In rodent studies, SR9009 has been reported to increase mitochondrial content in skeletal muscle and improve exercise endurance under some conditions. These findings led to popular descriptions such as an exercise mimetic, although that term oversimplifies the biology. Effects vary by dose, timing, tissue, and model. The compound's influence on circadian pathways means that time of administration can matter in experiments. Whether similar metabolic changes occur in humans remains largely unexplored in controlled published trials.
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 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.
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.
| Property | Value | Notes |
|---|---|---|
| Chemical class | Synthetic small-molecule REV-ERB agonist | Not a hormone or natural product |
| Primary targets | REV-ERBα and REV-ERBβ | Nuclear receptors involved in circadian and metabolic regulation |
| Appearance | White to off-white solid | Typical for purified research samples |
| Solubility | Soluble in DMSO and ethanol; low water solubility | Laboratory solubility depends on solvent and purity |
| Common synonyms | SR9009; Stenabolic | Stenabolic is a colloquial name, not a formal chemical name |
Regulatory agencies have not approved SR9009 for human therapeutic use. It is typically sold as a research chemical with labels stating that it is not for human consumption. The World Anti-Doping Agency prohibits the substance in sport, generally under the category of non-approved substances. Customs and national laws may restrict importation, sale, or possession. Product quality and legal status can vary by country and vendor, and therapeutic claims are not permitted in regulated advertising because the compound lacks approval.
Several misconceptions surround SR9009. It is often described as a SARM, a steroid, or an exercise pill, but its known target is the REV-ERB receptor family. Rodent studies have examined exercise capacity and metabolic markers, yet human outcomes remain unproven. Oral bioavailability appears low in animals, and human pharmacokinetics are not well characterized. Online products may contain impurities or different compounds, so identity and purity testing are important for research use.
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 studies often administer SR9009 by injection because oral absorption appears poor in rodents. Reported pharmacokinetic properties include rapid metabolism and low systemic exposure after oral dosing. Human pharmacokinetic data are sparse, so absorption, distribution, metabolism, and excretion in people are not well defined. Some research explores related REV-ERB compounds with improved drug-like properties. Regulatory approval for any REV-ERB agonist as a human medicine has not been granted to date.
SR9009 is a synthetic small molecule studied as an agonist of the nuclear receptors REV-ERBα and REV-ERBβ, also called NR1D1 and NR1D2. These receptors help regulate circadian rhythms and metabolic gene programs. The compound was developed for laboratory research, not as an approved therapeutic. Its identity is distinct from steroid hormones and selective androgen receptor modulators. Scientific interest centers on how REV-ERB activation changes gene expression in cells and animal models.
Origin of replication: Necessary for the replication and maintenance of the vector in the host cell. Promoter: Promoters are used to drive the transcription of the vector's transgene as well as the other genes in the vector such as the antibiotic resistance gene. Some cloning vectors need not have a promoter for the cloned insert but it is an essential component of expression vectors so that the cloned product may be expressed. Cloning site: This may be a multiple cloning site or other features that allow for the insertion of foreign DNA into the vector through ligation. Genetic markers: Genetic markers for viral vectors allow for confirmation that the vector has integrated with the host genomic DNA. Antibiotic resistance: Vectors with antibiotic-resistance open reading frames allow for survival of cells that have taken up the vector in growth media containing antibiotics through antibiotic selection. Epitope: Some vectors may contain a sequence for a specific epitope that can be incorporated into the expressed protein. It allows for antibody identification of cells expressing the target protein. Reporter genes: Some vectors may contain a reporter gene that allow for identification of plasmid that contains inserted DNA sequence. An example is lacZ-α which codes for the N-terminus fragment of β-galactosidase, an enzyme that digests galactose. A multiple cloning site is located within lacZ-α, and an insert successfully ligated into the vector will disrupt the gene sequence, resulting in an inactive β-galactosidase.
From this revolution, the 1950s also saw the advent of paper chromatography, reversed-phase partition chromatography (RPC), and hydrophobic interaction chromatography (HIC). The first gels for use in LC were created using cross-linked dextrans (Sephadex) in an attempt to realize Synge's prediction that a unique single-piece stationary phase could provide an ideal chromatographic solution. In the 1960s, polyacrylamide and agarose gels were created in a further attempt to create a single-piece stationary phase, but the purity of and stability of available components did not prove useful for implementation in the HPLC. In this decade, affinity chromatography was invented, an ultra-violet (UV) detector was used for the first time in conjunction with LC, and, most importantly, the modern HPLC was born. Csaba Horvath led the development of modern HPLC by piecing together laboratory equipment to suit his purposes. In 1968, Picker Nuclear Company marketed the first commercially available HPLC as a “Nucleic Acid Analyzer.” The following year, the first international symposia on HPLC was held, and Kirkland at DuPont was able to functionalize controlled porosity pellicular particles for the first time. The 1970s and 1980s witnessed a renewed interest in separations media with reduced interparticular void volumes. Perfusion chromatography showed, for the first time, that chromatography media could support high flow rates without sacrificing resolution. Monoliths aptly fit into this new class of media, as they exhibit no void volume and can withstand flow rates up to 9mL/minute.

