Abstract

Histone Deacetylases (HDACs) enzymes are critical in regulating gene expression and transcription. They also play a fundamental role in regulating cellular activities such as cell proliferation, survival and differentiation. Inhibition of HDACs has generated many fascinating results including a new strategy in human cancer therapy. HDAC Inhibitors (HDACIs) like SAHA, TSA are emerging as new promising drugs for various anti-inflammatory and CNS-disorders. This review, along with chemical classification, emphasizes on the therapeutic potential of various HDACIs against different diseases.
