PCI-24781 (Abexinostat) is a broad-spectrum phenyl hydroxamic acid HDAC inhibitor currently being evaluated in phase I clinical trials in patients with neoplastic disease. The substance is a specific inhibitor of multiple HDAC isoforms (HDAC2, HDAC3/SMRT, HDAC6, HDAC8, HDAC10) that potently inhibits tumor growth in vivo with acceptable toxicity.
