Description
Trofinetide is a stable analog of glycine-proline-glutamate (GPE), a naturally occurring IGF-1-derived neuropeptide. Engineered to improve pharmacokinetics, it offers enhanced anti-inflammatory, cytoprotective, and synaptic-supportive effects. It suppresses key inflammatory mediators (e.g., IL-1?, TNF-?, IFN-?), reduces neuroinflammation, and shows efficacy in Rett syndrome clinical models. As the first FDA-approved treatment for Rett syndrome, Trofinetide underscores its translational potential. For lab-scale studies, this product offers 99.90% purity and GMP-backed consistency.

Mechanism of Action & Research Applications
Trofinetide reduces neuroinflammation by blocking pro-inflammatory cytokines and enhances synaptic function. It’s used extensively in:
Rett syndrome research and preclinical modeling
Neuroprotective studies targeting inflammation and apoptosis
Brain injury models—ameliorates synaptic loss and neuronal damage
Its mechanistic profile and clinical relevance make Trofinetide a powerful research tool for developmental neurobiology and neuroinflammation studies.
Side Effects (For Research Context Only)
Clinical data indicate manageable side effects, with the most frequent being:
Diarrhea and vomiting, often dose-related
Improved tolerability with gradual dosing
These considerations are important for designing translational and long-term studies.
