Performance of PELDOR, RIDME, SIFTER, and DQC in measuring distances in trityl based bi- and triradicals: exchange coupling, pseudosecular coupling and multi-spin effects

Autor: Andreas Berndhäuser, Olav Schiemann, Jean Jacques Jassoy, Andreas J. Meyer, Sebastian Spicher

Publikováno v: Physical Chemistry Chemical Physics. 20:13858-13869

Electron paramagnetic resonance (EPR) based distance measurements in combination with site directed spin labeling is an important method for determining biomolecular structures and their conformational changes. Commonly used spin labels are nitroxide

Di-copper(ii) DNA G-quadruplexes as EPR distance rulers

Autor: Olav Schiemann, David M. Engelhard, Guido H. Clever, Andreas J. Meyer, Andreas Berndhäuser

Publikováno v: Chemical communications (Cambridge, England). 54(54)

Artificial metal-base tetrads composed of square-planar CuII(pyridine)4 complexes were covalently attached to both the 3' and 5' ends of tetramolecular DNA G-quadruplexes [Ld(G3-5)LdT]4 (L = pyridine ligand) of different lengths. Owing to the planar

Efficient and General Aerobic Oxidative Cross-Coupling of THIQs with Organozinc Reagents Catalyzed by CuCl2: Proof of a Radical Intermediate

Autor: Dirk Menche, Olav Schiemann, Tongtong Wang, Andreas Berndhäuser, Michael Schrempp

Publikováno v: Organic Letters. 17:3982-3985

A general new method for the highly concise synthesis of C-1-alkylated tetrahydroisoquinolines (THIQ) is reported. The CuCl2-catalyzed procedure is based on a coupling of nonfunctionalized THIQs with organozinc reagents under aerobic conditions. It p

Versatile Trityl Spin Labels for Nanometer Distance Measurements on Biomolecules In Vitro and within Cells

Autor: Olav Schiemann, J. Jacques Jassoy, Fraser G. Duthie, Gregor Hagelueken, Sebastian P. Kühn, Andreas Berndhäuser

Publikováno v: Angewandte Chemie (International ed. in English). 56(1)

Structure determination of biomacromolecules under in-cell conditions is a relevant yet challenging task. Electron paramagnetic resonance (EPR) distance measurements in combination with site-directed spin labeling (SDSL) are a valuable tool in this e
