Research interest in SR9009 grew from studies showing improved running endurance in mice after short treatment periods. Those experiments linked the compound to increased mitochondrial content and fatty acid oxidation in muscle, but the findings come from animal models and specific dosing schedules. Independent replication has been limited, and the pathways connecting REV-ERB activation to exercise performance are still being mapped. Whether similar responses occur in humans is an open question.
SR9009 is often grouped with compounds studied for circadian and metabolic regulation rather than with classical anabolic steroids. Its interactions with nuclear receptors differ from those of androgen receptor ligands, and its proposed mechanisms involve transcriptional control rather than direct hormone signaling. Some sources classify it as a metabolic modulator because of observed effects on energy utilization. The distinction matters for regulation and for interpreting research results across different compound classes.
Regulatory treatment of SR9009 varies by country and context. It is not approved as a therapeutic drug by agencies such as the United States Food and Drug Administration or the European Medicines Agency. Sports authorities list it as a prohibited substance; the World Anti-Doping Agency classifies it among hormone and metabolic modulators. Legal status for personal possession or sale differs across jurisdictions, and some countries may restrict it under analog or research chemical laws. Buyers who seek verified material often rely on independent laboratory testing because online product labels may not match contents.
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.
| Property | Value | Notes |
|---|---|---|
| Molecular formula | C20H24ClN3O4S | Reported for the free base |
| Molecular weight | 437.9 g/mol | Calculated from the formula |
| Primary target | REV-ERBα and REV-ERBβ | Nuclear receptors involved in circadian regulation |
| Solubility | Soluble in DMSO and ethanol | Poorly soluble in water |
| Typical storage | -20 °C, desiccated | Protect from light and moisture |
Stability depends on physical form, temperature, light exposure, and solvent. Solid SR9009 is generally stored cold and dry, with protection from light to limit degradation. Dimethyl sulfoxide stocks are common for laboratory work, but repeated freeze-thaw cycles can reduce compound integrity. Aqueous solutions may be less stable than organic stocks, and the ethyl ester in the structure can be susceptible to hydrolysis under certain conditions. Researchers typically validate storage conditions and recheck purity before quantitative experiments, especially when using archived material.
Regulatory treatment of SR9009 varies by country and region. It is not approved as a pharmaceutical, and several jurisdictions restrict its sale for human consumption. Some authorities classify it as a research chemical, a prescription-only substance, or a prohibited performance-enhancing agent in sport. Purchasers may encounter certificates of analysis, but these documents do not guarantee identity, purity, or legality. In research settings, institutional safety reviews and controlled procurement help ensure that materials are handled under appropriate oversight. The absence of harmonized rules means that legal status can change and requires verification.
Pharmacokinetic data for SR9009 are limited in published literature. Some reports indicate low oral bioavailability and rapid clearance in animals, which complicates interpretation of exposure and effect. Researchers often use injected routes in preclinical work to achieve measurable systemic levels. Analytical studies rely on mass spectrometry to detect the parent compound and its metabolites. Questions about tissue distribution, active metabolites, and long-term consequences remain open. Species differences in metabolism can affect observed half-life and target engagement.
SR9009 is a synthetic small molecule studied as an agonist of the nuclear receptors REV-ERBα and REV-ERBβ. These receptors help regulate circadian rhythms and metabolic gene expression. In laboratory experiments, SR9009 binds these receptors and alters transcription of genes involved in lipid handling, glucose metabolism, and mitochondrial function. It is not a naturally occurring compound and has no approved therapeutic use. Research interest stems from its ability to modify energy metabolism in cells and animal models.
Regulatory treatment of SR9009 reflects its investigational status. The compound has no approved human therapeutic indication, and sports authorities prohibit its use. It appears on anti-doping lists as a non-approved substance or metabolic modulator, depending on the list version. Products sold online as research chemicals are not quality-controlled medicines, so their identity and purity can differ from the label. Such products may also contain unlisted compounds, which complicates both testing and safety assessment.
