Mechanism of Action
SR9009 is described as an agonist of the nuclear receptors REV-ERBα and REV-ERBβ. These receptors function as transcriptional regulators and participate in the molecular mechanisms that control circadian rhythms.
REV-ERB signaling is associated with several research areas, including:
- Circadian-clock regulation
- Metabolic gene expression
- Lipid metabolism
- Glucose-related pathways
- Inflammatory signaling
- Cellular energy regulation
- Mitochondrial function
- Nuclear-receptor biology
Reported research has described SR9009 as having half-maximal inhibitory concentration values of approximately 670 nM for REV-ERBα and 800 nM for REV-ERBβ in the cited receptor-dependent repressor assays. These values are assay-specific and should not be interpreted as clinical dosage information.
Research Applications
Circadian-Rhythm Research
SR9009 is used to investigate the molecular pathways involved in circadian-clock regulation. REV-ERB proteins are important components of the transcriptional feedback systems that help regulate biological timing.
Metabolic Signaling Research
Researchers may study SR9009 in connection with:
- Cellular energy metabolism
- Lipid-processing pathways
- Glucose-related signaling
- Mitochondrial activity
- Metabolic gene expression
- Nuclear-receptor interactions
Inflammation Research
SR9009 has been investigated in experimental models involving inflammatory signaling. These studies may examine changes in inflammatory mediators, immune-cell responses, and gene-expression pathways.
Autophagy Research
Some published studies have evaluated SR9009 in relation to autophagy and cellular stress pathways. Results may vary depending on the cell type, experimental conditions, and concentration used.
Cancer Biology Research
SR9009 has been investigated in preclinical cancer-related research, including studies of cellular metabolism, proliferation, apoptosis, and autophagy. These findings are experimental and do not establish a treatment or therapeutic application.
Nuclear-Receptor Research
SR9009 is useful as a research tool for examining REV-ERB-dependent transcription and comparing nuclear-receptor signaling pathways.
REV-ERBα and REV-ERBβ Activity
REV-ERBα and REV-ERBβ are nuclear receptors that act as transcriptional repressors. They contribute to the regulation of genes involved in circadian timing and metabolism.
SR9009 is commonly used to study:
- REV-ERB receptor activation
- Transcriptional repression
- Circadian gene networks
- Metabolic gene regulation
- Receptor-dependent cellular responses
The reported activity values for SR9009 differ between assay systems and research models. Therefore, researchers should rely on the experimental data and documentation associated with the specific batch and study rather than treating one activity value as universally applicable.
Cell-Based Research
SR9009 has been studied in cell-based systems designed to measure REV-ERB activity and downstream biological responses. Research may include:
- Reporter-gene assays
- Nuclear-receptor transactivation studies
- Gene-expression analysis
- Circadian-clock investigations
- Cellular metabolism experiments
- Autophagy-related assays
- Inflammatory-response studies
The activity of SR9009 can depend on the cell line, assay design, exposure conditions, receptor expression, and analytical method. Results from one model should not automatically be generalized to other cell types or organisms.
Solubility and Laboratory Handling
GLPBIO’s indexed information reports SR9009 solubility in DMSO at approximately 43.8 mg/mL or greater, although solubility values can vary by supplier, formulation, temperature, and batch. Other research suppliers report different solvent-specific values.
| Solvent | Reported Information |
|---|---|
| DMSO | Soluble; GLPBIO reports ≥43.8 mg/mL |
| Ethanol | Solubility reported by some suppliers |
| Water | Not considered a preferred solvent |
| DMF | Reported as a compatible organic solvent by some suppliers |
Laboratory personnel should consult the current product documentation before preparing any solution. The appropriate solvent and handling procedure must be selected according to the experimental design, chemical compatibility, and institutional safety requirements.
Storage and Stability
GLPBIO’s indexed product information recommends storing SR9009 at approximately −20°C. It also advises avoiding repeated freezing and thawing of prepared stock solutions.
| Material Form | General Storage Information |
|---|---|
| Powder | Store at approximately −20°C |
| DMSO Stock Solution | Follow the supplier’s batch-specific stability guidance |
| Repeated Freeze-Thaw Cycles | Avoid where possible |
