General description

Fmoc-Lys(Boc)-OH is an amino acid derivative used as a reagent in Fmoc solid-phase peptide synthesis.

Application

Fmoc-Lys(Boc)-OH can be used for:
  • The solid-phase synthesis of pentasubstituted dihydroimidazolylbutyl dihydroimidazol-3-ium salts by coupling with p-methylbenzhydrylamine (MBHA) resin.
  • Fmoc-based peptide synthesis of bis-naphthalene diimide, a threading intercalator.
  • Synthesis of ε-Boc-ε-(3,5-bis-trifluoromethyl-benzyl)-α-Fmoc-L-Lysine to be used as 19F NMR based screening tool.

During the treatment of viral or bacterial infections, it is important to evaluate any resistance to the therapeutic agents used. An amino acid substitution arising from a single base mutation in a particular gene often causes drug resistance in pathogens.
