SLU-PP-332- Summary
- Oxytocin is a 9-amino acid neuropeptide produced in the hypothalamus with diverse roles in social bonding, trust, stress reduction, and sexual function. Exogenous administration is used therapeutically to improve social cognition, reduce anxiety, and enhance intimacy.
- SLU-PP-332 is a small molecule exercise mimetic that activates estrogen-related receptors ERRalpha and ERRdelta (ERRa/d), transcription factors that drive oxidative metabolism programs. In animal studies it significantly enhanced endurance capacity and metabolic fitness without exercise, mimicking many of the cardiovascular and metabolic adaptations of aerobic training.
- Half-Life
- ~3–5 minutes (IV); ~30–60 minutes (intranasal, CNS effects persist longer)
- Not established in humans; rodent pharmacokinetics suggest hours
- Admin Route
- Intranasal, SubQ, IV
- Oral (research), Subcutaneous (research)
