SR9009. Investigational name: SR9009

SR9009 profile:

Physiological processes involving metabolism and behaviour, e.g., activity/rest, are generally organised on a cycle of approximately 24 hours driven by a circadian rhythm.1 Disruption in circadian behaviours, particularly sleep, is associated with negative health outcomes. Insufficient sleep contributes to obesity, diabetes, cardiovascular disease, and decreased alertness and memory.1,2 In a recent study, patients exposed to one week of insufficient sleep (5.7 ±0.03 h) revealed up and down regulated genes, including those involved in the circadian rhythm, sleep homeostasis, oxidative stress and metabolism, which highlights the crosstalk between sleep and metabolism.2

The nuclear receptors reversed-viral erythroblastosis α and β (REV-ERB α and β) regulate the expression of core clock proteins and therefore modulate the circadian rhythm.1 Like most nuclear receptors, the REV-ERBs are ligand-dependent transcription factors and considerable progress has been made identifying both endogenous and synthetic ligands specific for these NRs.3 The number of compounds that have been developed to target components of the circadian molecular clock is very limited and of those there is even less data available demonstrating a clear therapeutic value for these types of compounds at this point.4 SR9009 is a Rev-ErbA ligand, developed by Prof. Thomas Burris of the Scripps Research Institute.

Recently, the REV-ERBα and REV-ERBβ (NR1D1 and NR1D2, respectively) have received considerable attention due to their integral roles in regulation of the core clock proteins. In fact, REV-ERBs have been proposed as core clock proteins since mice lacking both REV-ERBα and REV-ERBβ lack a circadian rhythm.4

To investigate the usefulness of REV-ERB agonists to affect sleep characteristics, SR9009 was administered in several experiments to test short-term tolerance, efficacy, and optimal time points in which it would remain effective.4 Results from these studies suggested that REV-ERB agonists may be useful in aiding the maintenance of wakefulness in pathological conditions affecting sleep.1,2,4

SR9009 in particular, was able to induce wakefulness at different times during the light period and showed no short-term tolerance development while maintaining its efficacy when administered repeatedly throughout the rodent’s inactive period.4 When SR9009 was administered at the time of peak REV-ERB mRNA expression, increased wakefulness for the first 2-3hrs immediately after injection was observed in several EEG studies in mice. Recent experiments have also demonstrated that REV-ERB agonists not only induce wakefulness and reduce sleep, but the compounds are also effective as anxiolytic agents.4

Modulation of the REV-ERB activity by synthetic agonists, like SR9009 also alters the expression of genes involved in lipid and glucose metabolism and, therefore, plays an important role in maintaining the energy homeostasis.1 Effects of SR9009 observed via in vitro and in vivo animal studies include increased basal oxygen consumption; decreased cholesterol and bile acid synthesis in the liver, and reduced lipogenesis; increased mitochondrial content, glucose and fatty acid oxidation in the skeletal muscle as well as decreased lipid storage in the white adipose.1 The recorded increase in energy expenditure and decrease in fat mass make the REV-ERB agonist SR9009 a promising candidate for the treatment of numerous metabolic disorders. Moreover, the increase in exercise capacity observed via in vivo animal studies makes it attractive for performance enhancement.1

REV-ERBs have been demonstrated to play important roles in regulation of immune function as well; these receptors have been shown to regulate the expression of inflammatory cytokines interleukin-6 and Ccl2; REVERBα is expressed in macrophages found in human atherosclerotic lesions.3 A recent study demonstrates that hematopoetic knock down of REV-ERBα can increase atherosclerosis in LDLR null mice providing clear evidence that REV-ERB plays a role in atherosclerosis.5 Furthermore, use of SR9009 in atherosclerotic mice resulted in gain of REV-ERB function and reduced atherosclerosis. Also, when mice were treated with SR9009 twice a day, significant effects on plasma lipid levels were observed.3 Such findings suggest that REV-ERBα has anti-atherogenic function and may represent a novel target for prevention and treatment of atherosclerosis.3
