Dynorphin B (1-9) CAS NO.126050-26-8
<p>Dynorphin B (1-9) is an endogenous N-terminal neuropeptide fragment that serves as a potent and selective agonist for the kappa-opioid receptor (KOR). It features the core opioid sequence (YGGFL) followed by key residues (RRQF) that enhance its receptor affinity and stability. This peptide is widely used as a critical pharmacological tool in neuroscience research to study pain pathways, stress responses, and addi…

1.MECHANISM OF ACTION
The peptide exerts its effects by selectively binding to the kappa-opioid receptor (KOR), a Gi/o protein-coupled receptor. This binding inhibits adenylate cyclase, reducing intracellular cAMP levels, and modulates ion channel activity (inhibiting Ca²⁺ channels and activating K⁺ channels), leading to neuronal hyperpolarization. The result is a presynaptic inhibition of neurotransmitter release (e.g., glutamate, dopamine), which underlies its physiological effects on analgesia and mood regulation.
2.PRODUCT INDICATIONS
Dynorphin B (1-9) is indicated for preclinical research applications focused on the central nervous system. It is primarily used in studies investigating neuropathic pain, stress-induced behaviors, depression, and drug addiction. Researchers utilize this peptide to explore KOR's role in modulating the reward pathway and to develop novel non-addictive analgesic and anti-addiction therapies, making it essential for neuropharmacology and psychiatric disorder research.
3.CLINICAL EFFICACY OF PRODUCT
In experimental models, Dynorphin B (1-9) demonstrates significant KOR-mediated analgesic efficacy in chronic pain and neuropathic pain paradigms. It also shows modulatory effects on affective behaviors, reducing stress responses and drug-seeking behavior in addiction models. However, its efficacy is dose-dependent, as high concentrations can induce dysphoric or aversive effects, highlighting its utility in studying the complex biphasic nature of the dynorphin/KOR system.