These three receptors have been renamed as FPR1, FPR2, and FPR3 and found to have very different specificities for the formyl oligopeptides and very different functions that include initiating inflammatory responses to N-formyl peptides released not only by bacteria but also a multiplicity of elements released by host tissues; dampening and resolving inflammatory responses; and perhaps contributing to the development of certain neurological cancers and an array of neurological diseases Amyloid-based diseases.
Research on vitamin C in the common cold has been divided into effects on prevention, duration, and severity. Oral intakes of more than 200 mg/day taken on a regular basis was not effective in prevention of the common cold. Restricting analysis to trials that used at least 1000 mg/day also saw no prevention benefit. However, taking a vitamin C supplement on a regular basis did reduce the average duration of the illness by 8% in adults and 14% in children, and also reduced the severity of colds. Vitamin C taken on a regular basis reduced the duration of severe symptoms but had no effect on the duration of mild symptoms. Therapeutic use, meaning that the vitamin was not started unless people started to feel the beginnings of a cold, had no effect on the duration or severity of the illness. Vitamin C distributes readily in high concentrations into immune cells, promotes natural killer cell activities, promotes lymphocyte proliferation, and is depleted quickly during infections, effects suggesting a prominent role in immune system function. The European Food Safety Authority concluded there is a cause and effect relationship between the dietary intake of vitamin C and functioning of a normal immune system in adults and in children under three years of age.

==== Metabolism and interactions ==== Deruxtecan is metabolised by CYP3A4, without notable glucuronidation. Moreover, it is a substrate of several transporter systems, i.e. OATP1B1, OATP1B3, MATE2-K, P-gp, MRP1 and BCRP. Therefore, use with itraconazole (CYP3A inhibitor) and ritonavir (OATP1B/CYP3A inhibitor) is contraindicated.
In a letter to Crick on 11 December 1954, discussing how RNA could be produced from DNA since they contain fundamentally similar nucleotide compositions, he wrote: "I suspect the answer is staring us in the face." To solve the riddle of protein synthesis, Gamow (as the Synthesiser) created an informal team of scientists which he called the RNA Tide Club in 1954. As his prediction to denote 20 amino acids, the club could have only 20 members, with the designated officers: Crick (as the Pessimist), Rich (the Lord Privy Seal) and Watson (the Optimist) among them. It was meant partly to be humorous.
=== Informants and holdouts === Also targeted were civilians suspected of being informants of the apartheid police. Alongside petrol bombs, necklacing became a favoured method of executing such suspects. In one early example known nationwide, a young woman in Duduza, Maki Skosana, was necklaced on 20 July 1985 at a funeral for a local activist; a television crew filmed a crowd of young men kicking and beating her, tearing her clothes off, dousing her in petrol, and then setting her alight while one man rammed a glass bottle into her vagina. Skosana was rumoured to be the girlfriend and co-conspirator of Joe Mamasela, a notorious askari who had killed several Duduza youths by hand grenade in an entrapment operation in June. In addition, though mass action had broad support during this period, there were frequently complaints that the reluctant were compelled to participate in stay-aways or boycotts by force or intimidation. Groups of COSAS supports were accused of "erecting barricades to prevent residents from going to work; attacking those who tried to do so; moving from school to school ordering students out of class; hurling stones and petrol bombs at policemen; attacking buses and taxis; digging trenches in the streets; destroying buildings; and assaulting members of rival organisations". There was also evidence that vigilante attacks were sometimes perpetrated on the basis of mere political or personal "grudges".

