What is SLU-PP-332?

SLU-PP-332 is a synthetic small-molecule agonist of estrogen-related receptors (ERRs), specifically ERR-alpha, ERR-beta, and ERR-gamma. These orphan nuclear receptors regulate the transcription of genes involved in mitochondrial biogenesis, oxidative phosphorylation, and fatty acid metabolism. Research from the Bhatt laboratory at Saint Louis University (published in ACS Chemical Biology, 2023) demonstrated that SLU-PP-332 administration in mouse models increased exercise endurance and fatigue resistance without physical training, earning it attention as a potential exercise mimetic compound. The mechanism involves upregulating PGC-1alpha-dependent gene networks that enhance mitochondrial density and oxidative capacity in skeletal muscle. In ischemic stroke models, ERR activation by SLU-PP-332 has shown neuroprotective effects by preserving mitochondrial membrane integrity and reducing reactive oxygen species production (Willy et al., published in Cell Chemical Biology). Compared to other exercise mimetics such as AICAR (AMPK activator) or GW501516 (PPAR-delta agonist), SLU-PP-332 targets a distinct upstream transcriptional pathway that coordinately activates multiple metabolic gene programs rather than a single signaling cascade. Research also suggests potential applications in chronic fatigue and neurodegenerative conditions where mitochondrial dysfunction is implicated. Store lyophilized powder at -20C in a desiccated environment; reconstitute in DMSO or appropriate vehicle per protocol specifications. SLU-PP-332 is investigated by exercise physiology researchers, neuroscience departments studying metabolic neuroprotection, and pharmacology labs exploring nuclear receptor biology.

SLU-PP-332 Research Applications

In published and preclinical research, SLU-PP-332 has been studied across the following areas:

Mitochondrial and chronic fatigue therapies
Weight management pathways

SLU-PP-332 in Research: Reconstitution & Study Concentrations

SLU-PP-332 is supplied as a lyophilized powder. For laboratory research it is reconstituted with bacteriostatic or sterile water; the solvent volume sets the working concentration. Published studies select concentrations specific to the assay or model system — there is no human dose, as SLU-PP-332 is not approved for human use. Researchers should reference the primary literature for the model in question and document the exact lot COA.

Worked example: a 5mg vial reconstituted with 2 mL of bacteriostatic water yields 2.50 mg/mL.

SLU-PP-332 — Frequently Asked Questions

What is SLU-PP-332 and how does it work?

SLU-PP-332 is a synthetic compound that functions as an agonist of estrogen-related receptors (ERRs), particularly ERR-alpha, ERR-beta, and ERR-gamma. These nuclear receptors regulate genes involved in mitochondrial biogenesis, oxidative phosphorylation, and fatty acid metabolism. In preclinical studies, SLU-PP-332 has been observed to enhance exercise-related gene expression in skeletal muscle without actual physical activity.

What research has been done on SLU-PP-332?

Research from the Bhatt Lab at Saint Louis University (published in Journal of Pharmacology and Experimental Therapeutics) demonstrated that SLU-PP-332 activated ERR-dependent transcriptional programs in muscle tissue. Mouse studies showed increased running endurance and improved resistance to diet-induced obesity. Additional research has explored its neuroprotective potential in ischemic stroke models and chronic fatigue conditions.

How does SLU-PP-332 compare to GW501516 (Cardarine)?

While both compounds have been studied as exercise mimetics, they act through different nuclear receptor pathways. GW501516 targets PPAR-delta, whereas SLU-PP-332 activates ERR-alpha/beta/gamma receptors. ERRs sit upstream of many mitochondrial genes, giving SLU-PP-332 a broader metabolic profile in preclinical models. GW501516 has raised safety concerns in long-term rodent studies that have not been observed with SLU-PP-332.

What is the recommended reconstitution protocol for SLU-PP-332?

For this 5mg vial, reconstitute with 1mL of bacteriostatic water to yield a concentration of 5.0mg/mL. Inject the water slowly along the inner wall of the vial — do not shake or agitate. Allow the lyophilized powder to dissolve fully (typically 2-5 minutes). Store reconstituted solution at 2-8°C and use within 30 days.

Is SLU-PP-332 legal to buy for research?

SLU-PP-332 is sold in the United States as a research chemical for laboratory and in-vitro use only. It is not approved by the FDA for human use and is not sold for human consumption. Researchers are responsible for compliance with all applicable federal, state, and institutional regulations.

How is SLU-PP-332 reconstituted for research use?

SLU-PP-332 ships as a lyophilized (freeze-dried) powder and is reconstituted with bacteriostatic or sterile water before use in research. The volume of solvent added determines the working concentration — use the Elyte reconstitution calculator to derive the exact concentration for a given vial size and solvent volume.

Does SLU-PP-332 come with a Certificate of Analysis?

Yes. Every batch of SLU-PP-332 from Elyte Peptides ships with a third-party Certificate of Analysis (COA) documenting identity and HPLC purity (≥98%), so research results can be traced to a verified lot.
