Description

(D-Arg2)-Kyotorphin Acetate Salt is a synthetic, biologically active peptide derivative of the endogenous neuropeptide kyotorphin. This compound is valued for its enhanced metabolic stability and specific receptor interaction compared to its L-isomer counterpart, making it a critical tool for advanced neuroscience and pharmacological research. It is primarily utilized by researchers and developers in the pharmaceutical, biotechnology, and academic sectors investigating neuropeptide systems, pain modulation, and novel therapeutic agents.

Application

• Neuroscience Research: Used as a stable, potent analog to study the kyotorphinergic system, receptor binding, and signal transduction pathways in the central nervous system.
• Pharmacological Studies: Serves as a key reference standard and active agent in preclinical studies for analgesic mechanisms and drug discovery targeting neuropathic pain.
• Biochemical Assay Development: Employed in the development and validation of high-throughput screening (HTS) assays and ELISA tests for peptide detection.
• Peptide Chemistry & Conjugation: Acts as a building block or target molecule for developing peptide-drug conjugates or fluorescently labeled probes for imaging studies.
• Academic & Institutional Research: Fundamental research tool in university and government laboratories for graduate and postdoctoral studies in neurochemistry and physiology.
