Description

Dynorphins CAS NO 74913-18-1 refers to a class of endogenous opioid peptides that play a critical role in modulating pain perception, stress responses, and neurological functions. This compound is of significant value for advanced research in neuropharmacology and the development of novel therapeutic agents targeting the central nervous system. It is primarily needed by pharmaceutical R&D laboratories, academic research institutions, and biotechnology companies focused on neuroscience, pain management, and addiction studies.

Application

• Neuroscience Research: Fundamental studies on opioid receptor systems, neuronal signaling, and brain circuitry.
• Pain Mechanism Investigation: Research into endogenous pain modulation pathways and the development of non-addictive analgesics.
• Psychiatric Disorder Studies: Exploration of its role in stress, depression, addiction, and other neuropsychiatric conditions.
• Preclinical Drug Discovery: Serving as a reference standard or active pharmaceutical ingredient (API) in early-stage therapeutic development.
• Academic & Clinical Studies: Utilization in university laboratories and clinical research settings for peer-reviewed experimental work.
