1.MECHANISM OF ACTION

Neurotensin (8-13), N-Acetyl exerts its biological effects by binding with high affinity to neurotensin receptors NTSR1 and NTSR2, primarily coupling to Gq/11 proteins to activate phospholipase C and increase intracellular calcium mobilization. This signaling cascade modulates neuronal excitability, dopamine transmission, and nociceptive processing in the central nervous system, while also influencing gastrointestinal motility and secretion in peripheral tissues. The N-terminal acetylation enhances peptide stability by reducing enzymatic degradation, prolonging its half-life and pharmacological activity in experimental systems without significantly altering receptor selectivity.

2.PRODUCT INDICATIONS

This peptide is indicated for research applications focused on neurotensin receptor signaling, central nervous system function, and gastrointestinal physiology. It is utilized in in vitroassays with NTSR-expressing cells to study receptor binding, calcium flux, and intracellular signaling pathways. In in vivostudies, it is administered to investigate neurotensin-mediated effects on pain perception, thermoregulation, dopamine transmission, and gut motility in preclinical models. The product also serves as a reference standard for receptor autoradiography, immunohistochemistry, and functional assays to explore the role of neurotensin in neurological disorders, pain conditions, and gastrointestinal diseases.

3.CLINICAL EFFICACY OF PRODUCT

Neurotensin (8-13), N-Acetyl has no clinical efficacy or safety profile, as it is strictly a research reagent for preclinical investigations. The peptide has not undergone clinical trials, regulatory evaluation, or safety assessment for diagnostic or therapeutic use in humans. While preclinical studies demonstrate its potent analgesic, hypothermic, and dopamine-modulating effects, these findings remain exploratory and have not been translated into validated clinical interventions. Any potential therapeutic applications would require the development of stable analogs or formulations with comprehensive pharmacokinetic and safety evaluations.
