Everything below concerns storage stability. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2026-04-09. Where a claim depends on a specific study, the study is described rather than over-claimed.
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.
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.
| Property | Value | Notes |
|---|---|---|
| Chemical class | Synthetic REV-ERB agonist | Small molecule; not a steroid or peptide. |
| Primary targets | NR1D1 and NR1D2 | Also known as REV-ERBα and REV-ERBβ. |
| Studied routes | Intraperitoneal in rodents | Oral bioavailability in humans is not established. |
| Human approval | No approved therapeutic indication | No recognized clinical use. |
| Key uncertainty | Human physiological effects | Preclinical findings may not translate. |
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 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.
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.
=== Efficacy of abrocitinib in treating atopic dermatitis === According to the latest meta-analysis in 2023, abrocitinib is both efficient and safe in treating moderate-to-severe AD in adolescents and adults. It also relieves itching rapidly and alleviates symptoms of AD. Abrocitinib gives significantly better results than the placebo at both 100 mg and 200 mg. The severity of AD is quantified through Eczema Area and Severity Index (EASI), which is based on the severity of lesion clinical signs. Abrocitinib was more effective than placebo in terms of EASI-reduction, but it also decreased other symptoms. The improvement of depression and anxiety was better in the experimental group than that in the control group. In another meta-analysis including 2256 patients from three different studies have shown that abrocitinib improved the EASI scores in comparison with dupilumab, even in the second week of treatment. A faster onset of Investigator's Global Assessment (IGA) response at the second week was also achieved by administering abrocitinib and early relief of itching occurred at 2 weeks. In other studies, abrocitinib (200 mg dose) achieved rapid relief from itching after four days of treatment compared with dupilumab and placebo in AD patients.
== Plot == Rick Rambis, best friend Luke, and other friends Anthony, "Pig Pen", Jenny, Lance and Stumpy, all live and work at a ski resort on Bull Mountain in Alaska. The mountain and resort were founded by Herbert "Papa" Muntz who stole the land from the Eskimos and loved to drink and ski at the same time until he died doing so. His son, Ted, took over the mountain and plans to sell it to wealthy Colorado ski resort tycoon John Majors. In addition to being friends, Rick has romantic designs on Jenny, but is held back as he is still getting over his ex, Anna, who mysteriously disappeared after 3 weeks of summer love in Mexico. After arriving at the mountain, John Majors plans to change the mountain name and turn the ski village into a first class resort but seeks Rick's help in getting his rowdy friends in line so as not to scare off his investors. John brings with him to the mountain his daughters, Inga, a Swiss ski bunny, and Anna, Rick's summer fling. After Anna's arrival, Rick then gets drunk and misses his date with Jenny. Later, Anna explains she left Rick in Mexico because she was already engaged to a doctor named Barry, who suffered an injury during the X Games, now a wheelchair user, and that Rick was the other man. Majors begins to make major changes to the town and mountain, such as changing the dive bar to an upscale club called Powder Room, removing the statue of Papa Muntz from the center of the town, and evicting some folks from their homes. Majors offers Rick a contract to be his new manager and Rick agrees on the condition that his friends all get to stay.
Charlemagne founded the Carolingian Empire in 800; it was divided in 843. The eastern successor kingdom of East Francia stretched from the Rhine in the west to the Elbe river in the east and from the North Sea to the Alps. Subsequently, the Kingdom of Germany and the Holy Roman Empire emerged from it. The Ottonian rulers (919–1024) consolidated several major duchies. In 996, Gregory V became the first German Pope, appointed by his cousin Otto III, whom he shortly after crowned Holy Roman Emperor. The Holy Roman Empire absorbed northern Italy and Burgundy under the Salian emperors (1024–1125), although the emperors lost power through the Investiture Controversy. Under the Hohenstaufen emperors (1138–1254), German princes encouraged German settlement to the south and east (Ostsiedlung). Members of the Hanseatic League, mostly north German towns, prospered in the expansion of trade. The population declined starting with the Great Famine in 1315, followed by the Black Death of 1348–1350. The Golden Bull issued in 1356 provided the constitutional structure of the Empire and codified the election of the emperor by seven prince-electors. Johannes Gutenberg introduced moveable-type printing to Europe, laying the basis for the democratisation of knowledge. Following Martin Luther's 1517 Protestant Reformation, bolstered by his standardised Bible translation, led to the 1555 Peace of Augsburg, which recognised Lutheranism under the principle of cuius regio, eius religio (ruler's faith dictates subjects' faith).

