Splitomicin: A Potent Selective Inhibitor of Silent Information Regulator-2 (Sir2)
Silent Information Regulator-2 (Sir2) is a one of Class III histone deacetylases (HDACs) called Sirtuins. Splitomicin, which is derived from β-naphthol, is a potent selective inhibitor of Sir2. It inhibits nicotinamide adenine dinucleotide+ (NAD+) dependent histone deacetylase activity of Sir2.
