Uses:
Solid-Phase Peptide Synthesis (SPPS):
Fmoc-Lys-OH is a fundamental building block used in the Fmoc strategy for synthesizing peptides. The Fmoc group temporarily protects the alpha-amino group during the step-by-step assembly of the peptide chain, preventing unwanted side reactions and ensuring precise, selective attachment of amino acids.
Synthesis of Functional Peptides:
Because lysine has a reactive side chain (ε-amino group), this compound is widely used to introduce specific functional tags into peptides. It serves as a versatile precursor for synthesizing:
Fluorescently labeled peptides: By modifying the side chain with dyes like Pacific Blue (PB), Carboxyrhodamine 110 (CR110), Cy5, 5-FAM, or 5-TAMRA, researchers can create peptides for cellular imaging, tracking, and FRET assays.
Biotinylated peptides: Used for affinity capture, immunological assays, and molecular probe construction.
Click chemistry handles: Side chains can be modified with alkynes or azides for highly specific post-synthetic conjugation with drugs, PEG, or other proteins.
Ergogenic Supplements (Historical/In Vitro Context):
Some literature notes that amino acid derivatives like Fmoc-Lys-OH have been explored commercially as ergogenic supplements. They are theorized to influence anabolic hormone secretion, supply fuel during exercise, and prevent exercise-induced muscle damage, though this is primarily an in vitro or historical note rather than a primary current research use.
Orthogonal Protection Strategy:
The Fmoc group can be selectively removed under mild basic conditions (e.g., piperidine) without affecting other acid-labile side-chain protecting groups (like Boc or Trt). This orthogonality allows for precise control during complex multi-step syntheses.
High Chemical Stability & Compatibility:
It is highly compatible with standard Fmoc-SPPS conditions and common coupling reagents. The protecting groups remain stable during synthesis but can be cleanly removed when needed, ensuring high yield and purity of the target peptide.
Versatility for Multi-Functionalization:
The unreacted ε-amino group on the lysine side chain provides an excellent attachment point. Whether introducing fluorescent tags for multi-color imaging, biotin for detection, or PEG linkers to reduce steric hindrance, Fmoc-Lys-OH offers a highly flexible molecular scaffold.
High Purity and Quality:
Commercially available Fmoc-Lys-OH typically boasts high purity (e.g., ≥95% or up to 99.34%), making it highly reliable for sensitive research applications, drug discovery, and proteomics.
