If you have been reading about REV-ERB and want a single page that covers the useful parts, this is it: definitions, context, how it is studied, and the questions that come up repeatedly.
Last reviewed on 2025-12-16. Where a claim depends on a specific study, the study is described rather than over-claimed.
Storage recommendations for SR9009 reference material typically specify a freezer at -20 °C or lower, with protection from moisture and light. Repeated freeze-thaw cycles can degrade small molecules and introduce variability. Stock solutions in dimethyl sulfoxide are often aliquoted to avoid repeated handling. Stability studies may examine degradation under heat, humidity, and light exposure. The compound's thiophene and nitro groups can participate in reactions that alter analytical signals over time, so such changes affect quantitative results.
Quality control for research materials includes identity confirmation by nuclear magnetic resonance and purity assessment by high-performance liquid chromatography. Mass spectrometry provides molecular weight confirmation and can detect related impurities. Purchasers should request a certificate of analysis that lists lot-specific data. Online products advertised for human use often lack such documentation. Distinguishing legitimate research material from mislabeled or contaminated samples is a recurring challenge in independent testing, and independent laboratories may use orthogonal methods to verify identity.
Detection of SR9009 in biological samples usually relies on liquid chromatography coupled to tandem mass spectrometry. This approach separates the compound from matrix components and identifies it by mass transitions. Because SR9009 can undergo metabolism, laboratories often look for both parent drug and specific metabolites. Sample preparation may involve protein precipitation or solid-phase extraction. Method validation examines sensitivity, carryover, and interference from related substances, and reference standards are required for accurate calibration.
The mechanism of action involves binding to REV-ERB receptors and recruiting corepressor complexes, which represses target gene transcription. This contrasts with many nuclear receptor agonists that activate transcription. Downstream effects may include changes in autophagy, mitochondrial biogenesis, and lipid handling, but the precise pathways remain an active area of study. Whether these molecular events translate into meaningful physiological effects in humans is unresolved. Most evidence comes from cultured cells and rodent models rather than human participants.
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.

Regulatory and sporting contexts treat SR9009 as a prohibited substance in many elite competitions. Its presence on banned lists reflects concerns about performance enhancement and unknown long-term safety. Analytical chemists have developed methods to detect the parent compound and its metabolites in urine and blood. Literature discussions distinguish between in vitro potency, animal pharmacology, and anecdotal human reports. The latter are difficult to verify because products sold online may lack purity or contain different compounds.
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, lipid metabolism, and inflammatory gene expression. In cell and animal experiments, SR9009 alters transcription of clock-controlled genes and metabolic pathways. The compound is not a hormone and does not resemble classical steroid structures. Its activity depends on binding to the ligand-binding domain of REV-ERB, where it can modify corepressor recruitment.
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.
Identity and purity testing for SR9009 commonly uses liquid chromatography coupled with tandem mass spectrometry. This method separates the compound from matrix components and detects it by mass-to-charge transitions, providing sensitive and specific confirmation. Nuclear magnetic resonance spectroscopy can support structural identification, while high-performance liquid chromatography with ultraviolet detection may estimate purity. Because online products labeled as SR9009 may contain other substances or no active compound at all, independent verification is important in research settings. Certificates of analysis are useful but not a substitute for in-house testing.
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.
Handling recommendations for SR9009 in a laboratory setting include storing the solid at low temperature, protected from light and moisture. The compound is often dissolved in dimethyl sulfoxide or ethanol for experiments. Solutions should be prepared with appropriate personal protective equipment and disposed of according to local rules. Stability data for long-term storage are limited, so stock solutions are typically kept cold and used within defined periods. Records of preparation date and concentration support reproducibility.
SR9009 is not approved as a medicine by major regulatory agencies. It is commonly sold as a research chemical, a category that may fall outside customary drug approval and quality rules. In sports, the World Anti-Doping Agency lists SR9009 as a prohibited substance. Athletes who use it can face sanctions if it is detected in a sample. Legal status varies by country, and importation may be restricted. Enforcement practices differ across borders.
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.
