SR9009 is a synthetic small molecule studied as a REV-ERB agonist. REV-ERBα and REV-ERBβ are nuclear receptors that help regulate circadian rhythms and metabolic gene expression. The compound was identified in academic screening efforts to find synthetic ligands for these receptors. In cell and animal studies, SR9009 alters transcription of genes involved in lipid and glucose metabolism, and it can shift circadian behavior. It is not an approved therapeutic agent.
Mechanistically, SR9009 binds the ligand-binding domain of REV-ERBα/β and enhances recruitment of corepressor complexes. This represses target genes rather than activating them. Because REV-ERB proteins normally compete with ROR proteins at shared response elements, the net effect depends on tissue and timing. Researchers use SR9009 to probe how nuclear receptor signaling links the clock to metabolism, inflammation, and muscle biology. Findings are largely preclinical, and the precise contribution of each receptor subtype remains under study.
Research interest in SR9009 grew from studies of circadian biology and metabolic disease. Preclinical reports describe effects on exercise capacity, muscle metabolism, and blood lipid levels in rodents, but these findings come from controlled laboratory settings. The compound has low oral bioavailability in animals, which limits systemic exposure after swallowing. Investigators often use injected routes in experiments to achieve measurable plasma concentrations. Human clinical data are sparse, no approved therapeutic product exists, and whether animal effects translate to humans remains an open question.
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.

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.
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.
Handling practices for SR9009 focus on minimizing degradation and contamination. The solid is generally stored desiccated at or below -20 °C, protected from light and moisture. Stock solutions are often prepared in dimethyl sulfoxide or ethanol, then aliquoted to avoid repeated freeze–thaw cycles. Aqueous solubility is low, so formulations for animal studies may require cosolvents or suspending agents. Personnel should follow institutional chemical safety procedures, because toxicological data for humans are incomplete.
Regulatory status varies by country and intended use. Major drug agencies have not granted marketing authorization for SR9009 as a medicine, and it is not listed as a controlled substance in many jurisdictions. It is often sold as a research chemical, a category that may fall outside pharmaceutical manufacturing rules. Buyers should verify local laws and supplier documentation, including certificates of analysis. The lack of standardized quality controls raises concerns about identity, purity, and actual content in products marketed online.
In laboratory settings, SR9009 is commonly identified by its molecular structure and its interaction with REV-ERB receptors. Vendors may list it under synonyms such as Stenabolic or REV-ERB agonist, but those names do not define purity or identity. Analytical confirmation typically uses high-performance liquid chromatography with ultraviolet detection or liquid chromatography–mass spectrometry. A reference standard is needed to compare retention time and mass spectrum, because the compound can be confused with related research chemicals.
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.
Analytical chemists detect SR9009 with liquid chromatography-tandem mass spectrometry, commonly abbreviated LC-MS/MS. Sample preparation may involve protein precipitation, liquid-liquid extraction, or solid-phase extraction before analysis. Laboratories can target the parent compound or its metabolites, depending on the matrix and the purpose of testing. Anti-doping methods require sensitive and specific assays because concentrations in biological samples can be low. Reference standards and validated methods are essential for reliable identification and quantification.
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.
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.
Trump issued NSPM-7 (National Security Presidential Memorandum-7) on September 25, 2025, directing a government-wide strategy to counter what it characterizes as organized domestic terrorism and political violence. The memorandum cites "common threads" such as "anti-Americanism", "anti-capitalism", "anti-Christianity", support for 'overthrowing' the United States Government, and extremism related to migration, race, and gender. It assigns the National Joint Terrorism Task Force to lead investigations, directs the United States Department of Justice to prioritize prosecutions and consider domestic terrorist organization designations, and instructs the Department of the Treasury and the Internal Revenue Service to disrupt financial networks, while noting that the directive creates no enforceable rights. Thirty-one members of Congress later warned in a letter that NSPM-7 raises constitutional and civil-liberties concerns if used to target political dissent or ideological speech.
=== 2000: Glaxo Wellcome and SmithKline Beecham merger === Glaxo Wellcome and SmithKline Beecham announced their intention to merge in January 2000. The merger was completed on 27 December that year, forming GlaxoSmithKline (GSK). The company's global headquarters were at GSK House, Brentford, London, officially opened in 2002, by then-Prime Minister Tony Blair. The building was erected at a cost of £300 million and as of 2002 was home to 3,000 administrative staff.
=== Mechanism of action === Tirzepatide has a greater affinity to GIP receptors than to GLP-1 receptors, and this dual agonist behavior has been shown to produce greater reductions of hyperglycemia compared to a selective GLP-1 receptor agonist. Signaling studies reported that tirzepatide mimics the actions of natural GIP at the GIP receptor. At the GLP-1 receptor, though, tirzepatide shows bias toward cAMP (a messenger associated with regulation of glycogen, sugar, and lipid metabolism) generation rather than β-arrestin recruitment. This combination of preference toward GIP receptor and distinct signaling properties at GLP-1 suggest this biased agonism increases insulin secretion. Tirzepatide has been reported to increase levels of adiponectin, an adipokine involved in the regulation of both glucose and lipid metabolism, with a maximum increase of 26% from baseline after 26 weeks, at the 10 mg dosage.
=== Dependence and withdrawal === Tolerance to phenibut easily develops with repeated use, leading to dependence. Withdrawal symptoms may occur upon discontinuation, and, in recreational users taking high doses, have been reported to include severe rebound anxiety, insomnia, aggression, irritability, agitation, visual and auditory hallucinations, seizures and acute psychosis. Baclofen has successfully been used for treatment of phenibut dependence.

