Difelikefalin peptide powder, CAS 1024828-77-0, high-purity CR845, research-grade KOR agonist, difelikefalin for pruritus research, peripheral opioid peptide, lyophilized difelikefalin

Difelikefalin (CAS 1024828-77-0), also known as CR845, FE-202845, and Korsuva™, is a synthetic, peripherally selective κ-opioid receptor (KOR) agonist. It acts by binding to peripheral KORs to modulate pruritus, inflammatory signals, and without significant central nervous system penetration, avoiding central adverse effects like respiratory depression. This tetrapeptide is a key research tool for studying itch mechanisms, neuro-immune interactions, and analgesic development.

Key Features & Advantages

• Peripheral Selectivity: Limited blood-brain barrier penetration minimizes central side effects.
• High Potency & Selectivity: Targets KORs with minimal cross-reactivity to other opioid receptors.
• Rigorous QC: HPLC, LC-MS, and NMR confirmation for batch consistency.
• Low Endotoxin: ≤1000 EU/mg (standard for research-grade peptides).
• Flexible Packaging: Available in mg to g scales with custom vial options.

Research Applications

• Pruritus Research: Investigating uremic pruritus in hemodialysis patients and chronic itch mechanisms.
• & Inflammation: Studying peripheral analgesia and anti-inflammatory pathways in post-op and chronic models.
• Neuro-Immunology: Exploring KOR-mediated immune cell modulation and neuroinflammation.
• Pharmaceutical R&D: Reference standard for formulation, bioactivity, and safety profiling.
• Neuroscience: Analyzing peripheral opioid signaling and sensory neuron function.