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.

Per Baseball Reference, Bagwell's 79.6 Wins Above Replacement (WAR) ranks sixth-most all-time among first basemen, trailing only Lou Gehrig, Albert Pujols, Jimmie Foxx, Cap Anson, and Roger Connor. He spent the first nine seasons of his career (1991–99) playing home games at the Astrodome, notorious for its reputation as the toughest park in which to hit when baseball was still played there. However, during those nine years, his production at home was nearly identical to his production on the road. In that same period of time, his 160 OPS+ was fourth behind Bonds, McGwire, and Frank Thomas; his 56.7 WAR was third behind Bonds and Ken Griffey Jr. From 1994 to 2000, a span including his age-26 through age-32 seasons, he averaged 41 home runs and 41 doubles per 162 games while batting .309, .433 OBP, and .593 SLG for a 167 OPS+. Over his career, Bagwell batted at least .300 six times, amassed a 1.000 OPS five times, collected at least 30 home runs eight times, 100 RBI eight times, 100 runs scored nine times, and 100 walks seven times. He is the only player in history to achieve six consecutive seasons (1996–2001) with each of 30 home runs, 100 RBI, 100 runs scored, and 100 walks. Bagwell had seven seasons with 30 home runs and 100 walks; the only players with more are Gehrig, Ruth, Williams, Jim Thome, and Thomas. Bagwell is one of 12 players in MLB history to hit at 400 home runs and attain a career on-base percentage of at least .400. The only National League first baseman to reach the 30–30 club, he is the only first baseman in history to do it twice.
=== Cancer and Infectious Diseases === A significant area of LMRT's work involves developing nanomaterials as tools for biological studies and as multifunctional agents for cancer therapies. This includes designing nanoparticles and nanoporous materials that can home in on tumors, signal cellular changes, enhance imaging, or deliver therapeutic components. Early work in 2002, with Erkki Ruoslahti, involved developing phage-derived peptide-targeted nanomaterials for in vivo tumor targeting. More recently, Bhatia, in collaboration with Erkki Ruoslahti and Michael Sailor, has explored engineering beneficial probiotics to detect or treat cancer cells. For over a decade, LMRT has pioneered new technologies in activity-based diagnostics. This includes designing nanosensors with biological molecules, such as peptide barcodes, that can signal the presence of diseases like cancer when interacting with aberrantly active enzymes (proteases) in diseased tissue. These specialized nanoparticles allow for detection via simple tests on urine similar to an at-home pregnancy test, breath, or blood samples. This platform has expanded to detect 12 diseases, including 6 cancer types. Nanosensors can be administered via inhalation, intramuscular injection, and even ingested in the form of probiotic bacteria. The LMRT is also exploring breath-based diagnostics for rapid results and has developed diagnostic tools that use DNA barcodes and CRISPR technology, making cancer diagnostics more affordable and accessible for low- and middle-resource settings.

=== Football clubs === In the 1960s, Inter Milan has its greatest period of success known as [La] Grande Inter ("Great Inter"), achieved when Helenio Herrera was their manager. He won seven trophies with the club. In 2004, Ferruccio Mazzola, Inter player during that period, accused him of distributing performance-enhancing drugs, including amphetamines, among the team players, especially the substitute players "who often served as guinea pigs for trying new pills and see if they worked." When he found out that some in the team were spitting them out, he dissolved them in coffee to make sure they were consumed, a practice known as Caffè di Herrera ("Herrera's Coffee"). In 2010, Inter sued Mazzola but lost the case, the court believed him. One of the reasons he spoke up were the serious medical conditions and/or deaths of some of his former members: Giuliano Taccola, then team's captain Armando Picchi (died aged 36 due to cancer), Marcello Giusti, Carlo Tagnin, Mauro Bicicli, Ferdinando Miniussi, Enea Masiero and Pino Longoni. He suspected the drugs to be the cause of their sufferings. in 2015, his brother Sandro, who denied everything at the beginning, admitted that the incidents happened. In the 1970s performance-enhancing drugs were used on a regular basis according to witnesses of that period, mostly in Ajax, Feyenoord and AZ Alkmaar during competitive matches, including the 1970 and 1972 Intercontinental Cups won by the first two cited clubs. Jan Peters recounted drug use before the big games. They seemed to work as he felt energy boosts and euphoria.
