The short version of SR9009 fits in a sentence. The long version — which is the one that helps — is below.
This page was last updated on 2025-11-22 and is reviewed periodically as new material appears.
Because REV-ERB receptors are core clock components, SR9009 has been examined for effects on daily rhythms as well as metabolism. Research has explored whether the compound can shift or reinforce circadian gene expression in tissues such as liver and muscle. Some studies report improved metabolic markers in obese or diabetic mice, while others show context-dependent responses. Questions remain about which effects are direct, which are secondary to timing, and how they might differ across species.
SR9009 is a synthetic small molecule studied as an agonist of REV-ERB nuclear receptors. REV-ERB alpha and REV-ERB beta help regulate circadian rhythms and metabolic gene expression. In laboratory research, SR9009 has been used to probe how these receptors affect skeletal muscle, liver, and adipose tissue. The compound was identified in academic drug-discovery work and is often described in scientific literature by its chemical name and research code. It is not an approved medicine, and human clinical data remain limited or absent.
SR9009 binds REV-ERB receptors and alters their repressive activity on target genes. This action can change transcription of genes involved in lipid handling, glucose metabolism, and mitochondrial function. In rodent studies, treated animals have shown changes in muscle oxidative capacity and exercise performance, though effects vary by dose, duration, and model. The precise molecular steps connecting receptor binding to whole-body outcomes are still an active area of investigation. Findings in animals do not automatically translate to humans.
Identity and purity of SR9009 samples are usually checked with chromatographic and spectrometric methods. High-performance liquid chromatography can separate the compound from related impurities, while mass spectrometry provides molecular mass confirmation. Nuclear magnetic resonance spectroscopy may be used for structural verification in research settings. No single method proves biological activity, and certificates of analysis should be reviewed alongside raw data. Independent testing is often needed because online products vary widely.
SR9009 stability depends on temperature, moisture, light, and solvent. Solid material is generally kept cool and dry, while solutions may require protection from repeated warming and cooling. Degradation can appear as color changes, precipitate, or new chromatographic peaks. Researchers should follow supplier instructions and their own stability data. Long-term storage conditions for human use have not been established because the compound lacks approved clinical formulation.
SR9009 is supplied as a solid research chemical, often in milligram quantities. Laboratories typically weigh it in a controlled environment because fine powders can disperse. Stock solutions are commonly prepared in dimethyl sulfoxide and stored in small aliquots to reduce freeze-thaw cycles. Personal protective equipment and chemical fume hoods are standard when handling unknown or potent compounds. These practices address laboratory safety rather than human use.

Laboratory samples of SR9009 are typically handled as research chemicals rather than pharmaceuticals. Suppliers usually state that the material is for research use only and not for human or veterinary administration. Storage recommendations generally call for a freezer at approximately −20 °C, protection from light, and a desiccated environment. The solid is often described as a white to off-white powder. Solubility is commonly reported in organic solvents such as dimethyl sulfoxide and ethanol, with low solubility in water.
Analytical identification and purity assessment often use high-performance liquid chromatography with ultraviolet detection or mass spectrometry. Liquid chromatography–tandem mass spectrometry is used to detect and quantify SR9009 in biological matrices, including urine and blood, for anti-doping or pharmacokinetic studies. Nuclear magnetic resonance spectroscopy can confirm molecular structure. Stability depends on form and storage: the solid is generally more stable than solutions, and repeated freeze–thaw cycles may degrade samples. Purity is typically reported as a percentage from a certificate of analysis.
SR9009 is a synthetic small molecule that acts on the nuclear receptors REV-ERBα and REV-ERBβ. These receptors are part of the circadian clock machinery and normally repress transcription of certain target genes. In laboratory research, SR9009 is used as a chemical tool to study how REV-ERB activity influences metabolism, inflammation, and daily biological rhythms. The compound is not an approved medicine, and its effects in humans remain largely uncharacterized. It is often described as an investigational agent rather than a therapeutic product.
REV-ERB proteins typically suppress gene expression by recruiting corepressor complexes to DNA response elements. SR9009 binds these receptors and strengthens that repressive action in cell-based assays. Studies in rodents have reported changes in lipid handling, mitochondrial function, and exercise capacity after treatment. Such findings are often cited as evidence for metabolic effects, but species differences and limited pharmacokinetic data make direct translation to humans uncertain. Researchers continue to examine which effects are robust and which depend on specific experimental conditions.
