histone acetyltransferase can lead to a decrease in regulatory genes, ensuing tumorigenesis. Inhibition of HDAC may restore normal gene expression in cancer cells and result in cell cycle arrest and apoptosis.