Scientific discussion of SR9009 often separates animal evidence from human anecdote. Rodent studies provide controlled data on endurance, metabolism, and gene expression, but they use specific strains, doses, and treatment durations. Human reports are mostly uncontrolled and cannot establish cause and effect. Open questions include oral bioavailability, tissue distribution, metabolic stability, and long-term effects. Review articles generally call for more rigorous pharmacokinetic and safety research before any clinical use could be considered.
Psychologist Bruno Bettelheim believed that autism was linked to early childhood trauma, and his work was highly influential for decades both in the medical and popular spheres. In his discredited theory, he blamed the mothers of individuals with autism for having caused their child's condition through the withholding of affection. Leo Kanner, who first described autism, suggested that parental coldness might contribute to autism. Although Kanner eventually renounced the theory, Bettelheim put an almost exclusive emphasis on it in both his medical and his popular books. Treatments based on these theories failed to help children with autism, and after Bettelheim's death, his reported rates of cure (around 85%) were found to be fraudulent.
As early as 1718 letters from the Secretary at War were addressed from "The War Office". His department had several headquarters in London until it settled at Horse Guards in Whitehall during 1722. It remained there until 1858. Then, following the dissolution of the Board of Ordnance, the War Office moved into the Board's former offices in Cumberland House, Pall Mall. Over the ensuing years it expanded into adjacent properties on Pall Mall before it was relocated to purpose-built accommodation, in what is now known as the Old War Office Building, in 1906. Between 1906 and its abolition in 1964 the War Office was based in a large neo-Baroque building designed by William Young, completed during 1906, and located on Horse Guards Avenue at its junction with Whitehall in central London. The construction of the building required five years to complete, at a cost of more than 1.2 million pounds. The building is somewhat oddly shaped, forming a trapezoid to maximise the use of the irregularly shaped plot of land on which it was built: its four distinctive domes were designed as a decorative means of disguising the shape. It has around 1,100 rooms on seven floors. After 1964 the building continued to be used, under the name The Old War Office, by the Ministry of Defence. On 1 June 2007 the building, other than the steps that give access to it, was designated as a protected site for the purposes of Section 128 of the Serious Organised Crime and Police Act 2005. The effect was to make it a specific criminal offence for a person to trespass on the building.
Other notable mutations identified in ICP patients include ones in the farnesoid X receptor (FXR), a nuclear receptor in hepatocytes which activates transcription of MDR3 and BSEP upon binding intracellular bile acids, thereby increasing canalicular bile efflux.
Moscow is the capital and largest city of Russia, situated on the Moskva River in Central Russia. The city has a population estimated at more than 13 million residents within city limits, more than 19.1 million residents in the urban area, and more than 21.5 million residents in the metropolitan area. The city covers an area of 2,511 square kilometers (970 sq mi); the urban area covers 5,891 square kilometers (2,275 sq mi); and the metropolitan area covers more than 26,000 square kilometers (10,000 sq mi). Moscow is among the world's largest cities: the most populous city entirely in Europe, the largest urban and metropolitan areas in Europe, and the largest city by land area on the European continent. First documented in 1147, Moscow became the capital of the Grand Principality of Moscow, which led the unification of Russian lands in the 15th century and became the center of a unified state. Following the proclamation of the Tsardom of Russia in 1547, Moscow remained the country's political and economic center for most of its history. During the reign of Peter the Great, the Russian capital was moved to the newly founded city of Saint Petersburg in 1712, leading to a decline in Moscow's importance throughout the imperial period. Following the Russian Revolution and the establishment of the Russian Soviet Federative Socialist Republic (Russian SFSR), the capital was moved back to Moscow in 1918. The city later became the political center of the Soviet Union and experienced significant population growth throughout the Soviet period.
