| | 6-CHLORO-2,3,4,9-TETRAHYDRO-1H-CARBAZOLE-1-CARBOXAMIDE Usage And Synthesis |
| 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 | EX-527 has been used:
- in 1% dimethyl sulfoxide, 30%, polyethylene glycol-400 and 1% Tween 80 for treating C57BL/6 N mice to study its effect on intestinal morphological changes and crypt cell apoptosis
- as a an inhibitor of sirtuin 1, in treating human cancer lines MCF-7 (Michigan cancer foundation-7) and HCT116 (colon cancer cell line) incubated in Dulbecco′s modified Eagle′s medium, to study its effect on mitochondrial ATP (adenosine triphosphate) production
- Intracerebroventricularly infused in rat model of epileptogenesis, to access kainic acid–induced status epilepticus stimulated sirtuin 1 activity
| | Uses | A selective inhibitor of SIRT1 over SIRT2 and SIRT3 | | Uses | EX-527 is a potent and selective sirtuin 1 (SIRT1) inhibitor (IC50 38 nM) identified from a high throughput screen. EX-527 is more selective (200-500-fold) for SIRT1 than for SIRT2 or SIRT3 and has been shown to be a potent SIRT6 inhibitor using H3K56 deacetylation site based substrate. EX-527 does not inhibit class I/II HDAC activity at concentrations up to 100uM. Enhances p53 acetylation in response to DNA damaging agents. EX-527 is racemic; the active isomer (EX-243) gives similar results and potency whereas the other isomer (designated EX-242) is inactive. | | 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 | | storage | Store at +4°C | | References | 1) Napper et al.
