| Hazard Information | Back Directory | [Description]
EX-527 (49843-98-3) is a selective SIRT1 inhibitor (IC50=98 nM). Does not inhibit other HDACs or SIRT family members. Increases p53 acetylation following DNA damage. Cell permeable. | [Uses]
A selective inhibitor of SIRT1 over SIRT2 and SIRT3 | [Definition]
ChEBI: 6-chloro-2,3,4,9-tetrahydro-1H-carbazole-1-carboxamide is a member of the class of carbazoles that is 2,3,4,9-tetrahydro-1H-carbazole which is substituted at position 1 by an aminocarbohyl group and at position 6 by a chlorine. It is a member of carbazoles, a monocarboxylic acid amide and an organochlorine compound. | [General Description]
A cell-permeable indole compound that acts as a potent and highly selective inhibitor of SIRT1 (IC50 = 98 nM). It inhibits other sirtuin family deacetylases only at much higher concentrations (IC50 = 19.6 and 48.7 μM for SIRT2 and SIRT3, respectively) and shows no inhibitory effect against class I and II HDACs or NAD glycohydrolase even at concentrations as high as 100 μM. Shown to be orally bioavailable with a serum half-life of 136 minutes in mice in vivo. | [Biological Activity]
Selective inhibitor of SIRT1 that does not inhibit histone deacetylase (HDAC) or other sirtuin deacetylase family members (IC 50 values are 98, 19600, 48700, > 100000 and > 100000 nM for SIRT1, SIRT2, SIRT3, HDAC and NADase respectively). Enhances p53 acetylation in response to DNA damaging agents. | [Biochem/physiol Actions]
Primary TargetSIRT1 | [Synthesis]
Step 3: Ethyl 6-chloro-2,3,4,9-tetrahydro-1H-carbazole-1-carboxylate (1 g, 3.60 mmol, 1.00 eq.) was added to a 30 mL high-pressure reactor with a methanol solution of NH3 (7 M, 15 mL). The reactor was sealed and the reaction was stirred at 100 °C for 15 hours. Upon completion of the reaction, the reaction mixture was concentrated under reduced pressure to remove the solvent. The crude product was purified by preparative high performance liquid chromatography (HPLC) under the following conditions: the column was a Bridge Shield RP18 OBD column (5 μm, 19×150 mm); the mobile phases were water (containing 0.05% trifluoroacetic acid) and acetonitrile (acetonitrile ratio was increased from 31.0% to 42.0% in 10 min); the detection wavelength was UV 254/ 220 nm.The final product was 6-chloro-2,3,4,9-tetrahydro-1H-carbazole-1-carboxamide 400 mg (45% yield) as a white solid. The structure of the product was confirmed by NMR hydrogen spectroscopy (400 MHz, DMSO-d6): δ 10.81 (s, 1H), 7.44-7.36 (m, 2H), 7.29 (m, 1H), 7.10 (s, 1H), 7.00 (m, 1H), 3.66 (m, 1H), 2.64-2.56 (m, 2H), 2.11-1.89 (m , 3H), 1.70 (m, 1H). Liquid chromatography-mass spectrometry (LC-MS) analysis showed m/z = 249 [M + H]+. | [storage]