Astrocytes (from Ancient Greek ἄστρον, ástron, "star" and κύτος, kútos, "cavity", "cell"), also known collectively as astroglia, are characteristic star-shaped glial cells in the brain and spinal cord. They perform many functions, including biochemical control of endothelial cells that form the blood–brain barrier, provision of nutrients to the nervous tissue, maintenance of extracellular ion balance, regulation of cerebral blood flow, and a role in the repair and scarring process of the brain and spinal cord following infection and traumatic injuries. The proportion of astrocytes in the brain is not well defined; depending on the counting technique used, studies have found that the astrocyte proportion varies by region and ranges from 20% to around 40% of all glia. Another study reports that astrocytes are the most numerous cell type in the brain. Astrocytes are the major source of cholesterol in the central nervous system. Apolipoprotein E transports cholesterol from astrocytes to neurons and other glial cells, regulating cell signaling in the brain. Astrocytes in humans are more than twenty times larger than in rodent brains, and make contact with more than ten times the number of synapses. Research since the mid-1990s has shown that astrocytes propagate intercellular Ca2+ waves over long distances in response to stimulation, and, similar to neurons, release transmitters (called gliotransmitters) in a Ca2+-dependent manner. Data suggest that astrocytes also signal to neurons through Ca2+-dependent release of glutamate.

=== Glass Pasteur pipette === The two types of glass that are usually found in the laboratory and in the Pasteur pipette are borosilicate glass and soda–lime glass. Borosilicate glass is a widely used glass for laboratory apparatus, as it can withstand chemicals and temperatures used in most laboratories. Borosilicate glass is also more economical since the glass can be fabricated easily compared to other types. Soda lime glass, although not as chemically resistant as borosilicate glass, is suitable as a material for inexpensive apparatus such as the Pasteur pipette. Traditionally, glass Pasteur pipettes were made by heating lengths of glass tubing over a flame, before drawing them apart to form a long capillary. This capillary was further heated to bisect, producing two pipettes. Before the advent of rubber bulbs (also called teats) to generate a vacuum, liquid was drawn up through mouth suction. Nowadays, mouth-pipetting is either strongly discouraged or forbidden. Glass Pasteur pipettes can also be used for microscale filtration. By plugging the top (the larger aperture) with cotton or glass wool, a solution may pass through the pipette while insoluble sediment is retained. A rubber bulb may be employed to provide additional pressure if gravity is insufficient. Glass pasteur pipettes can be used to make spotters for thin layer chromatography after pulling it over a flame.
== Antimicrobial resistance == The misuse and overuse of antimicrobials in humans, animals and plants are the main drivers in the development of drug-resistant pathogens. Antimicrobial resistance (AR) occurs when microbes develop the ability to resist the drugs designed to kill them. AR has the potential to affect people at any stage of life, as well as the healthcare, veterinary and agriculture industries. This makes it one of the world's most urgent public health problems. Antimicrobial resistance mechanisms fall into four main categories: (1) limiting uptake of a drug; (2) modifying a drug target; (3) inactivating a drug; and (4) active drug efflux. It is estimated that bacterial antimicrobial resistance (AMR) was directly responsible for 1.27 million global deaths in 2019 and contributed to 4.95 million deaths.
Key State Department personnel grew increasingly frustrated with and suspicious of the Soviets as the war drew to a close. Averell Harriman, US Ambassador in Moscow, once a "confirmed optimist" regarding US–Soviet relations, was disillusioned by what he saw as the Soviet betrayal of the 1944 Warsaw Uprising as well as by violations of the February 1945 Yalta Agreement concerning Poland. Harriman would later have a significant influence in forming Truman's views on the Soviet Union. In February 1946, the US State Department asked George F. Kennan, then at the US Embassy in Moscow, why the Russians opposed the creation of the World Bank and the International Monetary Fund. He responded with a wide-ranging analysis of Russian policy now called the Long Telegram:
== Function == The major role of IGF-2 is as a growth promoting hormone during gestation. IGF-2 exerts its effects by binding to the IGF-1 receptor and to the short isoform of the insulin receptor (IR-A or exon 11-). IGF-2 may also bind to the IGF-2 receptor (also called the cation-independent mannose 6-phosphate receptor), which acts as a signalling antagonist; that is, to prevent IGF-2 responses. In the process of folliculogenesis, IGF-2 is created by thecal cells to act in an autocrine manner on the theca cells themselves, and in a paracrine manner on granulosa cells in the ovary. IGF-2 promotes granulosa cell proliferation during the follicular phase of the menstrual cycle, acting alongside follicle stimulating hormone (FSH). After ovulation has occurred, IGF-2 promotes progesterone secretion during the luteal phase of the menstrual cycle, together with luteinizing hormone (LH). Thus, IGF-2 acts as a co-hormone together with both FSH and LH. A study at the Mount Sinai School of Medicine found that IGF-2 may be linked to memory and reproduction. A study at the European Neuroscience Institute-Goettingen (Germany) found that fear extinction-induced IGF-2/IGFBP7 signalling promotes the survival of 17- to 19-day-old newborn hippocampal neurons. This suggests that therapeutic strategies that enhance IGF-2 signalling and adult neurogenesis might be suitable to treat diseases linked to excessive fear memory such as PTSD.