SR9009 is frequently discussed alongside other REV-ERB ligands, including synthetic agonists and natural heme-related molecules. Its selectivity for REV-ERB over related nuclear receptors has been measured in binding and reporter assays, though off-target activity at higher concentrations is possible. The compound is prohibited in sport by the World Anti-Doping Agency, and it is not approved for any medical use in major jurisdictions. Products sold online may be labeled as research chemicals, and their identity and purity are not guaranteed by regulatory review.
Laboratory samples of SR9009 are typically supplied as a white to off-white powder. The compound dissolves readily in organic solvents such as dimethyl sulfoxide and ethanol, while its solubility in water is low. Because of this solubility profile, researchers often prepare concentrated stock solutions in an organic solvent before diluting them into aqueous assay buffers. Light exposure, moisture, and repeated freeze-thaw cycles can degrade many small molecules, so handling procedures usually aim to minimize these factors. Purity is commonly checked before use.
Storage conditions for research-grade SR9009 generally involve a freezer at approximately minus twenty degrees Celsius, sometimes lower for long-term preservation. Containers should remain tightly closed and protected from light. Desiccants may be used to limit moisture uptake. Solutions are often stored in aliquots to avoid repeated warming and cooling. Stability data for the compound under various conditions are limited, so laboratories typically follow supplier recommendations and verify performance through periodic analytical checks rather than assuming indefinite stability.
SR9009 is a synthetic small molecule developed as an agonist of the nuclear receptors REV-ERBα (NR1D1) and REV-ERBβ (NR1D2). These receptors help regulate circadian rhythms and metabolic gene expression. In cell and animal studies, SR9009 alters transcription of genes involved in lipid metabolism, inflammation, and mitochondrial function. It is not an approved medicine, and its pharmacological profile in humans remains largely uncharacterized. The compound is frequently discussed in the context of circadian biology and metabolic research rather than clinical use.
Preclinical reports have linked SR9009 to improved endurance and altered energy expenditure in rodents. Such findings have prompted interest in whether REV-ERB activation can influence skeletal muscle metabolism. However, the reported effects depend on dose, route, and experimental model, and replication across laboratories is limited. Human trials have not established comparable outcomes, so claims about exercise performance remain speculative. The absence of controlled human data is a central limitation in interpreting these observations.
The delegation argued that the annexation was a violation of prior agreements between Moshoeshoe and Wodehouse, while disarmament was unnecessary since the Basuto remained loyal to the Cape. The delegation was not allowed to present its case in the parliament. Petitions from the Basuto and their sympathizers from among the Paris Evangelical Society missionaries followed, all of which failed to produce a favorable result. Letsie I, now old and in declining health, was unwilling to lead an armed revolt, believing it to be futile. Cape Governor Sir Henry Bartle Frere became impatient at the deliberations and ordered Letsie I to enact disarmament immediately, even before the Basuto delegation had returned from Cape Town. Few Basuto complied with the order and handed over their arms. This catalyzed the Cape Parliament to vote in favor of disarmament. The delegation announced their failure to prevent the enactment of the Peace Preservation Act at a pitso convened on 3 July. The heir to the Basuto throne, Lerotholi, spoke against disarmament, while Letsie's brother chief Masopha and his nephew chief Joel Molapo openly challenged the order and advocated for armed resistance. Masopha began to fortify the stronghold of Thaba Bosiu, while the supporters of the rebel chiefs began ignoring orders from the local magistrates. White traders abandoned Basutoland, and Basuto loyalists fled to the magistracies for protection as armed bands roamed freely in the region.
Well-being is a multifaceted topic studied in psychology, especially positive psychology. Biologically, well-being is highly influenced by endogenous molecules that impact happiness and euphoria in organisms, often referred to as "well-being related markers". Related concepts are eudaimonia, happiness, flourishing, quality of life, contentment, and meaningful life.
=== Physical properties of NAPLs === The microscopic properties of NAPLs determine their behavior in the field. If they enter the saturated zone, their density relative to that of water will determine how they behave. As a result, NAPLs are categorized based on their relative density into two primary types: light non-aqueous phase liquids (LNAPLs) and dense non-aqueous phase liquids (DNAPLs). LNAPLs tend to float on the water table, while DNAPLs tend to sink downward and, in some conditions, pool at the bottom. Compared to LNAPLs, DNAPLs are more toxic and less biodegradable. There are a variety of parameters specific to the subsurface environment that are important to consider in quantitative models of NAPL behavior. Some of these parameters include soil permeability, moisture, particle size distribution, capillary force, wettability, and ground water flow velocity. The collection of this data is heterogeneous and complex in nature.
