AR-42, also known as (S)-HDAC-42, is a phenylbutyrate-based histone deacetylase (HDAC) inhibitor. HDACs are enzymes that determine acetylation status of histones, thereby affecting chromatin structure and regulating the expression and activity of numerous proteins involved in both cancer initiation and cancer progression. AR-42 possesses antitumor activity at multiple cellular levels. It is currently in Phase I/Ib trials for hematological malignancies and solid tumors.
