1.MECHANISM OF ACTION

The biological effects of [D-Tyr²⁷,³⁶, D-Thr³²]-NPY (27-36), rat are mediated through high-affinity and selective binding to neuropeptide Y Y1 receptors—G-protein-coupled receptors (GPCRs) expressed in the rat hypothalamus, vascular smooth muscle, and peripheral metabolic tissues. The D-amino acid substitutions (D-Tyr²⁷,³⁶ and D-Thr³²) alter the peptide’s conformational structure, significantly improving resistance to endogenous peptidases and prolonging its half-life in rat in vitro and in vivo models, compared to native NPY fragments.

2.PRODUCT INDICATIONS

NPY Y1 receptor research: Investigation of Y1 receptor structure-function relationships in rat models, serving as a standard ligand for activation assays, agonist/antagonist screening, and selectivity validation.

Metabolic research: Utilization as a Human metabolic research peptide to study Y1 receptor-mediated appetite regulation, energy metabolism, and obesity-related pathways in rat models for translational applications

Neuroscience research: Study of Y1 receptor signaling in the rat hypothalamus, focusing on stress response, anxiety, and neuronal excitability linked to metabolic regulation.

3.CLINICAL EFFICACY OF PRODUCT

[D-Tyr²⁷,³⁶, D-Thr³²]-NPY (27-36), rat (CAS 163887-48-7) is widely used in preclinical rat models, with proven efficacy as a Human metabolic research peptide. In rat hypothalamic cell assays and in vivo studies, it exhibits potent and selective Y1 receptor activation, effectively modulating appetite and energy metabolism with sustained activity due to its enhanced stability—outperforming native NPY fragments.