=== Moisture === Excessive and continuous skin moisture can pose a risk to compromise the integrity of the skin by causing the skin tissue to become macerated and therefore be at risk for epidermal erosion. So this category assesses the degree of moisture the skin is exposed to.
On September 22, on the first-ever Raw to be broadcast from Madison Square Garden, McMahon told Austin he wasn't physically cleared to compete, and after several weeks of build-up, Austin delivered his Stone Cold Stunner to McMahon, causing the fans in attendance to go ballistic. Austin was then arrested as part of the storyline, and was sidelined until Survivor Series. However, in the interim, he made several appearances, one being at Badd Blood where he was involved in the finish of a match between Owen and Faarooq for the vacant Intercontinental Championship. Austin hit Faarooq with the Intercontinental Championship belt while the referee's back was turned, causing Hart to win the match and the title. Austin's motive was to keep Owen as champion, as demonstrated when he interfered in Hart's matches on Raw. Austin regained the Intercontinental Championship from Hart at Survivor Series. With Owen Hart out of the way, Austin set his sights on The Rock, who stole Austin's championship belt after Austin suffered a beating by his Nation of Domination stablemates. In the weeks to come, The Rock began declaring himself to be "the best damn Intercontinental Champion ever." The Rock kept possession of the championship belt until D-Generation X: In Your House, when Austin defeated him to retain the championship and regain the belt. As Austin had used his pickup truck to aid his victory, McMahon ordered him to defend the championship against The Rock the next night on Raw.
== Chemistry == DET, also known as N,N-diethyltryptamine, is a synthetic compound in the tryptamine class, structurally related to the endogenous neurotransmitter serotonin and the naturally occurring psychedelic compounds dimethyltryptamine (DMT) and dipropyltryptamine (DPT). It is the ethyl analogue of DMT.

In its open, inactive form, the active site structure forms a loop while one subunit adopts an asymmetric open conformation and the other adopts a quasi-open conformation. This conformation enables isocitrate to bind the active site, inducing a closed conformation that also activates IDH1. In its closed, inactive form, the active site structure becomes an α-helix that can chelate metal ions. An intermediate, semi-open form features this active site structure as a partially unraveled α-helix. There is also a type 1 peroxisomal targeting sequence at its C-terminal that targets the protein to the peroxisome.
== Side effects == In studies, the most serious side effects of the combination olaratumab/doxorubicin were neutropenia (low count of neutrophil white blood cells) with a severity of grade 3 or 4 in 55% of patients, and musculoskeletal pain grade 3 or 4 in 8% of patients. Common milder side effects were lymphopenia, headache, diarrhoea, nausea and vomiting, mucositis, and reactions at the infusion site; all typical effects of cancer therapies.
Starting to breastfeed may be challenging for mothers of preterm infants, especially those born before 34 weeks, because their breasts may still be developing (in Lactogenesis I, see Breastfeeding Physiology). Additionally, mother–infant separation and the stressful environment of the NICU are also barriers to breastfeeding. Availability of a lactation specialist in the NICU can be helpful for mothers trying to establish their milk supply. Additionally, skin-to-skin (Kangaroo Care) is safe and beneficial to both mother and baby. Kangaroo Care stabilizes newborn premature infants' vital signs, such as their heart rate, providing a naturally warm environment that helps them regulate their temperature. It is also beneficial to the mother, as it may improve the development of milk supply and be beneficial for mental health.

It is a synthetic compound that acts as an agonist at REV-ERBα and REV-ERBβ. It is used mainly as a research chemical to study circadian and metabolic pathways. It is not approved for human therapeutic use.
REV-ERB receptors generally repress transcription when bound by natural heme. SR9009 is described as an agonist that enhances this repressive activity. The result is altered expression of clock and metabolic genes.
Published controlled human trials are lacking. Some sources cite limited or unofficial reports, but these do not establish safety or efficacy. Claims about human performance effects remain unverified.
Research-grade SR9009 is typically stored frozen at about minus twenty degrees Celsius, protected from light and moisture. Stock solutions are often kept in aliquots to avoid repeated freeze-thaw cycles. Specific storage conditions should follow the supplier's documentation.