=== Assessment === Although CoQ10 may be measured in blood plasma, these measurements reflect dietary intake rather than tissue status. Currently, most clinical centers measure CoQ10 levels in cultured skin fibroblasts, muscle biopsies, and blood mononuclear cells. Culture fibroblasts can be used also to evaluate the rate of endogenous CoQ10 biosynthesis, by measuring the uptake of 14C-labeled p-hydroxybenzoate. CoQ10 is studied as an adjunctive therapy to reduce inflammation in periodontitis.
== Early career == Levé was born in Neuilly-sur-Seine on 1 January 1965. He was self-taught as an artist and studied business at the elite ESSEC Business School. He began painting in 1991. Levé made abstract paintings but abandoned the field (claiming to have burned most of his paintings) and took up color photography upon his return from an influential two-month trip to India in 1995.
Hooters, Inc., was incorporated in Clearwater, Florida, on April 1, 1983, by six Clearwater businessmen: Lynn D. Stewart, Gil DiGiannantonio, Ed Droste, Billy Ranieri, Ken Wimmer and Dennis Johnson. The date was an April Fools' Day joke because the original six owners believed that their prospect was going to fail. Their first Hooters restaurant was built on the site of a former rundown nightclub that had been purchased at a low price. So many businesses had folded in that particular location that the Hooters founders built a small "graveyard" at the front door for each that had come and gone before them. The first restaurant opened its doors on October 4, 1983, in Clearwater. This original location was decorated with memorabilia from Waverly, Iowa, hometown to some of the original Hooters 6. In December 1984, Hugh Connerty bought the rights to Hooters from the Original Hooters 6. Robert H. Brooks and a group of Atlanta investors (operators of Hooters of America, Inc.) bought out Hugh Connerty. In 2002, Brooks bought majority control and became chairman. The Clearwater-based company retained control over restaurants in the Tampa Bay Area, Chicago metropolitan area, and one in Manhattan, as well as rights to develop a Hooters casino and sell sauces in grocery stores, while all other locations were under the aegis of Hooters of America, which sold franchising rights to the rest of the United States and international locations. Under Brooks's leadership, the collective Hooters brand expanded to more than 425 stores worldwide.
== Research == Zalsupindole, as well as related drugs such as tabernanthalog (TBG; DLX-007), DLX-159, DLX-2270, and JRT, are licensed by Delix Therapeutics and are being developed for treatment of neuropsychiatric disorders such as depression and schizophrenia. As of January 2026, zalsupindole is in phase 1 clinical trials for major depressive disorder and other central nervous system disorders. Phase 1a and 1b trials have been completed and results reported. A phase 2 trial is being planned and has been cleared by the FDA for at home administration.
The supraoptic nucleus (SON) is a nucleus of magnocellular neurosecretory cells in the hypothalamus of the mammalian brain. The nucleus is situated at the base of the brain, adjacent to the optic chiasm. In humans, the SON contains about 3,000 neurons.

It is a synthetic REV-ERB agonist used mainly in preclinical research. It is not an approved medicine for human use.
It binds to REV-ERBα and REV-ERBβ, nuclear receptors involved in circadian and metabolic gene regulation. This can alter transcription of genes related to lipid and glucose metabolism in experimental models.
No controlled human trials have established that effect. Endurance findings come primarily from rodent studies, and human responses remain unknown.
Legality depends on the country and the intended use. In many places it is sold as a research chemical, but sports and medicine regulations restrict it.
