A Unimolecular G-Quadruplex that Functions as a Synthetic Transmembrane Na+ Transporter
摘要:
We describe the covalent post-modification of a hydrogen-bonded assembly with the subsequent formation of a potent transmembrane Na+ ion transporter. Olefin metathesis is used to cross-link all 16 guanosine subunits in a lipophilic G-quadruplex. The resulting unimolecular G-quadruplex folds in the environment of a phospholipid membrane and functions as a Na+ ion transporter as judged by fluorescence and 23Na NMR transport assays.
