Overview

SLU-PP-332 is a synthetic small molecule pan-agonist of the estrogen-related receptor (ERR) family — specifically ERRα, ERRβ, and ERRγ. The short version: people usually care about it for exercise mimetic, err-alpha agonist, endurance research, but the strength of the evidence depends heavily on indication and study type.

SLU-PP-332 is a synthetic small molecule pan-agonist of the estrogen-related receptor (ERR) family — specifically ERRα, ERRβ, and ERRγ. Developed at Washington University in St. Louis (hence 'SLU'), it is classified as an 'exercise mimetic' — a compound that activates the same genetic programs triggered by aerobic exercise without requiring physical exertion.

> SLU-PP-332 is a pre-clinical research compound. It has NOT been tested in humans. All data is from mouse/cell studies. No human safety or dosing data exists.

What the evidence says

Animal

SLU-PP-332 currently shows 0 registered trials from ClinicalTrials.gov, 0 PubMed trial publications (0 RCT-tagged), and 10 PubMed references matching the stored source query. Treat PubMed references as literature surface area, not a count of clinical trials.

Known vs uncertain

Known signals

  • 0 registered trials are tracked from ClinicalTrials.gov intervention records.
  • 0 PubMed clinical-trial publications are indexed.
  • 0 PubMed randomized controlled trial publications are indexed.
  • 10 PubMed references are tracked separately from trial counts and can include animal, in-vitro, review, mechanism, or clinical records.

Open questions

  • Evidence strength may vary by indication, route, formulation, and population.
  • Public anecdotes can highlight interest or concern but do not establish clinical efficacy.
  • Regulatory status and compounding access can change independently from the research literature.

Mechanism of Action

SLU-PP-332 binds to ERR nuclear receptors (EC50: ERRα = 98 nM, ERRβ = 230 nM, ERRγ = 430 nM in cell-based assays).

Key Research Benefits

Enhanced exercise endurance: Mice treated with SLU-PP-332 ran ~70% longer and ~45% farther on treadmill tests (Xia et al., 2023, ACS Chemical Biology).
Muscle fiber type conversion: Increased proportion of slow-twitch oxidative (Type I) fibers in skeletal muscle, mimicking endurance training adaptations.
Metabolic syndrome improvement: In obese mice, SLU-PP-332 alleviated metabolic syndrome markers — reduced body weight, improved fatty acid oxidation, and enhanced mitochondrial function (Wang et al., 2024, J Med Chem).
Anti-aging potential: ERR activation counteracts mitochondrial dysfunction associated with aging. A 2025 pilot study (Frontiers in Physiology) explored ERR agonists for age-related muscle atrophy.
Cardioprotective: ERR agonism has shown benefits in heart failure models by improving cardiac mitochondrial function.

Anecdotes & Sentiment

Public discussion, not clinical evidence

This section summarizes what people are talking about in public sources. It can be useful for spotting questions, hype cycles, and recurring concerns, but it is separate from the evidence sections above.

No curated public-discussion themes are live for SLU-PP-332 yet.

Side Effects & Safety

> No human safety data exists.

> No human safety data exists. All side effect information is from animal models. Using this compound carries unknown risks.

Animal studies: No significant adverse effects were reported in published mouse studies at the doses tested. However, these were short-duration studies.
Theoretical concerns: ERR receptors are expressed in multiple tissues (heart, liver, kidney, brain). Non-selective pan-ERR activation could have unpredictable effects on these organs.
Estrogen receptor concern: Despite the name, ERRs are 'estrogen-related' but do not bind estrogen. No estrogenic activity has been observed.
Long-term safety: Completely unknown. Chronic ERR activation effects on muscle remodeling, cardiac tissue, and metabolism have not been studied.
