Description

Application

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

Biochem/physiol Actions

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.

Potent SIRT1 and SIRT6 inhibitor.