==== Kiln drying schedules ==== Satisfactory kiln drying can usually be accomplished by regulating the temperature and humidity of the circulating air to control the moisture content of the lumber at any given time. This condition is achieved by applying kiln-drying schedules. The desired objective of an appropriate schedule is to ensure drying lumber at the fastest possible rate without causing objectionable degrade. The following factors have a considerable bearing on the schedules.
=== Biosynthesis === Chloramphenicol is produced by Streptomyces venezuelae. Its biosynthesis has been partially elucidated. A portion of the structure originates from the shikimate pathway, in which aromatic amino acids are formed. The non-proteinogenic amino acid para-aminophenylalanine is also accessible via this pathway (step 1 in the scheme). This intermediate is bound to a peptidyl carrier protein via a thioester (2) and hydroxylated at the benzyl position (3). The amino group is then oxidized to the nitro group (4), the dichloroacetyl group is introduced from an unknown precursor (5), and the intermediate is released as an aldehyde (6). Reduction of the aldehyde group to the alcohol (7) yields chloramphenicol.
Medazepam is a drug that is a benzodiazepine derivative. It possesses anxiolytic, anticonvulsant, sedative, and skeletal muscle relaxant properties. It is known by the following brand names: Azepamid, Nobrium, Tranquirax (mixed with bevonium), Rudotel, Raporan, Ansilan and Mezapam. Medazepam is a long-acting benzodiazepine drug. The half-life of medazepam is 36–200 hours.
In most cases, urinary retention is managed with dose reduction or by switching to another type of antidepressant. In extreme cases, patients may require treatment with bethanechol, a drug that reverses this particular side effect. A common problem with TCAs is sedation (drowsiness, lack of physical and mental alertness), but protriptyline is considered the least sedating agent among this class of agents. Its side effects are especially noticeable early in therapy. In most people, early TCA side effects decrease or disappear entirely with time, but, until then, patients taking protriptyline should take care to assess which side effects occur in them and should not perform hazardous activities requiring mental acuity or coordination. Protriptyline may increase the possibility of having seizures.

Additional requirements for rations include having a minimum shelf life of three years, being deliverable by air, being consumable in worldwide environments, and providing a complete nutritional profile. The new T-rations have been improved upon by increasing acceptable items and provide high quality meals while in the field. Freeze-dried coffee was also incorporated by replacing spray-dried coffee in the Meal, Ready-to-Eat category.
Jerky is made from domesticated animals as well as game animals. Jerky from domesticated animals includes llama, beef, pork, goat and mutton or lamb and game animals such as guanaco, deer, kudu, springbok, kangaroo, and bison are also used. Other animals such as turkey, ostrich, calamari, salmon, chicken, duck, goose, shrimps, oxen, squids, octopuses, alligator, pigeon, crocodile, tuna, emu, horse, camel, lion, bear, snake and earthworm have entered the global, national, regional or local market with varying degrees of success. Most fat must be trimmed from the meat prior to drying, as fat increases the chances of spoilage (modern vacuum packing and chemical preservatives have served to help prevent these risks). The meat must be dried quickly to limit bacterial growth during the critical period when the meat is not yet dry. To dry quickly without high temperature, which would cook the meat, the meat must be sliced or pressed thin. Salt is the most commonly added ingredient and is used to improve flavor, enhance the storage life and remove moisture from the product. Spices such as black pepper or garlic are other common ingredients. Ingredients such as soy sauce, Worcestershire sauce, sugar, teriyaki or barbecue spice can be added to change the flavor and are usually employed in homemade beef jerky recipes. In industrial settings, large low-temperature drying ovens with many heater elements and fans use exhaust ports to remove moisture-laden air. The combination of fast-moving air and low heat dries the meat to the desired moisture content within a few hours.
