01Mechanism of Action

Parameter

5-Amino-1MQ

Oxytocin

Primary target

Nicotinamide N-methyltransferase (NNMT)Neelakantan 2018

Oxytocin receptors (OXTR) — hypothalamus, amygdala, hippocampus, ventral tegmental area

Pathway

NNMT inhibition → preserved cellular SAM + NAD⁺ → restored methylation balance + ↑ thermogenic gene expressionNeelakantan 2018

OXTR activation → Gq/11-coupled signaling → modulation of GABAergic, dopaminergic, serotonergic pathways → enhanced synaptic plasticity, neurogenesis, emotional regulation

Downstream effect

Reversal of HFD-induced obesity in murine models; improved metabolic profileNeelakantan 2018

Social bonding enhancement, trust behavior, gaze modulation, reciprocal eye contact, anti-inflammatory and antioxidant neuroprotection, reduced amygdala threat responsePaul 2026 Prinsen 2026 Yuan 2026

Feedback intact?

—

Yes — endogenous oxytocin-mediated feedback via central and peripheral OXTR pathways

Origin

Selective small-molecule inhibitor designed in academic medicinal chemistry programsNeelakantan 2018

Endogenous 9-amino-acid peptide synthesized in hypothalamic paraventricular and supraoptic nuclei, released from posterior pituitaryPaul 2026

05Administration Protocol

Parameter

5-Amino-1MQ

Oxytocin

1. Form

Oral capsule. No injection.

Administer 24–48 IU (typically 3–6 puffs per nostril) using nasal spray device. Patient should be seated, head tilted slightly forward. Avoid sniffing deeply; allow passive absorption.

2. Administration

Take with water, fasted preferred.

Administer 30–90 minutes before anticipated social interaction or cognitive assessment. Acute effects peak within 30–60 minutes.

3. Timing

Morning fasted.

Dilute oxytocin 10 units in 1000 mL isotonic saline. Initiate at 0.5–2 mU/min via infusion pump. Titrate every 30–60 minutes based on contraction pattern and fetal heart rate. Continuous electronic fetal monitoring required.

4. Storage

Room temp ≤25 °C, dry place.

Store at 2–8 °C (refrigerated). Do not freeze. Protect from light. Discard if solution is discolored or contains precipitate.

5. Caveat

Monitor B-vitamin status with chronic use.

Chronic administration protocols (4–12 weeks) documented in pediatric ASD populations. Daily or twice-daily intranasal administration. Safety profile in chronic use still under investigation.
