1.MECHANISM OF ACTION

Dual Receptor Binding: Binds to galanin receptors (GALR1/2/3, Ki: 0.5–5 nM) and neuropeptide Y receptors (Y1/Y2/Y5, Ki: 1–10 nM), modulating overlapping signaling pathways (e.g., cAMP inhibition, Ca²⁺ flux).

Neurotransmitter Regulation: Inhibits acetylcholine release in the hippocampus (galanin activity) and enhances GABAergic transmission in the hypothalamus (neuropeptide Y activity), balancing synaptic plasticity.

Appetite/Stress Crosstalk: Suppresses orexigenic NPY/AgRP signals and activates anorexigenic POMC neurons via Y1/Y5 receptors, while galanin-mediated GALR1 activation reduces stress-induced corticosterone release.

2.PRODUCT INDICATIONS

Neuroscience Research: Studying receptor crosstalk in depression, obesity, and epilepsy, where both galanin and NPY systems are dysregulated.

Multi-Target Drug Development: Screening dual-action agonists/antagonists for treating metabolic disorders (e.g., obesity) and neuropsychiatric conditions (e.g., anxiety).

Behavioral Studies: Investigating feeding behavior, pain perception, and stress responses in rodent models using tagged or fluorescently labeled variants.

3.CLINICAL EFFICACY OF PRODUCT

Reduces food intake by 40–60% in diet-induced obese mice (dual Y1/Y5 and GALR1 activation).

Therapeutic Potential: Early-stage studies suggest M32 analogs may outperform single-target peptides in managing comorbid obesity and depression.
