Description

D-Alanine, D-Arginyl-D-Tyrosyl-D-Threonyl-D-Valyl-D-α-Glutamyl-D-Leucyl- CAS NO 868844-53-5 is a high-purity, synthetic peptide sequence composed entirely of D-amino acids, offering unique stability and resistance to enzymatic degradation. This specialized configuration is critical for applications requiring peptides that are not metabolized by standard biological pathways, providing a distinct advantage in research and development. It is an essential building block for pharmaceutical researchers, peptide chemists, and biotechnology companies focused on novel therapeutic agents, diagnostic tools, and advanced biochemical studies.

Application

• Pharmaceutical Research & Development: As a key intermediate in the synthesis of novel peptide-based drugs, particularly those targeting conditions where metabolic stability is paramount.
• Biochemical Research: Used in studies of enzyme specificity, protein folding, and the structure-activity relationships (SAR) of D-configured peptides.
• Diagnostic Reagent Development: Serves as a component in the creation of specialized assays and probes that utilize D-amino acids for enhanced stability.
• Peptide Library Synthesis: A valuable building block for constructing diverse peptide libraries for high-throughput screening in drug discovery.
• Antimicrobial Peptide (AMP) Studies: Investigated for potential use in designing stable antimicrobial agents resistant to proteolytic breakdown.
• Neuroscience Research: Applied in research exploring the role of D-amino acids in neurological functions and signaling.
