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.
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.
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.

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.
SR9009 is frequently discussed in fitness and research-chemical contexts, yet it has no approved medical indication. Regulatory agencies have not authorized it for human use, and it is not a standard prescription drug. Some sports organizations list it as a prohibited substance because of its potential performance-enhancing properties. Published human data are sparse, so claims about its effects in people often rely on animal models or anecdotal reports. Quality and identity of online materials can vary widely.
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 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.
Identity and purity of SR9009 samples are usually checked with chromatographic and spectrometric methods. High-performance liquid chromatography can separate the compound from related impurities, while mass spectrometry provides molecular mass confirmation. Nuclear magnetic resonance spectroscopy may be used for structural verification in research settings. No single method proves biological activity, and certificates of analysis should be reviewed alongside raw data. Independent testing is often needed because online products vary widely.

29 July – Laura Mackenzie, whose offer of a job with Police Scotland was withdrawn when it emerged she had been prescribed antidepressants, launches legal action against the force. The offer was withdrawn after her medical history came to light during a health examination prior to starting the job, and because Police Scotland requires any recruits to be clear of antidepressant medication for at least two years. 31 July Media outlets, including BBC News, report that a medical student has been expelled from the University of Dundee after filming the dissection of a human body and posting the footage online. The 2023 Rutherglen and Hamilton West recall petition closes. A by-election is triggered after the petition to remove Margaret Ferrier from office is signed by 11,896 of the 81,124 eligible constituents, passing the required 10% threshold.

== Release of GST-A1 as an indication of cellular necrosis == Increases in serum and urinary GST-A1 have been found in association with hepatocyte and renal proximal tubular necrosis respectively, and have potential for monitoring injury to these tissues.
== History == Coiled-coil research began in 1953 when Dr. Francis Crick first reported on the theory behind the packing formation of α-helices in fibrous proteins at the time, which he proposed to consist of alpha helices composed of heptad repeats, or seven-residue repeats (a-b-c-d-e-f-g), whereby 2 or more alpha helices twist around each other similar to the strands of a rope. In 1972, Dr. Robert Hodges and his colleagues confirmed Dr. Crick's hypothesis upon sequencing tropomyosin, further discovering that the heptad repeat consists of two hydrophobic residues at the a and d positions, which stabilize coiled coils and are their basis for formation. This confirmation formed the basis for designing engineered coiled-coil proteins to further investigate and better understand coiled-coil interactions, structures, functions, oligomerization, and other properties. Later in 1991, Dr. O'Shea and colleagues obtained the first high-resolution image of a two-stranded coiled-coil at a resolution of 1.8Å. Dr. Hodges was the first to suggest the use of coiled coils in a drug delivery system in 1996 when he proposed a two-stage targeting and delivery system based on heterodimerization, whereby a drug would be conjugated to chain 1 and an antibody would be conjugated to chain 2, such that chains 1 and 2 would form a heterodimeric coiled coil.
== Applications == Currently, it is used industrially to verify, with a high throughput, the concentrations of brominated flame retardants (BFR) in plastics in compliance with the European Union's RoHS (Restriction of Hazardous Substances) regulation in place since 2006. The banned molecules include PBB and PBDE, whose concentration should not exceed 0.1% w/w. IAMS has also been used to analyze diesel exhaust particles, in ceramic processing, and in critical silicon etching during semiconductor manufacturing.

=== Role in wound healing === The role of endothelial progenitor cells in wound healing remains unclear. Blood vessels have been seen entering ischemic tissue in a process driven by mechanically forced ingress of existing capillaries into the avascular region, and importantly, instead of through sprouting angiogenesis. These observations contradict sprouting angiogenesis driven by EPCs. Taken together with the inability to find bone-marrow derived endothelium in new vasculature, there is now little material support for postnatal vasculogenesis. Instead, angiogenesis is likely driven by a process of physical force.
== Clinical significance == Haptotaxis plays a major role in the efficient healing of wounds. For example, when corneal integrity is compromised, epithelial cells quickly cover the damaged area by proliferation and migration (haptotaxis). In the corneal stroma, keratocytes within the wounded area undergo apoptosis, leaving the stroma devoid of cells that must be replaced. Keratocytes surrounding the wounded area proliferate and become fibroblasts that migrate to fill the wounded area. This creates a healthy environment with myofibroblasts and extracellular matrix. This is known as light backscattering or subepithial haze. When there is injury to an epithelial cell heptotaxis occurs, which is highly influenced by the cell's velocity, which is in turn influenced by direction of cell motility. Cells migrate easily and quickly in packs, so when one cell moves the rest follow in response to the gradient and initial cell movement. Mechanical effects like the buildup of tensile forces may play an important role for both division as well as motility of cells in tissue.
==== Prophecies and statements ==== In 2013, Bakker wrote Time Has Come: How to Prepare Now for Epic Events Ahead about end-time events. Bakker has changed his views on prosperity theology. In his 1980 book Eight Keys to Success, he stated, "God wants you to be happy, God wants you to be rich, God wants you to prosper." In his 1996 book, I Was Wrong, he admitted that the first time he actually read the Bible all the way through was in prison. Bakker also wrote that he realized that he had taken passages out of context and used them as prooftexts to support his prosperity theology. Bakker's revived show features a number of ministers who bill themselves as "prophets". He now says that "PTL" stands for "Prophets Talking Loud". In an October 2017 video, Bakker said that "God will punish those" who ridicule him; he has said that Hurricane Harvey was a judgment of God, and he blamed Hurricane Matthew on then-President Barack Obama. Bakker predicted that if then-President Donald Trump was impeached, Christians would begin a Second American Civil War. He compared the 2017 Washington train derailment to the sinking of the RMS Titanic and stated the Amtrak train derailment was a warning from God. He also claimed that he predicted the September 11 attacks of 2001, stating that he "saw 9/11 in 1999 before New Year's Eve" and that there would "be terrorism" and bombings in New York City and Washington, D.C. A few days after the Stoneman Douglas High School shooting, he stated that "God came to [him] in a dream...

SR9009 is a synthetic REV-ERB agonist used in laboratory research. It is not an approved drug, and its effects in humans are not well characterized. It is often sold as a research chemical under the name Stenabolic.
No. SR9009 targets the nuclear receptors REV-ERBα and REV-ERBβ, not the androgen receptor. This mechanism differs from selective androgen receptor modulators and from exercise mimetics that act on PPARδ.
Published evidence is mainly preclinical, using cell cultures and animal models. Controlled human trials are not well documented in the public literature. Claims about human performance or health effects therefore remain unsupported by robust clinical data.
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.
