[D-Arg6] – Dynorphin A (1 – 13), porcine CAS NO.75921-87-8

[D-Arg⁶]-Dynorphin A (1-13), porcine is a strategically engineered analog of the endogenous neuropeptide, where the substitution of the 6th amino acid with a D-arginine confers exceptional resistance to enzymatic degradation. This modification significantly extends its metabolic half-life in research settings while retaining high affinity and selectivity for the kappa-opioid receptor (KOR). It serves as a potent and stable tool peptide for researchers investigating pain pathways, addiction mechanisms, and neuropsychiatric disorders, offering superior in vivo stability compared to the native peptide for more reliable experimental outcomes.

1.MECHANISM OF ACTION

This peptide functions as a highly selective kappa-opioid receptor (KOR) agonist, binding preferentially to KOR with minimal cross-reactivity to mu or delta opioid receptors. Upon binding, it activates the Gi/o protein-coupled pathway, leading to the inhibition of adenylate cyclase and a reduction in intracellular cAMP levels. This action modulates neuronal excitability by inhibiting voltage-gated calcium channels and promoting potassium efflux, resulting in the suppression of neurotransmitter release and the dampening of pain signal transmission within the central nervous system.

2.PRODUCT INDICATIONS

[D-Arg⁶]-Dynorphin A (1-13) is indicated for preclinical research focused on the kappa-opioid receptor system. It is widely used in studies of neuropathic and inflammatory pain models, addiction and reward pathways, as well as stress-related behaviors such as depression and anxiety. The peptide is particularly valuable for researchers seeking to develop non-addictive analgesic alternatives, as KOR activation produces analgesia without the typical mu-opioid receptor-associated risks of respiratory depression and physical dependence.

3.CLINICAL EFFICACY OF PRODUCT

In experimental models, this analog demonstrates potent and prolonged analgesic effects in both acute and chronic pain paradigms due to its enhanced stability. It effectively reduces pain-related behaviors in rodent models of nerve injury and inflammation. Additionally, it modulates dysphoric states and drug-seeking behaviors in addiction studies, although its effects on mood are dose-dependent, with higher doses potentially inducing aversive responses, which is a characteristic area of study for KOR agonists.
