Description

Dynorphin (1-11) CAS NO 79985-34-5 is a bioactive peptide fragment derived from the larger dynorphin A precursor, playing a significant role in opioid receptor signaling and neurological research. This compound is crucial for scientists investigating pain pathways, addiction mechanisms, and neuropsychiatric disorders due to its potent and selective activity. It is primarily needed by research institutions, pharmaceutical R&D departments, and biotechnology companies focused on neuroscience and analgesic drug discovery.

Application

• Neuroscientific Research: Used as a reference standard and tool compound for studying κ-opioid receptor (KOR) activation and signaling pathways.
• Pain Mechanism Studies: Critical for in vitro and in vivo research into endogenous pain modulation and the development of novel analgesic targets.
• Psychopharmacology: Employed in research models for addiction, stress response, depression, and other neuropsychiatric conditions influenced by the dynorphin/KOR system.
• Biochemical Assay Development: Serves as a key ligand in receptor binding assays, functional cell-based assays, and high-throughput screening (HTS) campaigns.
• Pharmaceutical R&D: Utilized in the discovery and preclinical evaluation of new therapeutic agents targeting opioid receptors.
• Academic Research: A fundamental reagent for university laboratories conducting basic research in neurobiology and peptide chemistry.
