一般描述

与Fmoc-Lys(生物素)-OH相比,这种新型生物素标记氨基酸在DMF和Fmoc SPPS [1]使用的其它溶剂中具有极好的溶解性。PEG间隔基限定了肽和亲和素之间的阻碍,从而使得生物素更好地结合。此外,PEG的亲水性最大程度减少了非特异性相互作用,当间隔基隐藏在蛋白质的疏水口袋(hydrophobic pocket )中时会出现这种相互作用。如需最近的应用,请参阅 [2,3,4]

应用

  • 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).
