Hazard Information | Back Directory | [Uses]
Potent inhibitor of yeast NAD+-dependent histone deacetylase Sir2p (IC50=60μM). Sensitizes mammalian cells to a variety of DNA-damaging agents by abrogating Sir2p activity on p53. Acts by either altering or blocking access to the acetylated histone binding pocket. | [Definition]
ChEBI: A benzochromenone that is 2,3-dihydro-1H-benzo[f]chromene substituted by an oxo group at position 3. It has been found to exhibit potential inhibitory activity against Sir2 proteins. | [Synthesis Reference(s)]
Journal of the American Chemical Society, 69, p. 2341, 1947 DOI: 10.1021/ja01202a027 | [General Description]
A cell-permeable and selective inhibitor of NAD+-dependent deacetylase activity of Sir2 protein (IC50 = 60 μM). Creates a phenocopy of the sir2 deletion mutant in S. cerevisiae and sensitizes mammalian cells to a variety of DNA-damaging agents by abrogating Sir2p activity on p53. Reported to act by either altering or blocking access to the acetylated histone-binding pocket. | [Biological Activity]
Inhibitor of Sir2p (IC 50 = 60 μ M), an NAD + -dependent Sir2 family deacetylase required for chromatin-dependent silencing in yeast. | [Biochem/physiol Actions]
