Tesofensine — Triple Monoamine Reuptake Inhibitor (Dopamine/Norepinephrine/Serotonin)

Tesofensine is a potent small-molecule inhibitor of the dopamine, norepinephrine and serotonin transporters (DAT, NET, SERT). Originally developed for neurological disorders, it demonstrated significant weight-loss and metabolic effects in obese human and animal studies.

Identifiers
  • CAS No.: 195875-84-4 [oai_citation:1‡Wikipedia](https://en.wikipedia.org/wiki/Tesofensine?utm_source=chatgpt.com)
  • PubChem CID: 11370864 [oai_citation:2‡Wikipedia](https://en.wikipedia.org/wiki/Tesofensine?utm_source=chatgpt.com)
  • Mechanism class: Triple monoamine reuptake inhibitor (TMI) — DAT, NET, SERT [oai_citation:3‡PubMed](https://pubmed.ncbi.nlm.nih.gov/24239329/?utm_source=chatgpt.com)
  • Approx half-life: ~220 hours (≈9 days) reported in humans; main metabolite ~374 hours. [oai_citation:4‡Wikipedia](https://en.wikipedia.org/wiki/Tesofensine?utm_source=chatgpt.com)
Mechanism (Plain English)
  • By blocking the reuptake of dopamine, norepinephrine and serotonin, Tesofensine increases levels of these neurotransmitters in the brain. [oai_citation:5‡DrugBank](https://go.drugbank.com/drugs/DB06156?utm_source=chatgpt.com)
  • This enhanced signaling affects appetite centres (especially in the hypothalamus), leading to reduced food intake (hypophagia) and increased satiety. [oai_citation:6‡PMC](https://pmc.ncbi.nlm.nih.gov/articles/PMC3055463/?utm_source=chatgpt.com)
  • It also appears to modulate energy-expenditure pathways (via norepinephrine) and feeding-centres (via lateral hypothalamic GABAergic neuron suppression). [oai_citation:7‡PMC](https://pmc.ncbi.nlm.nih.gov/articles/PMC11042726/?utm_source=chatgpt.com)
Why Researchers Use It
  • To study central appetite/hunger regulation mechanisms via monoaminergic pathways.
  • To explore metabolic adaptation after weight loss and energy-balance regulation.
  • As a comparative tool versus other appetite-suppression or weight-loss agents (e.g., GLP-1 agonists, stimulant analogues).

Key Study Themes — What’s Tested, What Changed, Why It Matters

Diet-Induced Obese Rats: Hypophagia & Weight Loss
  • What was tested: Rats fed high-fat diet given Tesofensine (0.5-3.0 mg/kg, s.c. for 16 days) and food intake, weight change measured. [oai_citation:8‡PMC](https://pmc.ncbi.nlm.nih.gov/articles/PMC3055463/?utm_source=chatgpt.com)
  • What changed: Marked decline in food intake (ED₅₀ ~1.3 mg/kg), significant weight loss vs vehicle. [oai_citation:9‡PMC](https://pmc.ncbi.nlm.nih.gov/articles/PMC3055463/?utm_source=chatgpt.com)
  • Why it matters: Demonstrates mechanism of reduced intake + neural-circuit involvement in feeding. [oai_citation:10‡PMC](https://pmc.ncbi.nlm.nih.gov/articles/PMC3055463/?utm_source=chatgpt.com)
Human Obesity Trial (Phase II) – Body-Weight Loss
  • What was tested: Obese participants given Tesofensine (0.25 mg, 0.5 mg or 1 mg daily) + diet/exercise for 6 months. [oai_citation:11‡Wikipedia](https://en.wikipedia.org/wiki/Tesofensine?utm_source=chatgpt.com)
  • What changed: Average weight loss ~6.7 kg (0.25 mg), ~11.3 kg (0.5 mg), ~12.8 kg (1 mg) over 6 months; placebo ~2.2 kg. [oai_citation:12‡Wikipedia](https://en.wikipedia.org/wiki/Tesofensine?utm_source=chatgpt.com)
  • Why it matters: Shows potent appetite/weight outcome compared to older agents—valuable translational data.

Potential Research Applications

Appetite & Hunger Regulation

  • Hypothalamic circuits, feeding behaviour, GABAergic inhibition in the lateral hypothalamus. [oai_citation:14‡PMC](https://pmc.ncbi.nlm.nih.gov/articles/PMC11042726/?utm_source=chatgpt.com)

Obesity / Metabolic Adaptation Models

  • Energy-balance adaptation, post-weight-loss rebound, diet-resistance models. [oai_citation:15‡PMC](https://pmc.ncbi.nlm.nih.gov/articles/PMC11042726/?utm_source=chatgpt.com)

Monoaminergic Neuropharmacology

  • DAT/NET/SERT occupancy studies; compare with stimulant / antidepressant models. [oai_citation:16‡PubMed](https://pubmed.ncbi.nlm.nih.gov/24239329/?utm_source=chatgpt.com)

Synergistic / Comparator Agents

GLP-1 Agonists

  • Why compare/partner: Alternative central appetite/hormone signalling; useful to compare mode of action (monoamine vs gut-brain).

Peptides: MOTS-c, CJC-1295/Ipamorelin

  • Why compare: While Tesofensine targets central monoamines and appetite, peptide blends target metabolic/mitochondrial or GH/IGF axes—combined designs may dissect multiple layers of weight/regulation biology.

Design Notes

  • Include baseline hunger/appetite questionnaires, neurotransmitter marker panels (if possible), diet/exercise control arms.
  • Track cardiovascular parameters closely—monoamine modulators often increase HR/BP. [oai_citation:17‡Wikipedia](https://en.wikipedia.org/wiki/Tesofensine?utm_source=chatgpt.com)

Known Concerns (Context)

  • Cardiovascular effects:
  • Stimulant-like risks:
  • Regulatory status:
  • Monoamine modulation confounds:

Specifications & Handling

  • Form: Oral small-molecule compound (lot-coded) — confirm salt/chemical form.
  • Purity: Research-grade specification (HPLC/MS, ≥98%).
  • Storage: Manufacturer recommended; typically cool, dry conditions; protect from light/moisture.
  • In use: Dose and vehicle must be clearly documented; in vivo rodent dosing vs human research differs—specify model and route.