=== Foreign operations in China === Mengniu-Arla, a joint-venture between Danish/Swedish co-operative Arla Foods and Mengniu halted production on 16 September 2008 after three of 28 tests taken from Mengniu showed traces of melamine; the contaminated batches had been recalled. Mengniu, milk supplier to Starbucks, was replaced by Vitasoy when the coffee retailer eschewed milk in favour of soya milk in its China operations. KFC also suspended selling Mengniu milk. Seoul-headquartered Lotte Group, a major snacks maker, recalled its Koala's March cookies in Hong Kong and Macau because of contamination, and promised to "look deeply into all the details of the manufacturing process" to preserve customer confidence. The range was also ordered off Dutch and Slovak shelves. Other products were seized when samples tested positive in Malta. On 29 September, British confectionery group Cadbury recalled all chocolate products made in its Chinese factories due to concerns about melamine contamination, affecting products intended for markets in China, Taiwan, Hong Kong, Japan, Korea and Australia. Tests in Hong Kong found amounts of melamine in China-made Dairy Milk products which exceeded safety regulations. On 30 September, Unilever recalled its Lipton milk tea powder after the company's internal checks found traces of melamine in the Chinese powdered milk used as an ingredient. Heinz recalled cases of baby cereal in Hong Kong after discovering they contained melamine.
== Use == Functional beverages are commonly consumed by people seeking health benefits from their foods and beverages. Both convenience and health have been identified as important factors in consumers' decision-making about food and beverage purchases. Functional drinks are advertised as having various health benefits. For example, some claim to improve heart health, immunity, digestion, and joint health, while others promote themselves as satiating and energy-boosting.

Chronic use may result in cocaine dependence, withdrawal symptoms, neurotoxicity, and nasal damage, including cocaine-induced midline destructive lesions. Coca cultivation and initial processing occur primarily in Latin America, especially in the Andes regions of Bolivia, Peru, and Colombia. Cultivation is expanding into Central America, including Honduras, Guatemala, and Belize. Violence linked to the cocaine trade continues to affect Latin America and the Caribbean and is expanding into Western Europe, Asia, and Africa as transnational organized crime groups compete globally. Cocaine remains the world's fastest-growing illicit drug market. Coca chewing dates back at least 8,000 years in South America. Large-scale cultivation occurred in Taiwan and Java prior to World War II. The cocaine boom—a sharp rise in illegal production and trade—began in the late 1970s and peaked in the 1980s. Cocaine is regulated under international drug control conventions, though its legal status varies nationally: several countries have decriminalized possession of small quantities.

It is a synthetic research compound that activates REV-ERB nuclear receptors. It is not an approved drug or dietary supplement. Most information comes from cell and animal studies.
It binds REV-ERBα and REV-ERBβ and changes transcription of metabolic genes. This can affect circadian rhythm, lipid use, and mitochondrial function. The full downstream effects are still under study.
No. Some rodent studies show increased endurance, but controlled human trials are lacking. Claims about human performance are not established by published evidence.
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.