==== 2019: Ankle screw malfunction ==== Complications with McCormick's leg injuries and the resulting surgeries plagued him for years thereafter. During post-injury surgery, a screw was placed into McCormick's ankle as an anchor for a surgical suture to hold a ligament in place. McCormick had initially appeared to recovered from his surgery well; in April 2019, The Oregonian described his injuries as "fully healed" and described McCormick as "fully recovered" prior to Oregon's spring football game on April 20. But less than one month after the spring football game, new swelling and pain arose in McCormick's left ankle. The screw had failed, and had caused another fracture. Doctors, however, had initially misidentified the injury as being a stress fracture arising from overuse, and recommended that McCormick merely rest in order for his ankle to heal. Rest was ineffective at resolving McCormick's pain in the long run; sharp pain resumed after McCormick worked out, and the true cause of the pain—the malfunctioning of the anchor—was not discovered by doctors until shortly before the third game of the 2019 Oregon Ducks football season. McCormick tried to play for part of that third game, hoping to delay surgery until after the football season, but he could not bear the pain—a second left ankle surgery, to replace the anchor, was performed, and his season once again came to an early end.

Inflammation of the esophagus is known as esophagitis. Reflux of gastric acids from the stomach, infection, substances ingested (for example, corrosives), some medications (such as bisphosphonates), and food allergies can all lead to esophagitis. Esophageal candidiasis is an infection of the yeast Candida albicans that may occur when a person is immunocompromised. As of 2021 the causes of some forms of esophagitis, such as eosinophilic esophagitis, are not well-characterized, but may include Th2-mediated atopies or genetic factors. There appear to be correlations between eosinophilic esophagitis, asthma (itself with an eosinophilic component), eczema, and allergic rhinitis, though it is not clear whether these conditions contribute to eosinophilic esophagitis or vice versa, or if they are symptoms of mutual underlying factors. Esophagitis can cause painful swallowing and is usually treated by managing the cause of the esophagitis - such as managing reflux or treating infection.
=== In-source fragmentation === Often, the ionization process is sufficiently violent to leave the resulting ions with sufficient internal energy to fragment within the mass spectrometer. If the product ions persist in their non-equilibrium state for a moderate amount of time before auto-dissociation this process is called metastable fragmentation. Nozzle-skimmer fragmentation refers to the purposeful induction of in-source fragmentation by increasing the nozzle-skimmer potential on usually electrospray based instruments. Although in-source fragmentation allows for fragmentation analysis, it is not technically tandem mass spectrometry unless metastable ions are mass analyzed or selected before auto-dissociation and a second stage of analysis is performed on the resulting fragments. In-source fragmentation can be used in lieu of tandem mass spectrometry through the utilization of enhanced in-source fragmentation annotation (EISA) technology which generates fragmentation that directly matches tandem mass spectrometry data. Fragments observed by EISA have higher signal intensity than traditional fragments which suffer losses in the collision cells of tandem mass spectrometers. EISA enables fragmentation data acquisition on MS1 mass analyzers such as time-of-flight and single quadrupole instruments. In-source fragmentation is often used in addition to tandem mass spectrometry (with post-source fragmentation) to allow for two steps of fragmentation in a pseudo MS3-type of experiment.

SR9009 is a synthetic research compound that acts on REV-ERB nuclear receptors. It is not approved for human use and is sold only as a research chemical. Its effects have been studied mainly in cells and rodents.
It binds REV-ERB alpha and REV-ERB beta and changes the expression of genes tied to metabolism and circadian rhythm. These changes can affect mitochondria and energy use in animal models. The exact chain from receptor binding to physiological outcome is still being mapped.
No reliable human trials show that SR9009 improves athletic performance. Some rodent studies report endurance changes, but these results are not proof of human benefit. Its use in sport is prohibited, and quality and safety data are lacking.
Laboratories commonly use liquid chromatography coupled with mass spectrometry to detect SR9009. The method can identify the compound and estimate concentration in a sample. Detection limits depend on the matrix and instrument.
