19F containing substrates serve as attractive
reporter molecules for NMR and MRI studies. Applications for in vivo studies are limited by low spin
densities due to restricted concentrations. Using hyperpolarization techniques,
such as Chemically Induced Dynamic nuclear Polarization (CIDNP), this
constrained can be overcome. So far, 19F hyperpolarization generated in D2O, which is a prerequisite for an in vivo application, could only be documented
using laser photo-CIDNP. In this study the successful hyperpolarization of a 19F
nucleus in in 3-fluoro-DL-tyrosine in its free and a complexed form using D2O
as a solvent is presented using a simple LED photo-CIDNP device.
