01Mechanism of Action

Parameter
5-Amino-1MQ
Triptorelin
Primary target
Nicotinamide N-methyltransferase (NNMT)Neelakantan 2018
Pituitary GnRH receptorsUnknown 2012
Pathway
NNMT inhibition → preserved cellular SAM + NAD⁺ → restored methylation balance + ↑ thermogenic gene expressionNeelakantan 2018
GnRH receptor agonism → initial flare (LH/FSH spike) → receptor desensitization → sustained LH/FSH suppression
Downstream effect
Reversal of HFD-induced obesity in murine models; improved metabolic profileNeelakantan 2018
Castration-level suppression of testosterone (men) and estrogen (women) within 2–4 weeks post-flare
Feedback intact?
No — bypasses physiological pulsatility; continuous agonism produces paradoxical suppression
Origin
Selective small-molecule inhibitor designed in academic medicinal chemistry programsNeelakantan 2018
Synthetic decapeptide analogue of native GnRH with amino acid substitutions for enhanced receptor affinity and stability
Antibody development

Half-life
Hours (estimated; no human PK published)
1-month depot
3.75 mg IM
Most common formulation for prostate cancer.
3-month depot

6-month depot
22.5 mg IMYee 2025Chen 2024

Administration route
Intramuscular (IM) — gluteal or deltoid
Indication: Prostate cancer
Advanced (metastatic or locally advanced)
Androgen deprivation therapy (ADT) backbone.
Indication: Endometriosis
3.75 mg monthly
FDA-approved; typically 6-month course.
Indication: Central precocious puberty
Pediatric use (≥2 years)Jia 2025
Weight-based dosing per FDA label.
Duration (prostate cancer)
Continuous or intermittent ADT protocolsPreston 2024
Intermittent ADT may reduce side effects; cardiovascular risk similar to continuous.
Monitoring
Serum testosterone, PSA (prostate cancer), bone density, lipids, glucose

04Side Effects & Safety

Parameter
5-Amino-1MQ
Triptorelin
GI symptoms
Mild nausea (anecdotal)
Methylation disruption
Theoretical risk if NNMT is over-inhibited (B vitamin metabolism)
Long-term safety
Unknown — no human trials
Cancer risk
Unclear — NNMT also studied in oncology contexts
Pregnancy / OB
Avoid
Drug interactions
Theoretical with niacin / B-vitamin supplements
Initial flare symptoms
Bone pain, urinary obstruction, spinal cord compression (first 2 weeks)
Antiandrogen co-treatment (bicalutamide) mitigates flare in metastatic disease.
Cardiovascular events
MI, stroke, arrhythmia — GnRH agonists show higher CV risk vs antagonists in meta-analysesPatel 2025Preston 2024
Hot flashes
Very common (>60%); vasomotor instability
Bone loss / Osteoporosis
Accelerated bone mineral density decline; fracture risk ↑Friedrich 2025
Baseline DEXA scan recommended; bisphosphonates or denosumab may be indicated.
Metabolic syndrome
Weight gain, insulin resistance, dyslipidemia, diabetes risk
Sexual dysfunction
Erectile dysfunction, loss of libido (expected pharmacological effect)Jia 2025
Injection site reactions
Pain, erythema, sterile abscess (rare with depot formulations)
Gynecomastia / Breast tenderness
Common (10–20%); peripheral aromatization of residual androgens
Fatigue / Mood changes
Anemia, depression, cognitive changes reported in long-term ADT
Hepatotoxicity
Transient transaminase elevations; clinically apparent liver injury rare
Racial differences (ADT)
Black veterans show higher CV event rates vs White veterans on GnRH agonists
Absolute Contraindications
5-Amino-1MQ
  • ·Pregnancy / breastfeeding
  • ·Active malignancy
Triptorelin
  • ·Hypersensitivity to triptorelin, GnRH, or GnRH agonist analogues
  • ·Pregnancy (Category X)
Relative Contraindications
5-Amino-1MQ
  • ·Methylation-sensitive conditions (MTHFR mutation)
  • ·Concurrent niacin / NAD+ precursor supplementation (theoretical interference)
Triptorelin
  • ·Active cardiovascular disease — consider GnRH antagonist alternative
  • ·Metastatic vertebral disease with spinal cord compression risk (flare hazard)
  • ·Severe urinary obstruction — may worsen during flare
  • ·Osteoporosis or high fracture risk (requires bone-protective therapy)

05Administration Protocol

Parameter
5-Amino-1MQ
Triptorelin
1. Form
Oral capsule. No injection.
Choose 1-month (3.75 mg), 3-month (11.25 mg), or 6-month (22.5 mg) depot based on adherence needs and clinical context. 6-month formulation shows improved real-world adherence in Asia-Pacific cohorts.
2. Administration
Take with water, fasted preferred.
Intramuscular — gluteal or deltoid muscle. Use 21–23G needle. Aspirate to confirm non-vascular placement. Rotate sites with repeat injections.
3. Timing
Morning fasted.
For metastatic prostate cancer: co-administer antiandrogen (e.g., bicalutamide 50 mg daily) starting 1 week before first injection and continuing 2–4 weeks to prevent tumor flare.
4. Storage
Room temp ≤25 °C, dry place.
Baseline: testosterone, PSA, bone density (DEXA), lipids, glucose. Follow-up: testosterone at 4 weeks (confirm <50 ng/dL castration), PSA monthly × 3, then quarterly. Annual DEXA for bone loss.
5. Caveat
Monitor B-vitamin status with chronic use.
Store vials at room temperature (20–25 °C), protect from light. Do not freeze. Reconstituted suspension should be used immediately.
6. Intermittent ADT protocol (optional)
Some protocols use on-treatment periods (9–12 months) alternating with off-treatment intervals until PSA rises. Cardiovascular risk appears similar to continuous ADT.
