HDAC inhibitor

Weak histone deacetylase (HDAC) inhibitor. Induces differentiation, growth arrest and apoptosis in a number of cell lines. Protects against cerebral ischemic injury and displays neuroprotective effect in a mouse model of Huntington’s disease. Anti-neoplastic agent and transcriptional regulator. Also acts as an inducer of tumor cytostasis and differentiation. Shows chemical chaperone activity.
