Molecular structure of Reta
Chemical Name: LY3437943, Synthetic peptide triple hormone receptor agonist
Molecular Formula: C233H364N56O77
Molecular Weight: 5312.8 g/mol
CAS Number: 2381089-83-2
Classification: Triple receptor agonist targeting glucagon like peptide 1 (GLP-1), glucose dependent insulinotropic polypeptide (GIP), and glucagon receptors
Reta is a synthetic peptide engineered as a novel triple glucagon hormone receptor agonist retatrutide. The molecular architecture consists of a single peptide chain conjugated to a fatty diacid moiety through acylation, which extends the half-life to approximately 6 days enabling convenient once-weekly administration for laboratory research purposes. This structural modification significantly improves pharmacokinetic properties and bioavailability compared to shorter-acting compounds.
Mechanism of action
Reta functions as a triple hormone receptor agonist with distinct potency profiles across three critical metabolic pathways. The compound demonstrates approximately 8.9 times greater potency than endogenous GIP at the human gip receptor, 0.4 times the potency of endogenous GLP-1 at GLP-1 receptors, and 0.3 times the potency of glucagon at glucagon receptors.
This engineered receptor agonist reta activates G-protein coupled receptors, initiating adenylate cyclase activation and increasing cyclic adenosine monophosphate (cAMP) levels. The resulting signaling cascades enhance insulin sensitivity, improve glycemic control, reduce food intake through appetite regulation, and increase energy expenditure through glucagon receptor agonism. The synergistic effects of multi-receptor targeting promote weight loss through both reduced caloric intake and enhanced fat burning mechanisms.
The glucagon receptor activation specifically distinguishes Reta from existing weight loss drugs by increasing metabolic rate and promoting substantial reductions in liver fat while maintaining glucose homeostasis through balanced GLP-1 and GIP effects.
Research Studies
Early clinical trials have shown great results for Reta in obesity and metabolic health. In phase 2 placebo controlled trials, Reta achieved mean weight loss of up to 24.2% at 48 weeks in overweight and obese adults, better than current obesity drugs.
| Study Phase | Duration | Population | Average Weight Loss / Key Outcomes |
|---|---|---|---|
| Phase 1 | Multiple ascending dose trial | Healthy volunteers | Safety/tolerability established; No serious adverse events at therapeutic doses |
| Phase 2 | 48 weeks | 338 obese adults | Up to 24.2% body weight reduction; Superior efficacy vs placebo group |
| Phase 3 | TRIUMPH program (ongoing) | Various populations | In progress; Obesity treatment and metabolic diseases |
The compound has dose dependent efficacy, lower starting dose protocols minimizes gastrointestinal adverse events while maintaining therapeutic benefit. Clinical proof of concept studies show Reta targets multiple pathways simultaneously, better than single receptor weight loss drugs.
Storage and Safety
Reta should be stored between 2°C to 8°C (36°F to 46°F) for laboratory research purposes. Store in original packaging protected from light and contamination. Do not freeze and do not expose to temperatures above 25°C as thermal degradation can affect research outcomes.
Safety profiles from early clinical trials show generally manageable tolerability. Common adverse events are gastrointestinal symptoms like nausea, vomiting and diarrhea which occur at treatment initiation and decrease over time. No serious hypoglycemia related risks have been reported in clinical studies, different from some metabolic treatments.
Proper reconstitution protocols and handling procedures are crucial for compound stability. Research applications should follow established guidelines for peptide handling and storage to ensure consistent results.
