GABA is one of the most important inhibitory neurotransmitter in the central nervous system. Knowledge of changes in the GABA metabolism can help to understand different disease pattern. Therefore, the ParaHydrogen Induced Polarisation can be used to enhance signals for MR studies. In this contribution we described a new method to hydrogenate unsaturated organic amines in aqueous solution and present first spectra of hyperpolarized vigabatrin, allylglycine and GABA. All spectra were detected at 7 T. This new approach opens the way to hyperpolarize further biologically important molecules which were inaccessible to PHIP until now, like amino acids and peptides.
