Farydak ® is a Histone Deacetylase (HDAC) Inhibitor. Histone Deacetylase is an enzyme that is normally present in the cells. In some cancer cells, there is an over expression of HDACs. It is believed that inhibition of the HDAC activity causes cell cycle arrest and cell death. Farydak® works by inhibiting the activity of enzymes, known as histone deacetylases (HDACs). This process may slow the over-development of plasma cells in multiple myeloma patients or cause cancer cells to die. Farydak® shows more cytotoxicity towards tumor cells compared to normal cells. It works best when combined with drugs like bortezomib (Velcade).
