Reduction of transient carnosine radicals depends on β-alanyl amino group charge
Autor: Alexandra Yurkovskaya, Olga Morozova
Publikováno v: Physical Chemistry Chemical Physics. 25:7704-7710
The CIDNP study revealed that the rate constant of reduction of transient carnosine (β-alanyl-histidine) radicals via proton-coupled electron transfer from tryptophan depends on the protonation state of the amino group of the β-alanyl residue.

Photo-SABRE: hyperpolarization of cis-trans photoswitchable molecules by parahydrogen
Autor: Alexey Kiryutin, Vitaly Kozinenko, Alexandra Yurkovskaya
Over the past decade, azobenzene-based molecular photoswitches have emerged as promising control devices in a range of fields, including chemistry, biology, materials science, physics, energy storage and pharmacology. Previous studies revealed that c

Polarizing insensitive nuclei at ultralow magnetic fields using parahydrogen: a facile route to optimize adiabatic magnetic field sweeps
Autor: Alexey Kiryutin, Alexandra Yurkovskaya, Vitaly Kozinenko
Parahydrogen induced polarization (PHIP) provides a powerful tool to enhance inherently weak nuclear magnetic resonance signals, particularly in biologically relevant compounds. The initial source of PHIP is the non-equilibrium spin order of parahydr

Autor: Gerd, Buntkowsky, Franziska, Theiss, Jonas, Lins, Yuliya A, Miloslavina, Laura, Wienands, Alexey, Kiryutin, Alexandra, Yurkovskaya
Publikováno v: RSC advances. 12(20)
Nuclear Magnetic Resonance (NMR) spectroscopy and Magnetic Resonance Imaging (MRI) are analytical and diagnostic tools that are essential for a very broad field of applications, ranging from chemical analytics, to non-destructive testing of materials

Singlet to triplet conversion in molecular hydrogen and its role in parahydrogen induced polarization
Autor: Danil Markelov, Vitaly Kozinenko, Stephan Knecht, Alexey Kiryutin, Alexandra Yurkovskaya, Konstantin Ivanov
An analysis is reported of singlet-triplet conversion in molecular hydrogen dissolved in solution together with organometallic complexes used in experiments with parahydrogen (the H2 molecule in its nuclear singlet spin state). We demonstrate that th