A section of the report pertaining to the internal functioning of the S&D Group was held over until September 2023 to allow for a discussion of its findings with the S&D Bureau prior to its publication.
Domino's announced on February 7, 2025, that it plans to close more than 200 stores worldwide, 172 of them just in Japan, where Domino's Pizza Japan operates 1,000 stores. The decision comes after CEO and Managing Director Mark van Dyck took the reins of the company. The reason given for the closure was low sales in the selected stores. Of all the markets that include the brand, Australia–New Zealand was the only market to report positive growth. With the closures, Domino's expects to reduce costs by approximately $9.8 million.
Stigmata (Ancient Greek: στίγματα, plural of στίγμα stigma, 'mark, spot, brand'), in Roman Catholicism, are bodily wounds, scars and pain which appear in locations corresponding to the crucifixion wounds of Jesus Christ: the hands, wrists, feet, near the heart, the head (from the crown of thorns), and back (from carrying the cross and scourging). St. Francis of Assisi is widely considered the first recorded stigmatic. For over fifty years, St. Padre Pio of Pietrelcina of the Order of Friars Minor Capuchin reported stigmata which were studied by several 20th-century physicians. Stigmatics are primarily a Roman Catholic phenomenon; the Eastern Orthodox Church professes no official view on them. A high percentage (probably over 80%) of all stigmatics are women. In his book Stigmata: A Medieval Phenomenon in a Modern Age, Ted Harrison suggests that there is no single mechanism whereby the marks of stigmata were produced. What is important is that the marks are recognised by others as being of religious significance. Most cases of stigmata have been the result of trickery and fraud. Some cases have also included reportings of a mysterious chalice in visions being given to stigmatics to drink from or the feeling of a sharp sword being driven into one's chest.

=== Particle accelerators === The feasibility of technetium-99m production with the 22-MeV-proton bombardment of a molybdenum-100 target in medical cyclotrons following the reaction 100Mo(p,2n)99mTc was demonstrated in 1971. The recent shortages of medical technetium-99m reignited the interest in its production by proton bombardment of isotopically enriched (>99.5%) molybdenum-100 targets. Other techniques are being investigated for obtaining molybdenum-99 from molybdenum-100 via (n,2n) or (γ,n) reactions in particle accelerators.
== Early years and education == Muñoz, was born in Lima, Peru. In 1996, she attended the National University of San Marcos (UNMSM), where she earned her pharmaceutical degree. While studying, she developed an interest in the field of nutrition. She earned a master's degree in biochemistry and nutrition, and earned a PhD in Pharmacy and Biochemistry from the National University of San Marcos (UNMSM) in 2006.
== Side effects == The most common side effects include lymphadenopathy (swollen lymph nodes), itching, pain, oedema, and bleeding (for example in the form of bruises or ecchymoses). Allergic reactions are seen in less than 1% of patients. In Peyronie's disease, potential side effects include corporal rupture (penile fracture) or other serious penile injury.
== Diagnosis == There are two types of cystocele. The first is distension. This is thought to be due to the overstretching of the vaginal wall and is most often associated with aging, menopause and vaginal delivery. It can be observed when the rugae are less visible or absent. The second type is displacement. Displacement is the detachment or abnormal elongation of supportive tissue. The initial assessment of cystocele can include a pelvic exam to evaluate leakage of urine when the women is asked to bear down or give a strong cough (Valsalva maneuver), and the anterior vaginal wall measured and evaluated for the appearance of a cystocele. If a woman has difficulty emptying her bladder, the clinician may measure the amount of urine left in the woman's bladder after she urinates called the postvoid residual. This is measured by ultrasound. A voiding cystourethrogram involves taking X-rays of the bladder during urination. This X-ray shows the shape of the bladder and lets the doctor see any problems that might block the normal flow of urine. A urine culture and sensitivity test will assess the presence of a urinary tract infection that may be related to urinary retention. Other tests may be needed to find or rule out problems in other parts of the urinary system. Differential diagnosis will be improved by identifying possible inflammation of the Skene's glands and Bartholin glands.
