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.
At the molecular level, SR9009 binds the ligand-binding domain of REV-ERB and strengthens recruitment of corepressor proteins such as NCoR and HDAC3. This increases repression of target genes, including Bmal1 and other clock-controlled and metabolic genes. In rodent studies, such changes have been linked to altered lipid handling, glucose metabolism, and energy expenditure. The precise chain of events between receptor binding and whole-body effects remains an active area of research. Findings in animals do not automatically translate to humans.
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.
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.

Detection of SR9009 in biological samples usually employs liquid chromatography coupled with tandem mass spectrometry. This method can identify the parent compound and sometimes metabolites in urine or blood. Because exposure can be low and clearance may be rapid, sample timing and limits of detection matter. Laboratories validate assays for sensitivity and specificity. Results are interpreted alongside chain-of-custody and quality-control records. Urine is the common matrix for anti-doping analysis, while blood may be used in research settings.
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 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.
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 studied as an agonist of the nuclear receptors REV-ERBα and REV-ERBβ. It is not an approved medicine and has no established human therapeutic use. The compound appears in scientific literature as a tool for probing circadian and metabolic regulation. Online sellers often label it as a research chemical, sometimes using the nickname Stenabolic. Its chemical identity is distinct from selective androgen receptor modulators, stimulants, and peroxisome proliferator-activated receptor delta agonists. Researchers use it mainly in cell and animal experiments.
At the molecular level, SR9009 binds REV-ERBα and REV-ERBβ and alters their repressive activity on target genes. These nuclear receptors help regulate the circadian clock, lipid synthesis, glucose metabolism, and inflammatory pathways. By changing transcription, the compound can shift the timing or magnitude of downstream metabolic processes in model systems. It does not act through androgen receptors or adenosine receptors, which distinguishes it from several substances sold for athletic performance. Whether the same transcriptional changes occur in humans at tolerable exposures remains an open question because controlled human studies are lacking.
Preclinical reports describe effects on exercise endurance, mitochondrial content, and lipid profiles in rodents, but these findings come from specific experimental conditions. Many studies use high doses or delivery methods that may not translate directly to human use. SR9009 has been reported to have low oral bioavailability and a short half-life, which complicates interpretation of oral dosing studies. It is not established as safe or effective for any indication. Literature discussions often separate its pharmacological mechanism from unverified claims made in fitness and supplement markets.
A somatomammotroph or somatomammotrophic cell, also known as a somatolactotroph or somatolactotrophic cell, is a type of cell of the anterior pituitary gland that produces both somatotropin (growth hormone) and prolactin. Cells that secrete only somatotropin or only prolactin are known as somatotrophs and mammotrophs, respectively.
Copernicium is a synthetic chemical element; it has symbol Cn and atomic number 112. Its known isotopes are extremely radioactive, and have only been created in a laboratory. The most stable known isotope, copernicium-285, has a half-life of approximately 30 seconds. Copernicium was first created in February 1996 by the GSI Helmholtz Centre for Heavy Ion Research near Darmstadt, Germany. It was named after the astronomer Nicolaus Copernicus on his 537th anniversary. In the periodic table of the elements, copernicium is a d-block transactinide element and a group 12 element. During reactions with gold, it has been shown to be an extremely volatile element, so much so that it is possibly a gas or a volatile liquid at standard temperature and pressure. Copernicium is calculated to have several properties that differ from its lighter homologues in group 12, zinc, cadmium and mercury; due to relativistic effects, it may give up its 6d electrons instead of its 7s ones, and it may have more similarities to the noble gases such as radon rather than its group 12 homologues. Calculations indicate that copernicium may show the oxidation state +4, while mercury shows it in only one compound of disputed existence and zinc and cadmium do not show it at all. It has also been predicted to be more difficult to oxidize copernicium from its neutral state than the other group 12 elements. Predictions vary on whether solid copernicium would be a metal, semiconductor, or insulator. Copernicium is one of the heaviest elements whose chemical properties have been experimentally investigated.
== Diagnosis == The history of a preceding influenza-like infection followed by the typical symptoms of acute onset of symmetrical calf pain and gait problems together with an isolated finding of a high level of creatine kinase suggests the diagnosis of BACM. Myoglobinuria is rare and points to the possibility of the development of rhabdomyolysis and kidney failure. Guillain-Barré syndrome (GBS) is the main consideration in the differential diagnosis. It needs to be quickly excluded as early intervention in GBS is indicated. Other conditions under possible consideration are dermatomyositis, muscular dystrophy, juvenile idiopathic arthritis, transient synovitis of the hip, osteomyelitis, and myalgia. Few muscle biopsies have been conducted. Results may show normal findings or features of inflammation and necrosis.

== Business model == Juniper is identified as part of a vertically integrated healthcare model in the Australian telehealth sector. Its clinical consultations, prescribing and medication delivery are offered within a single online platform. This model has drawn regulatory attention over advertising practices and conflicts between commercial incentives and clinical decision-making. Regulators emphasise that prescribing decisions remain the responsibility of individual clinicians.
=== Integration of Biocon Biologics === On 6 December 2025, Biocon announced that it would fully integrate its biosimilars subsidiary Biocon Biologics Limited (BBL) as a wholly owned subsidiary, in a corporate action that valued BBL at US$5.5 billion and marked a pivot away from a previously planned initial public offering (IPO) of the biosimilars business. The company said the integration would simplify the group's corporate structure, remove the holding-company discount that had weighed on its valuation, and combine its generics and biosimilars operations into a single listed entity focused on diabetes, oncology and immunology. Under the plan, Biocon acquired the minority stakes held by Serum Institute Life Sciences, Tata Capital Growth Fund II and Activ Pine LLP through a share swap of 70.28 Biocon shares for every 100 BBL shares, priced at ₹405.78 per Biocon share. It also bought out the residual stake held by Mylan Inc. (Viatris) for US$815 million, comprising US$400 million in cash and US$415 million via a share swap, with the swap ratios based on independent valuations by EY. To fund the cash component payable to Viatris, Biocon raised approximately ₹4,150 crore (about US$460 million) through a qualified institutional placement (QIP) completed on 14 January 2026. The integration was completed by 31 March 2026, making Biocon Biologics a wholly owned subsidiary of Biocon Limited and creating a unified entity spanning biosimilars, insulins, generics and peptides. The leadership transition that followed is described under Corporate governance.
=== Occupational diseases === Men are more likely to be employed in positions with higher exposure to occupational health hazards. They account for two-thirds of occupational diseases leading to permanent disability. Deaths from occupational disease are over 80 times more common among men than women.
In December 2015, a norovirus outbreak at a Chipotle restaurant near Boston College sickened approximately 140 people, many of them students. The Boston Public Health Commission traced the outbreak to a sick employee who had been allowed to work. In response to the 2015 outbreaks, Chipotle closed all locations on February 8, 2016, for an all-staff food safety meeting and hired a new head of food safety who instituted enhanced protocols including more frequent handwashing, produce sanitation procedures, and Pascalization to pre-treat ingredients.
