Biochem/physiol Actions

SAHA or Vorinostat facilitates the transcription of genes that result in apoptosis, differentiation and growth arrest. It has been observed to give beneficial results in lymphoma but not in solid tumors.

Vorinostat or suberoylanilide hydroxamic acid (SAHA) is a potent, reversible pan-histone deacetylase (HDAC) inhibitor. It inhibits both class I and class II HDACs, altering gene transcription and inducing cell cycle arrest and/or apoptosis in a wide variety of transformed cells.
