Descrição geral

In contrast to Fmoc-Lys(biotin)-OH, this novel biotin-labeled amino acid has excellent solubility in DMF and other solvents used in Fmoc SPPS [1]. The PEG-spacer restricts hindrance between the peptide and avidin, leading to better biotin binding. Furthermore, the hydrophilic nature of the PEG minimizes non-specific interactions that can arise from the spacer group becoming buried in the hydrophobic pocket of proteins.For recent applications, please see [2,3,4].

Aplicação

  • Unbiased peptoid combinatorial cell screen identifies plectin protein as a potential biomarker for lung cancer stem cells: Utilized Fmoc-Glu(biotinyl-PEG)-OH in the synthesis protocol for peptoid libraries, contributing to biomarker discovery in lung cancer research (AC Raymond et al., 2019).
  • Identification of side arm-modified DOTA scaffolds as multi-site binding ligands for cancer cells over normal cells: Included Fmoc-Glu(biotinyl-PEG)-OH in a synthesis protocol to enhance biotinylated scaffold properties for selective cancer cell targeting (V Rustagi, DG Udugamasooriya, 2019).
  • TANGO-inspired design of anti-amyloid cyclic peptides: Employed Fmoc-Glu(biotinyl-PEG)-OH in the synthesis of cyclic peptides aimed at studying amyloid protein interactions, crucial for Alzheimer′s disease research (X Lu, RM Murphy, 2016).
  • Converting a weaker ATP-binding site inhibitor into a potent hetero-bivalent ligand by tethering to a unique peptide sequence derived from the same kinase: Used Fmoc-Glu(biotinyl-PEG)-OH in developing new kinase inhibitors with improved binding properties (SR Kedika, DG Udugamasooriya, 2018).
