SR10067, REV-ERB Agonist

Biological Activity:

SR10067 is a potent and specific synthetic REV-ERB agonist that binds to REV-ERB-α with an EC50 ~170 nM and REV-ERB-β with EC50 ~160 nM. Potency of SR10067 was also considerably better in a cotransfection assay using full-length REV-ERBa along with the BMAL1 promoter luciferase reporter (EC50 ~140 nM). It also has good in vivo plasma/brain exposure. Comparing to SR9011 and SR9009, SR10067 has 4-5 folds improvement in potency both in vitro and in vivo. IP administration of SR10067 regulates sleep architecture and emotional behaviour in mice. It induces wakefulness and reduces REM and slow-wave sleep. It can also reduce anxiety-like behaviour. These results indicate that pharmacological targeting of REV-ERB may lead to the development of novel therapeutics to treat sleep disorders and anxiety.

How to Use:

In vitro: SR10067 was used at 5-10 µM concentration in vitro and in cellular assays.
In vivo: IP administration of SR10067 was used at 30 mg/kg to mice.
