1.MECHANISM OF ACTION

[D-Tyr¹¹]-Neurotensin exerts its biological effects through high-affinity binding to both NTS1 and NTS2 neurotensin receptors—G-protein-coupled receptors (GPCRs) widely expressed in the central nervous system (ventral midbrain, limbic system, spinal cord) and peripheral tissues. The D-Tyr substitution at position 11 is the core structural modification that enhances the peptide’s resistance to endogenous peptidases, prolonging its half-life and sustaining biological activity compared to native neurotensin, while maintaining high receptor selectivity.

2.PRODUCT INDICATIONS

NTS receptor research: Investigation of NTS1/NTS2 structure-function relationships, serving as a standard ligand for receptor activation assays, agonist/antagonist screening, and binding kinetic analysis.

Neuroscience research: Study of dopamine signaling, glutamatergic neurotransmission, and limbic system function, leveraging the analog’s enhanced stability for long-term neurophysiology assays.

Pharmacology research: Development and validation of NTS receptor-targeted therapeutics for neurological disorders, reward-related behaviors, and pain management.

3.CLINICAL EFFICACY OF PRODUCT

[D-Tyr¹¹]-Neurotensin is widely utilized in preclinical neuroscience research, with proven efficacy in in vitro and in vivo rodent models. In ventral midbrain neuronal cell assays, it exhibits potent NTS1/NTS2 activation, effectively modulating glutamatergic and dopaminergic neurotransmission with sustained activity due to its D-Tyr-enhanced metabolic stability—outperforming native neurotensin in long-duration experiments.
