Description

Enkephalin, Ala(2)-n-Pentyl-Phenh(4)- is a synthetic, modified peptide analog of the endogenous opioid peptide enkephalin. This compound is significant for research into the structure-activity relationships (SAR) of opioid peptides and their receptor interactions. It is primarily needed by pharmaceutical R&D laboratories, academic research institutions, and biotechnology companies focused on neuroscience, pain management, and novel therapeutic discovery. The product is supplied with a high level of purity suitable for advanced biochemical and pharmacological studies.

Application

• Neuroscience Research: Used as a tool compound to study opioid receptor (e.g., δ, μ) binding affinity, selectivity, and signal transduction pathways.
• Pharmacological Profiling: Essential for in vitro and ex vivo assays to evaluate the analgesic potential and efficacy of modified enkephalin analogs.
• Structure-Activity Relationship (SAR) Studies: Serves as a key intermediate or reference standard for designing and testing new peptide-based therapeutics with improved metabolic stability or receptor specificity.
• Biochemical Assay Development: Employed as a standard or ligand in competitive binding assays, fluorescence polarization assays, and other high-throughput screening (HTS) platforms.
• Reference Standard: Used for analytical method development and validation in quality control laboratories for peptide synthesis.
